Rules 1.Group #1 picks a question off of the question bench. While they are working on their question, each group should do the problem. 2.If Group #1 gets the problem right, they get the points. If they get it wrong, I will pick a group at random and they get three seconds to answer. If the selected group gets it right they get the points. If they get it wrong, then I will pick another group until someone! gets it right. 3.Winning team is team with most points at then end. Yes, you get bonus points.
