Gotta thank Kate for introducing me to the Row Game. I also like the idea of using box.net as a way for teachers to upload and share them. But, me being me, I couldn't leave well enough alone. I like the fact that these activities are self checking and that if students find that they have different answers, then there is a mistake. The problem with that is if I create two sets of 10 problems, I would like my students to work as many of them as possible.
So I introduced the "Easter Egg." I have used this concept in the past when doing test review. Basically, I hide wrong answers so students need are a little more alert when looking at the solution to a problem.
How does this work for row games? Well, in the row game, if the partners have different answers, then someone messed up. This opens the door for discussion. But what if they never disagree? Then there was no real need to discuss anything. With the Easter Egg, I will make a couple of the problems diverge, that way agreement doesn't necessarily equal correctness. Now they have to talk even if they get the same answer.
Today I rolled out this row game on slope with my 7th graders. Once they got used to the concept, the did pretty well. I look forward to doing more of these.
I don't know, maybe this defeats the purpose of the row game. Maybe not. What say you?
