After reading Kate’s Error Finding in Geometry Proofs post which I highly recommend. I had two ideas.
First, that I will be designing some similar activities for my class soon. And, second, that there’s a lot of value in this type of post with the follow up reflections. I’ve recently hit on two activities that I thought were worth sharing so here goes.
Row Games Stolen from Kate at f(t). Basically, pairs of problems with the same answer. Each partner works one of the problems, then they compare answers/results. Lots of self checking, and error analysis, and discussion. Here’s the worksheet I made.
Problem Solving This was supposed to be the warm-up problem for today’s algebra class, but it turned out to be a good problem, and I’m going to use it again tomorrow, with a little more structure to the assignment. Note, I won’t pass out the second page, but I find it helpful to know the correct answer and to have a few different visuals ready before presenting a problem.
