What are the school rules/classroom rules and how are they enforced? What are the procedures the teacher uses to make everything run smoothly in the class?

I feel like the two questions posed go hand in hand. The classroom rules are written vary largely on the back wall in the classroom. Each rule was agreed upon by the entire class. I think that is a novel way to create rules for the class. Not only do the kids create and agree on the rules before the school year starts, but they are held accountable by their classmates as well. Its like a contract, the kids all sign the bottom, stating that they will follow the above rules. I can't remember them all right now, but some of them are: Raise your hand when speaking, be respectful of others, stay in seat, etc. 

To make the class run smoothly, the teacher enforces the rules of the classroom. I have also noticed that he is very good at being patient, looking at the ground and waiting for the class to be quiet before he continues teaching. The students know him and his teaching style, so they have caught on pretty fast on the way things are run. They don't fight the system, which is so great. He also chooses different children each day to be the line leader, or the kid to take the library books to the library, etc. That way each kid gets a chance to be the leader for the day. Most of all though, he is a friend to the students and a person they can trust.
