Loose parts are natural or synthetic found, bought, or upcycled materials—acorns, hardware, stones, aluminum foil, fabric scraps, for example—that children can move, manipulate, control, and change within their play. Loose parts are alluring and beautiful. They capture children's curiosity, give free reign to their imagination, and encourage creativity. With more than 550 color photographs of many kinds of loose parts in real early childhood settings, classroom stories, and a dynamic overview, Loose Parts provides inspiration and information about the ways everyday materials can support open-ended learning, enhance play, and empower children. With loose parts, the possibilities are endless.
