Here you will see students as young as 4 and 5 years old doing algebra and "advanced" math, without ever knowing it's supposed to be hard.
You are invited to learn how to use this method...

Soh Cah Toa Again.

Here is a fast lesson on the special triangle that is 30, 60, 90 with a hypotenuse of 2. Later, when I talk about the unit circle and dividing all the sides by 2 it will already be somewhat familiar. In the picture above you can see the lesson on Pythagorean Theorem using the blocks to show a 3,4,5 triangle. And bring home the point that we have to take the square root to find the side it's not 25 it's 5 just as it's not 4 on the triangle we are studying it's 2.

During the lesson which I failed to film I used the three period lesson to drive home the names of the sides and we used Pythagoras to help figure out what the hypotenuse HAD to be if the sides were 1 and √3...later I will take an equilateral triangle with sides of 1 cut it in half and talk about the special triangle that is formed. I did this but due to equipment malfunction the little boy accidentally ejected the battery while filming me we lost the lesson. I will record it again another day.

It was good for me as a teacher to spend the time with this student because he asked the exact same questions I get from high school and college students as if he were reading from a script...why does the opposite side change when the hypotenuse stays the same? I usually get them to answer their own questions by asking them questions...

I also think you should approach a lot of this as vocabulary, but not all of it. Many "just memorize it" when in fact you can figure it out if you know the definitions of the words, like hypotenuse: the longest side. We had a discussion about how not all triangles have a hypotenuse, and more.

We already knew x/x = 1 so square root of three over square root of three (√3/√3 =1) being one wasn't a scary concept or hard to understand...he also understand the identity that when you multiply by one you don't really change the thing you multiplied although the symbols may change. Concept based teaching begins to compound.

He also understood that √4 = 2...a common question is where does the 2 come from if the student doesn't fully understand Pythagorean Theorem...I made him do it on the white board (it got erased) at first we had √4 for the hypotenuse but that just a complicated way of saying 2....but the step should not be skipped.

We also applied this same lesson to the 3,4,5 triangle...found Soh Cah Toa for angles and looked at the fractions as RELATIONSHIPS of the sides...for example 3/5 HAD TO BE the Sin 30 on that triangle and he discovered that the opposite side of the small angle was of course shorter than the opposite side of the larger angle (60°) and of course the longest side was opposite the largest angle...the 90. I didn't tell him he figured it out...important concept. You can learn a lot by studying a triangle instead of just memorizing the sides and sin cos or tan for the angles...

Sample Lesson Math Vocab

Here is a sample lesson where we learn a little math vocabulary. It's important to know what the words the mathematics the words sound funny to little kids because they come to us from the Greeks and from Latin...but the concepts are easily understood.

You should also be able to see how the concepts of area and perimeter NATURALLY lead to practice with addends and multiplication and division. This goes well with basic lessons about addition.

I employ the three period lesson and you will note the repetition and lack of the word "no". If they get point to radius when I ask for diameter I tell them that's the radius show me the need for the word NO.

The vid is a little long but it's a useful as a sample lesson and will appear on the Sample Lessons page.

Here is a short vid from a little later in the lesson where we are just playing with blocks and learning and reinforcing addends:

A Glimpse Into Video Tutoring

People always ask, "how do you do it?" or "what goes on in a video lesson?"

See for yourself:

For teachers and parents the other thing I was looking for in the video was the addend you get when you figure out the problem... x + 9 = 15 is the same as 15 - 9 = x AND the same as 1 + 5 = being the addend for the nine.

And here is some Algebra where we learn a lot more than factoring...she gets addends and multiplication and more:

Pretty easy, and fun. The magic (if there is any) is in the blocks and the way they speak to the subconscious mind...also we know there is power in including more senses in the learning process. Getting her hands on the blocks makes a difference...more sensory input = more learning, easier and faster.

If you are interested in video tutoring there's more information here but basically I charge the ridiculously low rate of $ need a set of blocks on your end and google vid chat or skype and off we go.

A little Q&A with Crewton Ramone.

I get a heck of a lot of email. I answer all of it. Eventually. Here are a couple recent ones:

On Wed, Nov 7, 2012 at 11:52 AM,

Dear Crewton,
I have been browsing your website for a while and I love your approach to teaching maths. I have two young children, the youngest is two and a half, and the other one almost five. I found a small set of manipulatives second-hand, and together we've been playing around a bit with them. I have sometimes difficulty finding a good balance between introducing new insights and making sure it all sinks in and they're fluent with it (I am so afraid I will bore them that I tend to charge ahead). So, with the eldest just having started school, I was looking for some tools to bring a bit more structure to our sessions, and to have some materials to make it feel a bit more like 'real' school (he's so keen it's almost funny).

So, I was thinking of ordering a curriculum starter kit, but I had a few more questions. Firstly, have you any idea how long international shipment would take? We're based in Ireland, so virtually the opposite side of the globe. If that boat is taking 6 weeks to reach the west coast, god knows how long before it reaches these shores. We do have friends living in the states (Texas) who are planning to visit us over Thanksgiving. Would priority shipment to their address still be feasible?

Another question I have is what the range of material is that is included in the curriculum starter kit. What kind of ground does it cover compared to school. Is it first grade, or first and second grade? Or does it go further? Mind you, part of the appeal of your approach, I feel, is that it is so different from the way things are being approached in primary school. The more I can keep the disconnect, the better!

Finally, beyond 'straight counting' (addition, subtraction, multiplication, division) where can the visual approach with manipulatives be taken further to? You eloquently demonstrate basic algebra, such as polynomial multiplication and factorization. But what about, say, geometry? To what level has the Mortensen math approach been elaborated? At what point are students meant to join the mainstream approach? With so young children, this is not an immediate concern, obviously! But I'm just curious where this path leads to over the horizon. :)
kind regards,
-D from Ireland

Okay, I think the best way would be to priority mail it to Texas which would take about a week and then they could just bring it with them...however you have to make sure they search it ahead of time and then tape it shut because if they open it TSA is probably not clever enough to close it back up properly...there is no international parcel post anymore, you have your choice between expensive and really expensive. Send me your address and I'll get you a quote...

At that age lots of repetition is required and you play a lot of the same games over and over again...there a host of games and even the pdf of the games and activity them, different activities and building projects keep it fresh and until they know it without symbols then introduce pictures, then symbols the same way they learn to read English...

Here is a link that will answer most of your questions:

And here are some general questions answered:

Very hard to compare the traditional method of grade levels with Mortensen because we teach them math concepts from day one which include algebra and problem solving...once you understand math and can decode the symbols you can see how the basic concepts apply to what they call higher mathematics...I have students bring their text books all the time and then show them with blocks what the symbols mean and WHY they learn the rules and process that they do.

With some creativity and imagination there is very little the blocks can't show...counting through calculus. The Geometry in found in the measurement books. And the books cover many math concepts but certainly not all of them. However it has been my experience that with the firm foundation it gives the math becomes easy and understandable, especially when approached with a "can do" attitude. Students can jump in and out of the mainstream approach with ease...because they can see what they are doing and what the symbols mean.

Take a look around my website and blog and if more questions arise: ask.

Here are some classic algebra problems. Note the use of the blocks or pictures to make some problems easy but by now we are focused on applying the basic concepts...

When you get to the password pages even more will open for you and yours.

Best Regards,


Hi Mr. Ramone,
I am in college algebra at Germanna Community College, recently, I stumbled across your site and was really surprised to see how enjoyable you make learning math. I have struggled with math for so many years, and I have only recently begun to enjoy math and slowly, but surely I am beginning to see how simple even the most complex math problems can be. I believe that having a concrete foundation of mathematical concepts opens up a world of opportunities for an individual, and individuals like you really make a difference in the lives of students.Thank you for sharing your knowledge and gift for teaching, I have told many other students in my class about your website and I know you are making math so much easier for my college algebra class.I would love to utilize your website even more, and If possible, I was hoping I could receive a password for tweets and/or FB postings?
I look forward to hearing from you.


Just don't share it with all your friends:


Do some searches like "Crewton Ramone Kyle" and you will get some precal lessons that way. Also I just uploaded these:

There are lots of vids and blog posts...too.

And please tweet the *explitive deleted* out of this:

~Crewton Ramone

I am tutoring an adult student GED math with strategies and methods from Crewton Ramone’s House of Math. She doesn’t know most of her multiplication tables and has a difficult time retaining information. With help from theh CR website, I am able to teach her area, squares and square roots, percents, ratio and proportion, and solving 2 step algebra equations WHILE she learns her times tables.

Hey Crewton,
Just to clarify, how long does it take to get materials from you?
Thanks! ~CH

to CH
Depends on what you order and how you want it shipped.

If it goes priority mail a week if it goes parcel post for the big items 4 to 6 (6 to 8) weeks...

Also if it's drop shipped by mortensen co it can take a week or two...but often if you order Monday you'll have it by Friday or the following Monday.

Hi again Crewton,
I have two daughters ages 8 and 9 that I homeschool and I am in need of a good math program. Question: Does Mortensen Math work well even if I do not consider myself a math type? I am one of those countless females who were told at a young age that "girls aren't any good at math" and believed it. But I do not want my girls buying into the same lie. And I am really having a difficult time deciding which direction and curriculum to go with this. Last year someone recommended Rod and Staff to me and that was a big mistake. My oldest never did learn how to subtract very well from it.

And my other daughter has only been here with us from China for 10 months now and recovering from orphanage trauma, also having never gone to school before a day in her life until now.

I hope you can help.

Just spend more time on my website and blog.
You and your kids can learn math together and it will be fun for everybody...

More Fun With Addends And Symbols For Little Kids

More from the make math fun file. Two brothers playing and learning together.

Here is a clip from a session with a couple of little boys who are just getting the hang of addends. One is 5 and has had very little exposure to math concepts or numbers and the other is older but has a few 'challenges' but is eager to learn.

The basic concept here is numbers are made out of other numbers and we also get some addends practice by solving for x (which is of course "the trick") where they figure out what's under the cloth...listen to the excitement and the laughter. IT'S FUN.

Math can be fun if you let it.

Also note that like a lot of kids the one child is still not sure of the symbols and what they mean so we do a quick digression into what the symbols mean but then return to the fun part where we are basically playing what's under the cup but have a cloth instead. It's not magic it's math. The younger boy still has to count because he doesn't know his addends. The older boy has more experience and it builds his confidence as he gets answers right.

They both laugh and have fun and although there is always competition and sibling rivalry we use it to best effect as motivation, and we keep it lively, light and fun.

This is a fun way teach addition using addends. As the younger boy gets some practice he won't have to count one by one he'll be able to use the addend to make it faster.

At the end the older boy has made a problem for me...that's fun too. It also tells you if they understand the problems well enough to create one. It helps them attain mastery to make up their own problems and is an extremely effective teaching tool. The children are placed in a math rich environment where they can not fail, and then encouraged to do some self directed learning. Note how we can see the associative property of addition but we never even mention it, but when we do it will be easy to understand because they have SEEN it already.

Obviously I don't have permission to show their faces, you are forewarned, starting Jan 1, 2013 those who don't give permission to use their kids in vids and on the websites are going to get 86'd as 2013 will be all work on the web all the time. My one on one tutoring days are drawing to a close. Will be focusing on groups and if it is solo then the sessions will be used to train others too via youtube vids and web pages and maybe even video products.

Classic Algebra Problems

Here are some videos I've made covering those Perennial Algebra Problems...the ones you'll find in every Algebra Text Book or course.

These "exercises" are supposed to teach you about fog, substitution/evaluation and how to express one thing in terms of another. Instead of f(x) for the function they want f(h) order to do that you have to put x in terms of h.

In this case you have to figure out that x = h/2 and you have to know how to find the area of a triangle...

It helps to understand rectangles and that all it is is A = (1/2)LW but instead of Length and Width we are talking about Base and Height so we get A = (1/2)bh and all we have is a special triangle that is 30-60-90 so the base is h/2 and the (√3)(h/2) or vise versa depending on how you look at your triangle. So then all you do is substitute terms and you're done. Somehow they usually don't make it that easy.

Express The Area Of A 30-60-90 Triangle In terms Of Hypotenuse:

Crewton Ramone Express Hypotenuse In Terms Of Perimeter of a Triangle.

Explaining via Mortensen Math...this is basically the same as this vid except I explain it with the emphasis for teachers and trainers who are using the Mortensen is regular explanation:

In this vid I talk about the concepts of Hero Zero and No Fun Get Back To One as well as the rectangle and SAME.

I left out the concept of the rectangle and squares...and that

(a+b)² = a² + 2ab + b² which should be familiar. (x+1)² = x² + 2x + 1 or x² + 2x + 1²...

Here are little boys playing with the concept of (a+b)² or (x+1)² or (x+y)²:

Important concepts to understand here. They stumble in exactly the same places high school and college kids do...but by the time they are teens these concepts will be second nature.

It got cut off at the end, but basically I was explaining that I give him a hard time because he's my son...but that I was very pleased with his work today. And then they did their usual Crewton Ramone's house of math sign off...but the camera died. Happily the lesson was over so we didn't really lose anything...less than 30 seconds got cut off.

Also we talked about it afterwards and the reason he said 14 when adding 6 + 5 is that he was looking at it upside down and the 6 does indeed look like a 9 when you are looking at it upside down so he automatically decoded the symbols as 9 + 5 and got 14 even though he heard 6 + 5..."I know what 6 + 5 is dad...I've been doing it my whole life!"

A note to those with dyslexic kids...what they "see" and the decoding going on there is usually more "powerful" than what they hear.

More videos and sample lessons you won't find anywhere else with these two are here: There are several hours worth of video there now. You need a password.

Here is some more typical high school algebra:

These are screencasts.

Yet more:

And last but not leaste a problem where we put Pythagoras to the test:

Here a blogpost on using Pythagorean theorem.

All of these problems can be fun if presented properly and if the students have a firm foundation in mathematical concepts. If not they tend to strike fear and cause confusion and delay to quote Thomas and Friends. Just remember rectangles are easy to count and triangles can be a bitch to count so we turn them into rectangles. We also do this with circles and areas under curves.

Be sure to find us on Facebook. And be sure to share this post with kids and teachers you know that are stuck in algebra class.

Pyramid Playing Produces a Preponderance of Productivity.

Playing with blocks makes math easy and fun for little kids...and given the proper tools and games and activities "just playing" with blocks can teach quite a bit of math. In fact this is how the Mortensen Method was born. One of the plethora of fun games and activities in your arsenal should be building pyramids of blocks. Walls and towers are fun too...entire math towns can be built. These towns can teach addends or multiplication or combinations of these topics and MORE.

addends with base ten blocks, addition with base ten blocks, manipulatives,

Playing and having fun with math is foreign to so many parents they are sure it can't be this easy. Actually it is. You have to direct a lot of the learning but over all you will see a lot of it can be self directed.

Here are a few of vids that focus on just this one activity: building pyramids. Starting with this short one where we made nines:

Here is a slightly longer vid where we made 12's:

And here is a longer sample lesson with a child that has a few cognitive challenges, but you can hear him catching on after a very short time. You won't find this vid because it is UNLISTED. You will also find it on the sample lessons page.

In the past I have said I don't want to hit you over the head with it but due to some comments made by well meaning parents and teachers of late I am going to hit you over the head with it:

"Play is our brain's favorite way of learning."~Diane Ackerman
Contemporary American author

"Almost all creativity involves purposeful play."~Abraham Maslow
American psychologist 1908–1970

This is not a new concept:

"Do not…keep children to their studies by compulsion but by play."~Plato
Greek philosopher, 427–347 BC

"Man is most nearly himself when he achieves the seriousness of a child at play." ~Heraclitus, Greek philosopher 535–475 BC

"Whoever wants to understand much must play much." ~Gottfried Benn
German physician 1886–1956

"Play is the only way the highest intelligence of humankind can unfold." ~Joseph Chilton Pearce, Contemporary American scholar

"Play gives children a chance to practice what they are learning." ~Fred Rogers
American television personality, 1928–2003

"Children need the freedom and time to play. Play is not a luxury. Play is a necessity." ~Kay Redfield Jamison, Contemporary American professor of psychiatry

"Deep meaning lies often in childish play." ~Johann Friedrich von Schiller
German poet 1759–1805

"Children learn as they play. Most importantly, in play children learn how to learn."
~O. Fred Donaldson, Contemporary American martial arts master

Now if you so are so foolish as to think that you are wiser and smarter than that partial list of people who understand how important play is, I am sorry for you. Play is not just for recess and math can indeed be taught through play. Further, children who learn this way are not confused when it comes time to take tests, because they actually understand the math the questions on these tests are easy and they usually score not just well but in the top percentile of their peers.

With the manipulatives they can actually SEE what they are doing. It's not like this is another way to do math it is a decoding of the symbols in such fashion that both the conscious and sub-conscious mind can understand and better yet it is presented through play.

Yet More Manipulative Multiplication.

sqaure numbers, base ten blocks, manipulatives,
Make learning multiplication fun and easy playing with base ten blocks.

How to get multiplication mastered. You will have practice. There is no way around it. But you can make this practice fun. And you can make it easier by using some basic memory tools. The concept of a peg. And working in a more natural progression that complements the knowledge as it is acquired instead of just a jumble of facts in ordinal order.

Screencast with boys

Starting with Square Numbers and Pairs a lot of the multiplication can be understood. Then it is easy to add another for three's and of course 10's and 5's are easy so then it's easy to add one more or one less. For example fours can be thought of as one less than what ever number you were counting by of course four so 5 x 6 is thirty and one less six is 30 - 6 = 4 x 6 which is 24. Etc. This needs to be re-cut because the fan messed with the microphone but I STILL haven't had time.


You can use this same thinking with 9's and you can go up AND down with the square numbers...6 x 6 is 36 6 x 5 is 30 one less six and 6 x 7 is 36 + 6 which is 42 and the way you get there easily is with wanna be a ten, six needs 4 to be ten so it takes the 4 out of the six and we get another ten with two left over for 42...4 tens and two. Here is a screencast where I use addends to make multiplication easy for an Autistic student. If it works for her it will probably work for you.  Multiplication by nine is EASY btw. So easy FIRST graders can do it. Click that link and watch the second vid. More explanation:

Using squares as a peg

Multiplication is THE milestone in mathematics and should be taught early and mastered so that all the rest of the math becomes easy...

1st grade multiplication, base ten blocks, manipulative math fun

There are books and worksheets that can help but more than anything you want to PLAY and have fun not beat them to death with math facts that make them hate math and turn them off at an early age. Play with blocks, sing songs do a little each day starting when they are very young and by the time they are 6 or seven most of it will be out of the way. Waiting until 4th grade is INSANITY.

Here is a web page of the books Mortensen uses. The facts mastery books are simply more practice and to be used to reinforce the PLAY you do, which should amount to much more time spent than time you spend on the books.

Also do some web searches for "Crewton Ramone Multiplication"...there are tons of pages and videos on this extremely important concept.  And of course here is the Multiplication page at the House Of Math.

I strongly recommend you follow a lot of the links on this page. I know it's a lot but I can't stress how important multiplication is for making "the rest" of math easy and understandable because it allows you to see patterns and count very quickly. Then search "Crewton Ramone Multiplication" and see the plethora of pages and vids I've made.

Place Value (Numbers Have Names)

My mother was a public school teacher for 30 years. She was certified for K thru 12 but settled into teaching second grade. At the time one of the major hurdles she had was teaching them place value. The curriculum that they had took a few weeks to get the concept across.

I went in there and had in done in two days literally. 100% competency every kid in her class understood the numbers have two parts "the how many part" and "the what kind part" and the numbers tell you how many the places tell you what kind combined with base ten blocks even the SPED kids had NO PROBLEM.

I remember my mother asking wryly, "now what are we going to do for math for the next too weeks?"

So I taught them algebra.

The principal of the school who had a minor in mathematics came to the classroom for something and he stopped at the door as I was casually teaching a group of 2nd graders to factor then they were giving me the factors of problems like x² + 9x + 20...

Anyhow, here are some vids covering a simple and expanded lesson on place value and the names of numbers.

When you start out you can just do the numbers from one to 1 million, three at a time, and then the next day do the numbers smaller than 1. Use a three period lesson. Treat place value like are just learning the names of numbers and the pattern is easy to discover.

I did it all at once for this student because this student was older. He had some questions about the decimal point and where the one-ths place went the way MOST kids do.

Now you can get this handled and understood in a few days...give them a little home work and I would bet on 2 days. [b]THEN YOU CAN DO SOMETHING ELSE.[/b]

I bet if you as an adult were forced to do the same thing over and over again and the subject matter was presented in a way you really didn't understand they be telling to you had ADHD or ADD and would try and pump you full of drugs too.

Place value should be easy. By the time you spend some time on this page you should be quite comfortable presenting these concepts to your students. Remember to break it up and add more meaning as you go. Very little kids only need to learn up to 1,000 to start. Then you can play games and ask questions: what does the 2 in 1,257 mean? Which is more in that number the 2 or the 5? Etc.

There's more place value for little kids on my website, Crewton Ramone's House of Math.

More Manipulative Division.

Manipulatives make division easy and even fun. Here is the page at the House of Math on Division. Here are a couple of videos covering division mostly for parents and teachers. The first is much longer and the second is much shorter.

division with base ten blocks, divison with manipulatives, long division

You don't have to teach division last you can teach it first if you want AND you can use it to teach subtraction and multiplication. Conventional wisdom is you have to know how to multiply and subtract to learn the algorithm for division.

Face it. Kids hate long division. They hate it for a lot of reasons. They haven't mastered multiplication; they don't like subtraction because counting backwards can pose challenges they aren't sure where to start counting. Manipulatives and the concept based base ten block methodology erase all of that. Mortensen Math rocks.

As you can see this is edited a little, the whole thing is available HERE. Only about 5 or 6 minutes is missing, the part covering negative polynomial division.

Here is a follow up video:

Between these to videos, the division page at the hous of math and this blogpost

you should be very comfortable presenting division concepts to your young students.

Practice with easy problems that have no remainders FIRST. Get comfortable. SPEND THE TIME, and do a lot of problems. THEN start doing problems with remainders and bigger problems and problems that are hard to model with manipulatives. All the while DO NOT leave out the part where they draw pictures. When we get to the problems that are hard to use blocks to model we can draw pictures and finally we can move to the the symbols ONLY. And the student knows what they are doing and why and although division may never be their favorite thing, it won't be confusing or hard either.

Now we are serious when we say that you can start with smiley face division books if you like because the baby step approach allows you to teach counting as you go. Here a couple of shots from the beginning of the smiley face series.

Keep in mind these books are made for PRE-SCHOOLERS. It should be obvious that older students can benefit from these books too. I suggest that they start at the beginning  and "breeze through" until it begin to hit their level rather than skip the first books altogether. Here is book one:

modeling division, simple division, division pictures
Here is the end of book one. When you are 4 this is a lot of counting! I have seen people fool around with little 2 and three year olds where the child sits in their lap and just points to the right answer. Also because the price has gone up so far using a sheet protector and wet erase marker to get more milage out them is advised. They are no longer priced as consumables although they were originally intended to be.
division concepts, beginer division, division drawings
He is a scan showing book 5. Expanded notation helps with understanding and is used as an intermediate step. I have a personal problem with the placement of the quotients and this was supposed to get fixed but we never got around to it. When Crewton Ramone comes out with a similar series it will be available in pdf form and some of these oversights and compromises will be fixed. It also had to do with the tech of the day 20 years ago but this is no longer an issue.
long divison, expanded notation division
Remember bigger is funner. Also remember to let them make up a bunch of their own problems that are NOT in the books. As the parent or teacher you should make up some problems too. Practice.
long division, expanded notation, long division with base ten blocks
Each booklet is 20 pages long and designed to be non-threatening. So you can see I am showing you page one and then the end of the books. This is the end of book 10. I have seen 5 years olds complete these books. Kindergarten math at a public school is pretty much a snap after that. Tee hee.  If you can not afford the books just do lots of problems using the blocks and have them keep track of the problems they did in a journal. YOU may have to do a lot of the drawing and symbols for them because the whole point of these books is that they can learn math without the fine motor skills required to work a pencil.

If they have Autism EVEN MORE emphasis on FUN is required.

More on the MAKE IT FUN theme. Here are couple of vids where we play math and the math portion is done many times because it's fun to shoot the walls down. They will do it over and over again because knocking down the walls with a Nerf gun is FUN.

These kids are having fun and the little boy you see there is only 5...note that the NO is removed from the lesson and he is encouraged to try and see if the pieces fit to make ten...ask questions: Is that tall that too short tens and nines and eights.

Out of an hour this was only a small portion of the math we did...this boy Tamu has Autism and is a little shy, but as you can see he is quite able to join in the fun. The idea is to keep the games quick and not to spend too much time on drill. They will get math facts as a matter of course.

Here what you see is us building a house for a lego craft. I also couldn't bring out the camera much because as soon as I did the dynamic changed, and as I have said before the first obligation is to the parents who are paying me money to teach their child. We also had fun building walls and shooting them but I didn't get these guys on camera.

As it turned out this was just the beginning of a large house...which I also didn't get on camera. Tamu got a lot of math facts presented to him and had fun while it happened. Many more exposures will be required before he "knows them" but this is a good start and the repetition is fun not drudgery.

We also did multiplication as well as addends for other numbers but most importantly we kept it fun and engaging. People always ask me how do you make math fun? Just play math.

Seriously. Get out your blocks and fool around, especially when the children are young. You just play and point out math concepts to them as you go. Simple things like a three and a four is the same as a seven...three 3's is square and the square root is 3...that means count one side...etc. Later when they see symbols the explanations make sense...

For more fun and games check Crewton Ramone's House of Math. This page has become popular: Math with Playing Cards. I keep meaning to add more games because there are a lot more games you can play using playing card this pages only gives you a partial list. Use your imagination and MAKE UP some games of your own.

The blocks are only limited by your imagination. Get creative. Have fun. Play math.

Come Play On Facebook Too

For those of you that come to the blog and don't see anything new for awhile go to my facebook page There's always a fun assortment of pics and posts that don't make here to this blog. I try to keep the blog mostly math instruction. Go back and look at the old posts here not just the new ones, use the search engine lately I've been getting email from people asking, "how do I..." Or "where is a post on division...?" or what have you. Search Crewton Ramone division or Crewton Ramone fractions or crewton ramone plus whatever it is. If you don't see what you want and can come up with some specifics I can make a vid for you...just contact me.

Also password is about to change again...if you have paid for a password and don't get an email with the new one let me know...

Them college loans getting to be problematic. Here are several from my main man One Stone:
Make math simple. Make it fun. Make it child's play.

These are just a very few of the things you'll see on the facebook page.  Here is a fun vid using lego to make a model of  The Antikythera Mechanism:

Some fun stuff about global warming:
New study shows half of the global warming in the USA is artificial: "The new rating method employed finds that station siting does indeed have a significant effect on temperature trends."

Then read this:
Bombshell: Koch-Funded Study Finds ‘Global Warming Is Real’, ‘On The High End’ And ‘Essentially All’ Due To Carbon Pollution

Do really think the Koch brothers and a guy who has lied before and been caught red handed lying are doing science or are they doing politics? Anyhow, there are 215 comments as I post this and mnay of them are interesting. My favorite part about those with the strongest "belief in" global warming is they can't do basic math and when I say basic math I mean algebra, calc and statistics and yet they are smug and make comments about deniers and flat earthers when I can assure you most physicists that I know won't even enter into the conversation because "it's like trying to talk about geology with Christians who think the earth was created 6000 years ago. Not worth your time." 

What is the heat index of CO2? What Percent is CO2 in the atmosphere?

Here is another fun article also read the comments:

“It is the greatest scam in history. I am amazed and appalled and highly and offended by it. Global Warming; it is a scam.” -Founder of The Weather Channel John Coleman.

The whole consensus thing is kind of a joke. BTW I worked briefly as a resource tech for the Solar Observatory on Haleakala. There was a time when Al Gore had me fooled too but then some solar physicists sat me down and made me do the math...there are a couple of them who are at the other end of the spectrum and are predicting a Mini Ice "solar physicist predicts mini ice age". I am not allowed to name names or cite them due to a little non disclosure agreement I signed.

Besides global warming there's stuff about education and drugs too: STOP Mandatory Mental Screening and Drugging of our children

Ph.D. in food stamps – the rise of food stamp usage among those with advanced degrees. Record number of households on food stamps.

The point of the endeavor called Crewton Ramone's House Of Math is that the mathematics opens up a whole new world of analysis and critical thinking not available to the innumerate. It makes it easier to spot the BS you get in the news. It allows you to see through some of the lies when you can look at their data and see the flaws. For example with the hockey stick people who can do math pointed out that no matter what data imputs you entered you ALWAYS got a hockey stick...anyway the facebook page get stuff everyday from me and others to. Come join in the fun.

Long Division With Base Ten Blocks

UPDATE: Here is yet another post on division due to the fact I see people showing how to use base ten blocks that are less effective than they could be. This one includes the #1 video hit for division with base ten blocks.

UPDATE: Divinely Dandy non Difficult Division is DONE! (See below.)

There is now an in-depth post at The House Of Math about Long Division With Base Ten Blocks.

Long Division. Not well loved among students. It's EASY if you understand the concepts. And here we will add a little about square roots too....just for fun. Just because we can. Just because you should cross teach whenever you get the chance so your students can see how it all fits together into one language.

Start simple and work your way up. Remember degree of difficulty...and the other 5 basic concepts. We are fooling around with rectangles and counting. Some call this multiplication and subtraction and others call it division. Bottom line: we are counting. And one more time computation is not mathematics. Computation is how we DO mathematics. Today I found myself with an older student and I told him I don't care about the computation at the moment...I want you to understand the concepts...we'll do the computation later...we trying to find the area of a shaded region with a square and a circle inscribed where the only information was the radius of the circle. But step one was knowing I had to do subtraction. But I digress.

Observe. Here is a very simple rectangle:

The question arises why don't you use this pattern (above) instead of this pattern:

Well, because we want to keep track of subtraction. Long Division With Base Ten Blocks allows us to see what we are doing.

long division with base ten blocks, math manipulatives, division

We are counting a rectangle that is 4 across and contains 12.  4 is contained in 12, 3 times. The number inside the rectangle is the dividend the thing being divided, and the number outside (the 4) is the divisor and the 3 is the quotient.  We are humans we name everything. "I think I'll call this place Golgatha and move on."  Kids have a hard time reading division because of this. This is solved quite simply by saying 4 is contained in 12 how many times? We read left to right so saying 12 divided by 4 is confusing. Besides we denote that this way: 12 ÷ 4 = 3.

Dividend. Divisor. Quotient.  Simple no argument.  You be surprised at how many people can't figure out the syntax of Multiplier, Multiplicand, Product or think it doesn't matter. To little kids you are right it doesn't matter and you will note you do not hear these math terms in the video below because at the moment this is extraneous information. Later when they are comfortable with the concepts we can start naming names. Meantime we do Long Division With Base Ten Blocks so that it is readily understandable and visually obvious. Once we start getting it down they will be able to do long division in their heads with no blocks and no paper and pencil either. This is called mastery.

Note the lovely blend of symbol and manipulatives. It completely makes sense to he who is but 5.
Now because this is a demo video more or less and because my students are familiar with the blocks we jumped a bunch of steps to a much bigger problem. YOU would NOT do this with your students unless they were quite familiar with the blocks and even then. Do many smaller ones and have them might also do a few where they have to give you parameter just for fun.  Many. More than three.

Here we are going to count how many times 12 is contained in 132. The obvious answer is 11. These are easy static problems. I used train teachers all the time and the first thing out of their mouths after their initial excitement subsided was how do do a problem like 7 is contained in 132. Pat answer: "you don't." You do lots of easy ones where it works out perfectly and then a few where we have remainders like 4 is contained in 13 how many times and 12 is contained in 133 how many times BEFORE you even think of moving to dynamic problems. By then they have the concept and they realize paper and pencil is MUCH FASTER than playing with blocks. Besides that's all the algorithms do is make counting fast. But long division is a bitch if you don't understand the basic concepts and you can't multiply.  Further let them figure out the algorythim for themselves as you direct their discovery in a math rich environment.

So now lets get even bigger and do one that just happens to be square. AGAIN, YOU would NOT do this until you had done many smaller ones and worked your way up here.

But I am going to illustrate and explain each step.  You could do this with 12 is contained in 132 or 13 is contained in 156 etc.
Because Mrs. Irma Hardbottom would accuse your little genius child of cheating if all he they did was write 19 and be done with it, we have to show our work which is again why we pattern with the blocks this way. Across and down.
And you can see other videos on Long Division With Base Ten Blocks where I talk about Hiram the Ant and use little men or animals or dinosaurs to walk along the edges and count. But you should point out that ten 19's are 190 and that one is one 10. Don't get confused with the edges, we are talking about the distance from one side to the other. 
Once we take 190 from 361 we had to do a little work to figure out what was left on this problem. After some figuring they counted 171 which with the blocks was 90 and 81 which was 19, 9 times. They were counting the blocks NOT doing subtraction, if they did subtraction it might have been even easier because all they would have to do is take 0 from 1 and get 0, add 1 ten to 6 tens to get 7 tens (see vids on subtraction)  leaving us with 2 hundreds because we had to take the 9 tens out of one of the hundreds which is how we end up adding 1 ten to the 6 tens and then taking 1 hundred from 2 hundred is EASY.

It's also easy to see that the square root of 361 is 19 and when it comes to notation this is much easier.
So we did 20 just for fun.
And then we were basically done. Here is all of the above in one fairly concise video:

Anyhow go check out the division page at the House of Math for a little more...long division shouldn't be hard. Look for another post about more advanced problems where the rectangles are more dynamic...these are best drawn or done with symbols AFTER the concepts are mastered.

Here is another GREAT post on long division that even has scans of pages from the smiley face books.

People get excited and ask me what they should get when it comes to blocks and stuff...go here for the simple answer.

Here are some more division worksheets (you need a password) and the video on that page teaches you how to use them. YOU could use that vid as a primer and instead of using pencil and paper use the BLOCKS.

"Great book for teaching how to use the blocks! Colorful, clear pictures and cute rhymes make the book fun to read and play around with. We printed the book out, and my 5yo loves how many of the block pictures are big enough to put his blocks directly on top of the pictures. The text plays fast and loose with niceties like punctuation, but is engaging when read aloud.

Most of the book focuses on playing with addition facts up to 10, which gives a solid foundation. But it also delves briefly into such topics as square roots, place value, addition of multi-digit numbers, and a glimpse at multiplication. And in true Crewton Ramone fashion, problem solving with 'x' (basic algebra) is sprinkled throughout. A great intro to playing with math." ~CS, GA.

Ratios With Sarah

Ratios are easy. All you do is cross multiply. Why? And what if you for get the rules? Here is a series of videos staring Sarah who is studying for her GED. This series gets cut off before we finish but what is on vid is worth sharing. Remember this kid is autistic...but I don't treat her with kid gloves (anymore), and she is doing quite well with math. Look for other blog posts where she is featured and prepare to be amazed. Also look for a future post where the autistic savant rears it's head...she is beginning to recall math facts and remember seemingly random facts that she has seen before.

{I'll put a link in when I make the post. Note to self.}

In these vid we begin to see what do when presented with ratio problems and rather than give rules on when to multiply or divide we think about the relationships. Once we understand that then we can start making up rules to describe what's happening and what to do to get the answer. Note I give her no rules. Later she tells me the rules...unfortunately I did not get it on video. But by the last video you can see she understands it. Then and only then do we move on.

Note I put the P1 in front to make it easy to search and find the next vid...P1 Crewton Ramone and Sarah Playing Ratios and Relationships.

Note when I say tricky I am using her verbage because there's nothing tricky about these it's just math.

As they understand it they do it easier and faster.

And here is the final one where she shows she understands it.

After these we move on to problems where it's not just whole numbers but fractions but we didn't get any of it on can see more with Sarah on Sarah's page.

Playing With Cubes

Getting to know a little about CUBES is important. Children need to have experience with numbers. Square numbers are good to be familiar with too and so are cubes. The problem with a lot of base 10 blocks is they represent cubes as...well, cubes. Which makes sense except that then the manipulatives are limited to the third power then. How do you show powers past 3? Simple you don't.

Here are the first 12 written out. But certainly DON'T just write them out as a drill until AFTER you have built them and talked about them and played with them a bit first. Here is a vid called Crewton Ramone Squares, Cubes and Division because it's about squares cubes and division. I'm creative like that.

Mortensen Math keeps it in two dimensions. Arithmatic not physics. (x)(x²) = x³ or (x²)(x) = x³ instead of (x)(x)(x) = x³ this is a subtle but important distinction which allows me to teach very young students higher powers and so called more advanced mathematics.

Before you get to cubes might be a good idea to play with squares and square numbers. My students will write them out several times during a course of lessons. So they see the numbers and have some experience with them. This will stand them in good stead when they take standardized tests. Many students get through high school without ever knowing their squares and cubes and at Crewton Ramone's house of math we go all the way to 25 with these. (And out to 20x20 on the multiplication tables.) Seriously, your kids know the names of the Pokemons but they don't know the name of 17² or 17³...or maybe it's all the characters in Harry Potter...or they can recite lines from Twilight, but you get the idea.

Squares and cubes should be familiar and easy and part of their instant recall just like 2x2 or 10x10x10...and make sure you eventually go out to 25. You have 12 years to get this accomplished. Here is a short video where Sarah and I are studying for her GED and cubes make their appearance...we only go to 12 here.

Crewton Ramone Takes Two

My favorite part about this vid is the comments: people just don't know what to make of me or it. This is a proof of concept vid...needs more work but I want to make math music vids that are current. Like Weird Al Yankovic except for math...change the lyrics of popular songs to explain math concepts...and then have puppets and good looking kids and base ten blocks dancing around to the beat.

This is just a proto-type if you will. I need a small crew to do camera, song covers and puppets and most of all editing.

Anyhow this one was designed for little kids...three to five. And it was designed to be watched more than once...the concept is multiplication by twos...and getting to know the names of the base 10 blocks.

Unconventional. Odd. Different. People not sure what to think. No pocket protector. No nerd glasses. Multiplication by two's for the little kids.

No. This ain't your grandma's mathematics. It's Crewton Ramone for the wee ones. Just a few math concepts at a time. Math needs to be cool again...currently it is the domain of nerds who do not reproduce...

Base Ten Blocks

Using base ten blocks to teach math is extremely effective.

As with any language: the younger the better. This child is 3.

It allows you to present concepts quickly and easily and because the students can literally grasp the concepts you are teaching because they have their hands on base 10 manipulatives you will find that they achieve greater understanding in less time. This is no longer theory. We've had proven and stunning results for decades now.

base 10 blocks, base ten blocks, base ten manipulatives

I have put up many pages and many videos of actual lessons using base ten blocks to teach algebra, using algebra with base 10 blocks to teach basic operations to even very young children or autistic students. The point is you can teach math this way no matter what you back ground or experience with math is. if you are already a math teacher base 10 blocks will make you a more effective math teacher. If you are just starting out you will find you get better results faster with base ten blocks if you are a seasoned teacher with lots of experience you will find you no longer need to fail half your algebra class because you can make math acseesible to ALL of you students using base ten blocks.

If you can get them to teach one another this is optimal.

If you are a homeschooler you can use base ten blocks and begin teaching math like a pro in no time. You will find that even if your math experience was poor you can teach a lot of things to your own kids and they will actually understand it. Factoring polynomials becomes child's play, solving for x, Pythagorean theorem, square roots and radicals percentages an more are EASY. All you need is a little initiative and and open mind. Take you time and you find lesson after lesson here and I often hear parents who are amazed that for the first time they understand distribution instead of just knowing a formula for what to do like FOIL.

One post couldn't possibly teach you how to best use your base ten blocks. But I can point you in the right direction. There has been some demand for a getting started I will be working on that. Meantime, go to the home page at CRHOM and watch the short video with the little kid on the local news...this will give you an idea where you are going to eventually end up. Then watch the one hour overview. After that you can watch more vids or start reading about addition...which will lead you to multiplication and on the way you may do some subtraction and division.

Look where you can go with little kids. This seven year old is evaluating quadratics and it's child's play. Or you could just use these powerful tools for addition and maybe some place value.

Here we are playing with square numbers...again it shows you where we can go with ease. In between the vid above and the vid below check out this page on square numbers.

As long as you can count to nine and form a rectangle and tell if something is same or different we can pretty much go anywhere. Percentages for example or algebra are no problem. You don't need to know where the staircase leads just take the first step as my buddy Albert would say.
