The document discusses the importance of teaching pre-number concepts to young children. It argues that learning pre-number concepts builds the foundation for understanding mathematical skills. The document outlines Piaget and Bruner's cognitive learning theories, which support teaching pre-number concepts. Specifically, it proposes activities to teach determining quantities ("as many as", "more than", "less than") and arranging objects by size using beads, balls and blocks. These activities align with Piaget's view that concrete experiences are important in the preoperational stage of development.
