Great visual whole-class incentive.you can adjust the size of the brownies to make incentives easier or more challenging to earn. You don't have to reward them with actual brownies--let the class suggest incentives they're motivated to earn!
Potato head as a whole group behavior incentive. When the class is caught being good or behaving appropriately as a whole, we allow a student to add a Potato Head body part. Potato Head is completely together, we have a celebration.
