At the end of a Algebra unit on systems of equations, this is a great PowerPoint to use for a review game. The home screen lists numbers 1-12 and teams can choose what number to start with. Click on the number and a problem shows up. Students work the problem. Click again and the answer appears. In the bottom right corner, click 'Home' and it takes you back to the main screen. I use this in many different ways. You can have students shoot baskets or roll dice when they get a problem correct. Students get points for scoring a basket but they must get the problem correct before shooting. This game includes word problems, substitution method, graphing method, and elimination method.
