Classroom rules must be stated and posted the first day of school. This is true for any grade level. The students must know right away what is acceptable and what is not. The classroom rules must state the clear consequences for breaking each rule. The teacher should also post the rewards for following the rules. If your students know what is expected of them and what consequences they face
. you will have more time for teaching. For sample classroom rules you can visit http://www.suite101.com/reference/classroom_rules.
