The Robert Wood Johnson Foundation released new findings that demonstrate the benefits of recess for children and their schools:

“When elementary schools create a safe and healthy recess for students, there can be a major impact on individual kids and school climate overall. In schools with safe and healthy recess students are more active, more cooperative, and more likely to use strong conflict resolution tools. Schools also see more drops in bullying and disciplinary referrals, and reductions in the number of conflicts that start in recess, spill back into class, and take up valuable class time to resolve.”
