Let kids enhance activities incorporating found loose parts with this set of 4 clear Loose Parts Sorting Trays. Made from easy-to-clean plastic, these trays are the perfect addition to nature-based activities in the classroom and outside. Each tray is divided into 6 compartments, encouraging simple classification and seriation while children develop spatial relationships and strengthen their fine motor skills. Introduce an additional layer of sensory exploration using a light source through the clear plastic.
