This is a great way to review before an exam. This interactive powerpoint Jeopardy game asks questions with varying degrees of difficulty that students can choose. The topics include operations with signed numbers, properties of arithmetic, exponents and roots and order of operations. I usually have my students work in teams and any group that gets the right answer when time is up, gets the points. This encourages students to keep working even if they aren't the fastest in the class. My students really respond to this.
