I divide my class into teams of 3 or 4. After determining which team will go first, we begin the game. This is editable so you can make different versions of the game with harder or easier questions. In this game you will have to forward each slide manually. Teams are given 4 seconds to read the problem and 15 seconds to answer. I sometimes use buzzers where a representative of each group sits in a special section. They must buzz in for their team to get a chance to answer. There are many ways to use this game…I’m sure you will come up with your own version.
