2. Be seated in groups of four. Turn your HW in on my desk – you will get it back tomorrow. Every group member needs paper and something to write with. Come up with a team name and be prepared to share it with me for scoring purposes.

3. Rules of the game: Assign a number to each team member (#1-4) Each member solves their own equation. One member will add all four solutions together to get the OFFICIAL ANSWER. The official answer should be written on the mini white board and shown to the teacher. The first team to get the correct official answer will be able to give our three strikes to the other teams. When a team receives 5 strikes they are Knocked Out. Knocked out teams can still win individual rounds to strike other teams. Any team the quits, doesn’t work, is disruptive, or cheats will be disqualified and receive NO CREDIT for this activity. Any person talking to another team at any point will be considered cheating and be disqualified. The last team standing will receive 3 bonus points on their test Friday. If all teams get knocked out then all teams that have not been DQed will participate in a sudden death round. Winner takes all!
