PLAY is children's work. Through play children learn about the world about them. Children need plenty of space - both indoor and outdoor-to work and play. To learn to Ihm satisfactorily with each other they need large blocks of time for outdoor and indoor play. They need much outdoor and indoor equipment and many materials. These are the tools for constructive and creative work and play.
