All children attending public schools, or any other schools managed or controlled by the state, that have elementary grades kindergarten through six (6) shall receive in those schools at least twenty (20) consecutive minutes of supervised, safe, and unstructured free-play recess each day. Free-play recess may be considered instructional time for those schools that would be required to extend the current school day in order to meet this requirement. Teachers shall make a good-faith effort to not withhold recess for punitive reasons. Free-play recess is in addition to the requirements set forth in § 16-22-4. As used herein, the term “free play” means an unstructured environment, but which is supervised by appropriate school personnel or staff.
