Every teacher knows the importance of classroom management and a solid set of rules and procedures you introduce and enforce at the start of the year.
If you have no idea where to start when it comes to rules, here is a great list of "The Essential 10" rules and procedures particularly effective in middle school.
I introduce these 10 rules at the start of the year and explain their logic. The posters are very useful as reminders to students of the rule. More important perhaps, they remind students that they are in the wrong if they receive a consequence.
I hope "The Essential 10" posters help you manage your classroom as much as they helped me!
