Trash Ball is a popular game in our middle school. I think most of our departments use it. Divide your class into two groups. Then you start asking your review questions. Within each group the students are numbered so you might have students 1-12 in each group. So your first question goes to student 1 in group A. If the student gets the answer correct, the team gets one point. Then the student gets to throw a huge paper ball (made of paper wadded up into a spherical shape) into a trash can. If the student chooses to throw from across the room and makes it, the team gets 3 points; if the student chooses to throw from 6 feet and makes it the team gets 1 point. So a correct answer has the potential of earning 2-4 points total. Then the next team gets their chance, with student 1B. After that you return to team A, student 2, and so on. Kids love this game because it combines learning academic concepts with athletic prowess!!
