Speed dating in the math classroom.

I’m always looking for ways to let kids practice in class without necessarily even realize that is what they are doing because they are having a little fun doing it. We are working on solving systems of equations and started out by solving via graphing. This way they truly understand what they are finding when solving a system.

Next day I wanted them to do the “set equal to method” (aka substitution when both equations are solved for the same variable.). Not necessarily a hard task but it is something they need practice on solving. So I pulled out Kate Nowak’s (one of my math teacher idols) math speed dating activity. Basically the desks were lined up with two desks per pod. I had 12 groups.

Look at them working so hard! Love them all!

I made 12 sets of different equations and numbered each set. I then handed out a set to each group being mindful of the level of difficulty when I initially handed them out. I told the students they needed to solve their problem in their group and become “experts” at their problem. When they were done I checked their answers and helped clear up any mistakes.

After students had become experts at their problem, I had the student sitting In the middle isle change desks behind them so they were sitting with a new person that had a different problem. (After thinking about this I didn’t necessarily have to do this but it worked.). They students then exchanged note cards and solved the new problem. Here is the great part – if they were confused, they had an “expert” sitting across from them to help! Also I knew the correct answer was their as well. After each group was done I made sure the kids had their original problem in hand and had them “speed date” – one person stayed in their spot and the other person switched to the next table and the whole process started over.

Fun things I saw – it was fun seeing students who sometimes struggle helping other students who were stuck on their expert problem. It was fun seeing the confidence level increase in solving these problems after a few dating rotations. It was also fun when I then had the whole class solve the “special” cases of no solution and infinite solutions when they were done and discuss as a class what was happening in those cases.

Will definitely be using this one again.
