We spent a good chunk of time on the first day of school answering these questions and share our opinions. We had great discussion! These charts will hang in our room all year to remind us of the expectations we have set for ourselves and our classroom.
Used these this year. These are the best- most clearly stated class rules I've ever had. We added "Be safe." to the bottom of it. "Let others learn." has solved a lot of other mini issues that always come up.
