M & M Math
Dec. 29th, 2009 04:13 pmErika was not really "getting" the less than or equals sign and the greater than or equals sign, plus she was unenthused about subtraction, so I decided today to make it more fun with some M & M's.
I put M & M's on each side of a symbol, and asked her to take away M & M's (eating the ones that were taken away) in ways that preserved the correctness of th mathematical expression. Well, what I actually said was more like, "Ok, now where can you take away an M & M and still have it be right?"
( Picture of M & M lesson )
By the end of several exercises like this, I think she had a pretty good grasp of the "greater than or equals" and "less than or equals" signs.
We also did a bunch of subtraction problems, which was indeed made considerably more fun by being allowed to eat the M & M's that were subtracted.
After we spent some time on M & M math, we did a bunch of other stuff, including having her complete patterns like "1, 3, 5, ..." and "10, 8, 6, ..." orally, without me telling her what the pattern was. All in all, a very good day of math.
