I decided that I would be a cool mom this morning and gather every one around for a math game. I recently bought some place value dice at the teacher store, and thought we could make use of those. So we roll dice (10's and 1's for the big kids, only units for the 6 yo) and turn it into either an addition or subtraction problem. Each time someone gets the answer the first time, they get a penny. If they answer for someone else or act like they're going to explode wanting to answer for someone else (a big problem at our house) they have to pay the other kid a penny.
I told them that at the end of the game, they could either keep the pennies or exchange them for an M&M (or other small candy).
Guess what the only thing anybody wants to do today is? Obviously I should have waited until everything else was done.
