Teachers will learn how to set up treasure baskets that encourage heuristic play: containers filled with easy-to-find items that support explorations in emergent language, math, and science skills. Encourage children to discover the sounds that a metal cup makes when banged on the floor. Invite them to feel the velvety texture of soft fabric or the bumpiness of a loofah sponge. Let them explore what a wooden ring and a cotton handkerchief can do together.

Through his explorations, the child is answering some fundamental questions: What is this and what can I do with it? Later, he will add to his knowledge: What else can this do and what can this become? This is cognitive development in action!
