Place the Student Selector on the overhead projector and give it a spin. It automatically selects one student from each team even if you have different sized teams working at once! Select one student from each pair, triad, or team of four or five to respond to your question, start the team project, or fill a role such as Materials Monitor. The randomness of the spin ensures that everyone is participating about equally, and it keeps everyone on their toes because students never know who is going to be called on next. This little management tool has been a longtime bestseller!
