1. Chapter 4 and 5 Test Review Bounceback Game

2. Rules of Bounceback – Students are in two groups, A and B. – Pick a number starting with 1 until everyone in your group has their own number. – Student 1A will get asked a question, if you don’t want to answer the question you say “BOUNCEBACK,” to pass the question to Student 1B. – If you “bounceback” the points double. So, instead of 2 points, the question is now worth 4 pts. – If Student 1B doesn’t want the question they bounceback to Student 1A. If the question is answered correctly, Student 1A gets the 4 pts.
