Play, Then Eat: Shift May Bring Gains at School
By TARA PARKER-POPE
Kirsten Luce for The New York Times SWITCHED Children playing before lunch at Sharon Elementary School in Robbinsville, N.J. “Kids are calmer after they’ve had recess first,” the school’s principal said.

Can something as simple as the timing of recess make a difference in a child’s health and behavior?

Some experts think it can, and now some schools are rescheduling recess — sending students out to play before they sit down for lunch. The switch appears to have led to some surprising changes in both cafeteria and classroom.

Schools that have tried it report that when children play before lunch, there is less food waste and higher consumption of milk, fruit and vegetables. And some teachers say there are fewer behavior problems.

“Kids are calmer after they’ve had recess first,” said Janet Sinkewicz, principal of Sharon Elementary School in Robbinsville, N.J., which made the change last fall. “They feel like they have more time to eat and they don’t have to rush.”

One recent weekday at Sharon, I watched as gaggles of second graders chased one another around the playground and climbed on monkey bars. When the whistle blew, the bustling playground emptied almost instantly, and the children lined up to drop off their coats and mittens and file quietly into the cafeteria for lunch.

“All the wiggles are out,” Ms. Sinkewicz said.

“For some reason, kids aren’t losing things outside,” Ms. Sinkewicz said. “The lost-and-found mound has gone down.”
