This session will explore ways to incorporate loose parts play, developed by Simon Nicholson and the CLASS tool. The need to create with no formal materials has benefits for children inside and outside the classroom. Adding loose parts play materials enhances Concept Development; by allowing children to solve problems through analysis and reasoning when choosing and using lose parts materials, as well as enhances creativity, while planning what materials to use, producing their vision, making it come to fruition. By encouraging children, asking open ended questions, mapping actions, scaffolding to help children with solving problems and how the materials they use and build with connect to their real lives; the Instructional Support domain of CLASS will expand learning and understanding all while increasing and help children persist in play.
