I'm in fourth. I never seem to have a system that I like. I notice that the students never "go" during recess, they are too busy playing. There are also four or five students who MUST go as we line up for lunch. After lunch, some of the boys want to get out of their seats for water often. It isn't that it is a disruption, but a constant out of their seats activity. How do you manage this in your room?
