We are working on graph sketching right now in non AP Calc. In some ways, it's not a great topic for mistake game as the problems are quite complex. But in other ways its great because there are a lot of procedural things that are rich in concepts and it gives us a good amount of time to really digest those concepts and talk about the why. This was good overall, except that we had made the boards the previous Thursday, before a weekend, which made it take way longer than expected. Good to know not to do that again.
