Many students will soon have more time to play. A new law in California says public schools must give kids at least 30 minutes of recess each day. Other states, like Illinois and Washington, have similar laws.
Some health experts say recess helps kids reach an important goal of getting an hour of physical activity each day. They also point out that playing during recess can help kids make new friends.
But others argue that too much recess eats into learning time. Some schools have cut down on recess. They use the extra time to teach subjects like math and reading.
