Precalc class after taking (individually) a practice quiz. The way I set up the SBG system, the first time they see a topic, there is no grade, just feedback. Sometimes that feedback is from me, but mostly they are providing the feedback to themselves with help from their peers. They took the quizzes, and I gave them 3 minutes to talk about the quizzes before I showed the key. Frankly, after these 3 minutes, I doubt I actually needed to show the key. I love this system.
