Anyone who follows education has probably heard of flipping the classroom, a model that entails having students watch video lectures at home so that they can use classroom time for discussion or group projects. But Canyon View Elementary is taking things a step further and flipping school lunch – joining a small, but growing number of schools across the country that are sending kids off to the playground before inviting them inside to gulp down a carton of milk with their PB&J.

At Canyon View, the practice has cut food waste in half, because kids work up an appetite and no longer feel rushed to get outside and play, said Principal BJ Weller. “We’ve found it very beneficial to our students. We’re seeing fewer health complaints. They have more energy and seem more focused and willing to learn.”

Research also has shown that students attending schools with “reverse lunch” schedules make healthier food choices. One study found a 54 percent increase in the consumption of fruit and vegetables.
