For many elementary school principals, recess is the toughest part of the day. That's when all the trouble starts — the teasing, fighting, bullying, injuries, referrals and suspensions. This video demonstrates the "before and after" effect when safe, fun playtime is introduced in the schoolyard. A trained Playworks coach teaches and runs games designed to build leadership and foster teamwork. As a result, kids are more physically active, and principals and teachers consistently credit Playworks for transforming not just the playground and but the entire school learning environment.
