Basically what you see here is a math rich environment in action.
Playin is learning. Play with the stuff they like to play with... In this case playdoh and manipulatives, or base 10 bucks.
This screen cast got over 150 hits in a day, I'm pretty sure people were amazed by their ability to multiply more than by the playdoh but you never know with the Internet.
If you like it, share it.
Basically we played and had fun first and learned math concepts second. this play session lasted about two hours you'll the complete lack of symbols interplay we just talked about the concepts, the symbols will come later.
Here you see us playing with addends and subtraction. A lot is going on here... You see Hero Zero wearing his five disguise at the top, first it was a 10 and we made addends for 10 below it and the four-year-old showed me ten take away one in no uncertain terms.
And here we are getting ready for addends bigger than 10.
Talk about making impressions, here we see 6+4 really is the same as 7+3, and they're both the same as 10.
Cutouts for the one I don't talk about talk much about the video. And you don't see it much here either but we did all kinds of map of the cutouts, mostly adding and subtracting and smooshing together.
Looks like an American cheese single. And right there I got about 100 ideas for lessons with a pack of cheese singles... Eat your math lessons, that will get them subtracting--assuming you like eating processed American mucus forming, chemically enhanced for optimum flavored cheese-like substances. I wonder if I could get Kraft as a sponsor. Anyway I can see lots of lessons that could be done with cheese singles.
Here we talked about one whole, then because it was yellow we cut it into a 4 x 4 square using the four block as a guide. First would cut it in half then we cut each half into it quarters and the make up the other way and we talked about equivalent fractions 1/4 equals 2/8, and they could see it. And then we got those in the house and you get what we see here:
This gives a good chance to practice coming by fours and to see 4/16 is the same as one quarter. You can also see a relationship of 1 to 3, 1:3, but we did not talk about it at all I mention it here because it's so blatantly obvious we could show it equivalent fractions the other way keep it simple and fun and don't try to stuff too much in there at a time. Older kids and adults might be ready to make the switches between the two but with the toddlers I made sure it was a coherent lesson with no jumps and perception. It's one square with a strip colored in as opposed into rectangles, one over the other to show ratio and equivalent fractions of one third that way. This one square teaches a lot of math to toddlers as it is. his could just as easily been a lesson about right angles and squares and square root.
"I dunno." I said, "let's just play and see what happens."
Here is a video for the boys help me tell the story. Caution: they may blow your mind with their ability to count.
At the time I made this post using YouTube and Screencast-o-Matic had outages that were commonplace. I put screencasts here for all my teacher friends who have YouTube blocked at skool but then the screencasts stopped working so now I'm going back and finding screen casts that don't work and am replacing them with YouTube vids or links.
This screen cast is titled "Crewton Ramone play W/Clay Learn Math" on both YouTube and Screencast-o-Matic. People ask me if they can use my material on blogs and web posts, lancer is by all means just a link back to wherever you got it.
Here are couple of old posts where they play and learn math:
More fun math activities.
Math rich environment.
Four-year-old math enrichment.
Find us on Facebook... and at the house of math.
I am going to use this playdough idea in my math camp next summer. It is genius.ReplyDelete
Used multi-tens to teach equivalent fractions yesterday.
Using rectangles to convert fractions/teach multiplication/teach ratios simultaneously was more than my client's mother could take. It was so easy, she was crying and laughing at the same time.
