How to play

• Each team needs 5 large (8.5 x 11) sheets to indicate their choice:– One each marked A, B, C, D, and E

• For each question, raise the sheet corresponding to the choice you believe is correct

• You may change you answer at any time• The point value decreases with time• The teacher will award points to each group

based on when the correct answer was raised
