What is your behavior plan, and what are your consequences? I think the red/yellow/green system is too young for them, but I loved reading about another system yesterday where they can move up or down on a scale- they all start out at good, then they go up to two higher ones than good, or go down to specific consequences (I would never use words like poor because that would probably provoke some "smart-alecky" kid.). I've also used a system where I wrote their names on the board with the number of the rule they didn't follow- and if they got to three, they lost recess for the week/perhaps had a discipline warning notice. Sometimes they could immediately get to three, depending on the severity of their actions. The thing that I need to look at are my consequences- it's like warning, call the parent, then the recess/warning notice. So I'd like to know your plan and consequences- and if they work really well. One thing, too- We only have recess once a week- on Fridays.
