Transform how your students understand mathematics with this resource based on research by Piaget, Kamii, Devlin, DeClark, and Bruner. This lesson explains 10 key principles of how children truly learn math—not through symbols, worksheets, or memorization, but by constructing mental relationships through hands-on experiences. Students explore concepts such as ordering, hierarchical relationships, number sense, mathematical language, and the difference between doing math and merely representing it. Includes discussion questions, reflection prompts, and activity ideas to support conceptual understanding. Perfect for teachers seeking a deeper, research-based approach to math instruction.
