Function Composition

Function Composition

RULES

1. You must rotate the whiteboard through your group for each question. The same person cannot solve every time.

2. The first minute on the timer is for your solver to work alone (and for you to attempt). The second minute will be for you to help them, but not do it for them. They must keep the marker in their hand at all times. At the end of the two minutes, every group will hold up their board.

3. Every correct answer will earn you one point, you can shoot your trashketball to earn more!
