This is a plan for a study group to review their homework and find the one problem for which they have the most questions. There is a space for them to fill in the sections of homework they are reviewing. I used this at the beginning of the semester and, once the students did it a few times, it became a regular way to do homework post-mortem. Each group would wind up with only one question for me, and many times a group would have no questions to ask after discussing it with their peers. This method really helped students learn together and cut down on time spent going over homework.
