As exam review each semester (and this year, each trimester), I gave students a group project worth 100 points to come up with review games for each chapter that will be on the exam.
Here is a link to my description. Over the years, I decided to have due dates along the way for things such as writing the review questions. That way, I could grade them ahead of time and have students correct their mistakes before presenting the game to the rest of the class. Before I did that, the games turned into finding the REAL correct answers instead of playing the games.
Here is a link to my rubric. I gave each group a copy of the rubric so they knew in advance how I would be grading them. Then, I filled out a rubric for each group along the way as each due date came.
Here is a link to my reflection piece. The students would each fill this out. After they turned them in, I would give them a chance to discuss what they liked and what they wanted to do differently as a class. Then, I encouraged them because most of the projects turned out really well.
Here are a few pictures of review games:
