Progress with My Behavior Plan

My behavior plan with my student is going very well so far. Last Tuesday I sat down with this student and asked him to collaborate with me to complete this behavior plan. We have decided that some of the behaviors we are going to target with this plan are tapping pencils, working on other assignments during inappropriate times, drawing in class, and talking out of turn. The student identified these behaviors himself, though I guided him by asking questions such as "What behaviors typically cause you to receive minuses (our school's disciplinary program)?" and "What do you think you do during class that keeps you from being the best student you can be?" I also guided him through what he could do to change these behaviors; he will only work on other assignments during free time, and he will raise his hand to speak in class or ask questions.
I also felt it was important that we have my student be completely responsible for his rewards for good behavior. His rewards will be responsibilities such as passing out and collecting papers in class, getting the opportunity to draw during free time, and working on personal assignments during free time. We also set up a scale of consequences for poor behavior: 1st Offense = Warning, 2nd Offense = Minus, 3rd Offense = Referral to office

On my last week in the school, I plan to review our plan with my student and give feedback to his performance so far.
