This document discusses approaches to fostering self-expression and creative thinking in children. It advocates for using the emergent approach, where a topic develops as children and teachers investigate it together based on the children's interests. Principles for using this approach include generating children's ideas, keeping the curriculum child-centered, and using questions to provoke thinking. The document also discusses using self-expressive materials and conventional activities to develop thinking skills like matching, grouping, ordering, and conserving.
