Here are some wonderful game templates (for PowerPoint) where all you need to do is input your own Q and A. These are templates for Jeopardy, Who Wants to be a Millionaire, Hollywood Squares and more.
Or instead of creating a review game for your students, why not have your students create their own. This would make a great end of the year project – assign pairs of students different units. Try and assign students the units you know they had a little trouble with. That way, they get a little extra review in before those dreaded exams, and on top of that, when the projects are turned in, you should have enough different review games for the rest of the year! And if you’re lucky, you may just get some that are keepers for future years as well!
