Attached is a picture of one of my students looking at his behavior contract. It includes the rules of the classroom ( sit, quiet voice, gentle hands, and listen). It acts as a reminder for the student of the classroom rules. During a lesson or activity, the student earns a check if he follows the classroom rules and earns a reinforcer or a reward of his choice for a limited time of 5 minutes.
It is successful because it is used consistently and it gives structure to his school day.
