I know a longer recess is probably not possible, but I love the idea of opening the playground for a half hour before school starts to give students time to play before class. While I was out on maternity leave I didn't want to get out of our normal before school schedule, so my son and I still got to school at the normal time, but I let him play on the playground until it was time to go to school. He loved this change and I saw positive changes in his behavior. I wish I could say that we continued this when I returned to work, but that didn't happen. Maybe I'll make it a goal to do it once a week from now on.
