RULES• Listen for your number and join your team

members (6 Teams in all)• I will think of a number between 1 and 10…

the first group to guess the number correctly will have the first turn

• Each group will answer one question at a time. After an incorrect answer is given, other teams can steal their turn. No team loses points (only gains)
