If you use PBIS in your classroom a great positive reward and visual motivation tool is this token system. To keep things exciting you can change it through the seasons. Fill a cup with 10 or more chips, remove a chip for negative behavior, add a chip for positive behavior. Use the incentive chart so that the student knows what they are working for. At the end of the day count the chips. This is great for reinforcing positive behavior, and holding the student accountable for their choices.
