These are the three simple rules I use in my class. Students and parents love it since we can just refer to the rule # when we discuss any misbehavior in student conferences, parent notes, or with administration. Since rule #1 is broad, I like to do an opening activity on the first day of school about the attributes of a model student. We put our ideas on a poster and hang it on the wall the first couple months of school as a reminder. Enjoy!
