Classroom rules & how are they enforced?

Mrs. Ray's biggest classroom rule that I heard her tell the students' was they needed to ask 3 before me. If she gave directions the students were expected to listen and if they didn't they needed to ask 3 other students before they came to ask the teacher, then she knew they didn't understand not just coming to ask. She had a big stop sign on the wall with this statement in it to help remind the kids.
Some of the procedures she used to make things run smoothly were she was always prepared for the day with each lesson she was teaching as well. Sometimes things would get a little off and she would have to change it up a bit, but I never saw her get frustrated. Mrs. Ray always reminded the students the next step or activity that would be coming up in the day. She had a couple of kids with anxiety in her class so this helped them know what was coming. At the beginning of the day she went through that days schedule as well.
If students started misbehaving she had a Ray buck system in place and they would get a verbal warning and then if she had to talk to them again they would owe her a Ray buck. This helped keep kids on task because they did not want to owe her their Ray bucks. They also got rewarded with Ray bucks for turning in homework on time.
