hi i think this means how your setting is layed out. having different areas for different types of play such as a quiet area , a painting area a dressing up area, site these with a table and a few chairs so they can work in small groups. Also having a mat area to bring them all together for story telling.An outside area with climbing frames, footballs etc helps thier physical and social development, all the others help their social, communication, etc developments hope this helps.
