90 Minute Addtion & Multiplication Engagement

Here is a short screencast covering a lesson with two young students of 7 and 8, we managed to spend the whole time just playing addition and multiplication, everything we did was addition and multiplication...even though we did fractions and division...it was still just addition and multiplication.

We practiced concepts we already knew and practiced writing...this is the only way to attain mastery: practice. So this class was pretty easy for them no stretches nothing new really although each time we do multiplication some of the facts SEEM new event though they've seen them before.

Here they have threes on their fingers, and had to work together to show me eight threes...we get practice with threes AND we get practice with addends because they have to decide who will will show what, three and five or four and four or whatever...

Here we took our threes and laid them out and put them in groups of 9,  talked about 3x + 3 and x being 9 in this case, also talked about  9 times 3 plus 3...and of course 10 threes all being 30.

Writing out what they see in symbol form and beginning to get what equivalent fractions mean, we also talk about common multiples.

Here we build rectangles and count the sides, we count them several ways the sides only for example 4x5 and 5x4 and then what if I have a rectangle where one side is 4 and the whole thing is twenty? What's the other side. What if te whole thing is 35 and one side is 7? What's the other side...? Etc...

This sheet shows the fractions and a pause to write out sixes in a matrix where they CLEARLY see the pattern with the symbols...

Once in a great while I give them a worksheet to take home, I am making webpages at Crewton Ramone's House of Math that have free math worksheets, starting with some first grade math worksheets and fraction worksheets...I also have a kindergarten math worksheet for them to practice writing their numbers and learning their addends, of course it can be used with older students too, it takes lots of practice to write neatly. Right now there's only a few worksheets but I remember when I only had a few videos too, last count I was over 70...

One day there will be that many and more printable math worksheets available there. Not all of them are free but you can get a password for a buck and tat lets you get into a page that has all of them PLUS you can get into the advanced algebra page and my password protected screencast channel that shows how to factor negative expressions...a buck goes a long way.  Here is the open channel, I made this as an alternative to my YouTube channel so teachers and students could watch my vids at school.


Anyhow here is the screencast covering the 90 minute session.
