Yesterday, ds#2 had to "make change" for his MEP lesson. Not wanting to do this on paper, I took out our play plastic coins and a money puzzle in which half the pieces had priced items pictured on them.
I gave ds#2 money and asked him what to buy something and then figure out how much change he should get.
Ds#1 & ds#3 though that was great fun so I let them get out the large money kit and go shopping. I only asked that they make change rather than give exact amounts.
Interestingly, ds#1, who learned addition and subtraction with Math-U-See, wanted a dry erase board to figure out change from $1. Ds#2, learning addition and subtraction with MEP level 2, explained to him how to subtract 2 digit numbers from 100 mentally. Ds#1 picked right up on it, since he has been asked to do that for review at MEP level 3 as well.
