1. Chapter 3 Review Mr. Hauser

2. Rules of the Game Working in TEAMS, you will be asked to answer questions from the assigned chapters. You have 30 seconds to write the answer down on the dry erase board. When the teacher says TIME’S UP, a team leader will stand up and show the teacher their answer.

3. Rules (Continued) Each correct answer is worth one point, unless otherwise stated. Teams can lose points for inappropriate conduct, comments, or cheating. The team with the most points at the end of the game wins!
