Crumple and Shoot
Unit 2 Equations
Crumple and Shoot (also known as Trashketball) – powerpoint of equations with variables
on both sides of the equals sign. Students work in teams of 4, each studnet has a number
from 1-4. Every student does every problem on white board. I use a random number
generator to call a number from 1-4. That student holds up their board – if the answer is
correct, their team gets one point and they have the opportunity to get extra points by
shooting a piece of scrap paper into our recycle box. I have a “one point line,” “two point
line” and “three point line” from which to shoot to make extra points. Students are
encouraged to work together with their team to complete the problems since they never
know who will be called to show the answer. Great communication encourager.
