1. Unit 4B Review
Grudgeball

2. Rules
Once you are in your teams, assign one person to each role: whiteboard recorder, calculator person, facilitator, and extra point shooter.
Each team member will receive a worksheet of all the review problems that will be shown for the rounds. You must show all your work for full credit! This worksheet will be collected for a grade.
The answer that the whiteboard recorder writes must be a team decision!
If your team answers the question correctly, your team may take away 2 pts from the team(s) of your choice. You may shoot for an extra 2 or 3 pts. If the extra point shot is missed, your team still takes away 2 points.
If a team has all their pts taken away, they may “steal” 2 points from another team(s). They may also take part in the extra shot points.
The team with the most points left at the end of the game will receive 5 bonus points on their Unit 4B test.
