I keep a behavior chart behind my classroom door. On the chart there is a pocket for each student, labeled with their name and containing five colored slips. When a rule is not being followed they have to remove a slip.
At the end of the day, I had a hard time remembering which rules my kids didn’t follow. I wanted to keep up with what happened and discuss it with parents. So, I copied each rule on cardstock (small enough to fit in a pocket) and laminated them. Each time a child breaks a rule they put a rule slip in place of the colored slip. At the end of the day I know exactly which rule(s) they broke.
