Chapter 2 Review
Rules
1. Each team is selected randomly. On your team’s turn, you have a specified
amount of time to answer the question.
2. Correct Answer = two X’s you can take away from any group (you can split up
who you take X’s from).
3. A correct answer also earns a shot at the basket (4 X shots vs. 6 X shots).
4. Incorrect answer = other teams can answer for one X.
5. You cannot give X’s to yourself unless you run out. If you have no X’s, your next
turn will be for receiving the specified amount of X’s.
