I started using house points after struggling to gain control of my middle school classes. I decided to let go to my natural instinct of shushing and yelling and decided to initiate both an individual and a full-class reward program. After the first week implementing house points, I had full classes participating in discussions and volunteering to read WITHOUT my begging and prompting! It was amazing!
This free resources comes with instructions, who to win and lose house points, and reward incentives.
