1.Play in groups.
2.Pick a category and a point value.
3.The teacher will click on the chosen box for the question.
4.If a group is correct, they are awarded the point value of the question and have
a chance to continue the game, if not it will be deducted.
5.Other groups have a chance to steal the question and answer it. If the group got
the correct answer they will be awarded the point value, if not it will be deducted
two times the point value.
6.The values disappear after each question.
7.The teacher will Click the “Back to Panel Board” button on the slide to return
to the main board.
8.The game will continue until all questions have been answered.
