The only time someone should be in "time out" from recess is if ON the playground there is a behavioral situation and the monitors need to separate, calm down, discuss choices/options available and make a plan with a specific child and then send them right back out to try the plan out.

I don't think that needs to be punitive either...more like a regrouping. Recess "pause in playing" for a child should be related to recess problem. Not a homework problem.
