Class Expectations: All students are expected to treat others with respect. Good behavior is acknowledged and praised. Students are given reminders what what the expectations are. We often have a "Character Counts" lesson or talk sometime during the day.
I have the student's do their own behavior chart:
Green happy face: a good day
Yellow face: self-control issue, usually after reminders, warnings. The student writes what the issue was (usually, talking, not listening, unkind to others) on the behavior chart.
Red face: Second big issue of the day. Improvement is needed. Parent is contacted. The student writes the issue on the behavior chart.
