The most enchanting schools always have large, open playgrounds with interesting play equipment that leaves many options for creativity.
Student sit at their classroom desk for many hours each day. They are given breaks in between where they go outdoors to the playground. The key to these playgrounds is choice: use the play equipment, run on the field, jump rope, play basketball, or create some new game to challenge friends. A good playground will be large with many different surfaces (blacktop, grass, sand, etc.) to stimulate choice and leave options open.
