This PowerPoint is to be used to review matrices, Gaussian elimination, etc.
The format is so fun! To play the game, I use a SmartBoard and a couple soft balls like Nerf. The students are divided into 2 teams. They toss a ball gently at the board which pulls up a question. Each team works out the question, and the answer is discussed. Then, the teacher will click the "Go Back" button to return to the home screen where that circle has disappeared so no questions are repeated. Ideally, a SmartBoard would be used but any sort of projector display can show the presentation while the game should be adapted.
You can simply change the questions on the slides to match their purpose for any topic or any classroom lesson. Enjoy!
