I wrote a facebook post about this last year that I think is relevant here.
"It occurs to me that one of my core beliefs as a teacher is in the value of games and game like activities for learning.
Some recent insights: I watched a student struggle with exchanging different values of money and after asking him a few questions found out that board games were not big at home. I might be about to give him my spare monopoly board if his mom is okay with it, and ask if she'll play with him as his homework: games build numeracy.
Today I had to cover for someone and we played Swap! which is like uno but with some twists. It was a social skills class, so this was a pretty appropriate activity. Not only did were the kids good sports about it, the game requires everyone to pay attention to everyone else's moves in order to succeed, and it was fun to watch them really try to do that.
The Payday game has helped kids understand additive inverses and adding positive and negative integers. We're still figuring out how to expand the metaphor to subtraction but we can add a die or a coin and do that too.
We swapped out the traditional dice in shut the box for a d4 and a d12 and changed the rules so that you can do any operation you want with the two numbers you roll. Kids are excited to play.
Kids who refuse other class activities will come up and play a math game, and will even try to learn the concept built into the game if it helps them win the game.
(Additionally) When my class at BAMS invented the game we called Duels, we made the rules work so that everybody had to have the right answer because you never knew who was being called on. This led to kids explaining things to each other and working together. (Ask me about the rules of Duels sometime. It's an ideal game if you are popsicle stick user)."
