Educators create environments that serve children’s growth by providing fluid and flexible spaces, ‘structures for openness,’ which allow for big movement and big play. Smaller spaces may contain or hinder the potential of full-bodied, expansive play. Children need to move their bodies, and are more focused and calm when they do. Physical movement every day, and lots of it, supports healthy brain development. Educators can provide for children’s movement needs, in both indoor and outdoor environments, throughout each day. Open environments and materials allow teachers to step back and watch the play unfold. Calming, de-cluttered environments allow children to see, notice, and choose what to do.
