Rules 1.Divide students into groups of 2 or 3. 2.Pick an order for the groups. 3.Group #1 picks a question off of the “question bench.” While they are working on their question, each group should do the problem. 4.If Group #1 gets the problem right, they get the points. If they get it wrong, pick a card at random (cut out #’s from the last slide) and they get three seconds to answer (this is why each group should work on the question Group #1 selects). If the selected group gets it right they get the points. If they get it wrong, then pick another group until a group gets it right. 5.Repeat step 3 with Group #2 selecting a question off of the “question bench.” 6.Games ends when questions are gone or teacher decides to stop. Note: Pressing the green arrows on each slide takes the user back to the “question bench.”
