Most kids in Chicago's public schools spend just five hours and 45 minutes in school a day. It's one of the shortest school days in the country.
That's why more than half of the city's public elementary schools have no recess. At those that do, it's shockingly short.
"We have a 10-minute recess and a 10-minute lunch at our school," says Wendy Katten, mother of a third-grader at Burley Elementary School in Chicago. "It's not sufficient."
