GRUDGE BALL:
CHAPTER 3 REVIEW
Tuesday November 18 and Wednesday November 19
Grudge Ball: Instructions
1. One question will be up on the board. You will have 3 minutes to complete the problem with
your group.
2. We will start with Group 1. Group 1 gets to answer the question. If they are correct, they may…
• Take one point away from any team –OR• Take a two-point shot to be able to take two points away from a team –OR• Take a three-point shot to be able to take three points away from a team
You are allowed to split points among teams if you are taking multiple points away.
3. If Group 1 gets the answer incorrect, we will move to Group 2 to answer.
4. Once a group answers correctly, we will move to the next question. This time we will start with
Group 2.
5. We will review your questions at the end of the game, so make sure you write them down as
you go!
