1. Go To The Head of the Class-- Review Game

2. Rules: A question starts with a player. If that player answers correctly he/she keeps his/her seat.

3. If the player misses, then the question goes to the next player. If missed, it goes to the next player...

4. …and continues until someone gets it correct. That student moves to the seat where the question started...

5. …and everyone who missed the question moves back one seat.

6. The object of the game is to occupy and keep the #1 seat.

7. Questions with a limited number of possible responses will not be offered indefinitely. A substitute question will be posed.

8. It is important to listen to previous responses. They will not be repeated for you.

9. The first person to receive a question will have a maximum of 30 seconds to answer.

10. Every person after that has only 10 seconds to reply. Be ready when called upon.

11. If the question is on a yellow screen, expect to solve a problem. Have calculator, paper & pencil ready.

12. If the background is orange, name the definition, property, theorem, etc, that supports the given conclusion.

13. If the question is on a green screen, it requires just a short answer.

14. Time to Play:
