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.
These problems include using the distance formula, slope formula, and both the distance and slope formulas. Each slide lists four ordered pairs- there are no diagrams or graphs. The answers are just yes or no, they don't show any work.
