Onion Ball is an activity which teaches students how to generate arguments quickly. Using slips of paper, teachers will make a ball of paper. Each slip will contain a complete argument. After arranging the students in a circle, begin the game by handing the ball to the first student. Students will choose a slip of paper from the outer layer and respond to the argument written on the slip with a complete counter-argument. When they finish, they will throw the ball to another person in the circle. The game will continue until all pieces of paper are taken from the onion.
