I stole the game from one of my colleagues Ted. Students work in pairs to solve a problem on the mini white-boards. For the first problem, Partner A is the only one who can write on the board; Partner B can help and offer advice, but cannot touch the marker. The roles switch for each problem. When they are done, they hold up their board. The first team to hold up the correct answer gets to throw a hacky sack at a target I've drawn on the board, and depending on where the sack lands they either get 1, 2, or 3 points. The throwing of the hacky sack clearly has no purpose other than getting the students up and excited, which kind of reminds me of Solve Crumple Toss, except that they don't have to throw away their work when they finish a problem.

I'm not sure what it was -- maybe I made the problems too hard, maybe I should have given them time in between rounds to finish up their solution even if they weren't the winning team, or maybe I should've figured out a way to get rid of the time pressure. In any case, a couple of teams wound up dominating the game and many students expressed frustration after class that they weren't able to get any of the problems right and they didn't like the time pressure. I tend to agree about the time pressure - after all, it's not about how

*fast*you can do a problem, but how

*well -*but if there's one calculus skill that lends itself to this kind of a game, it has to be taking derivatives using the power rule. It's like the multiplication tables, but for calculus.

I'm really curious if anyone out there has developed the perfect math review game -- one that is fun and competitive, but encourages (or better yet, forces) everyone to participate and doesn't automatically favor the quickest kids in the in the class.
