Description
Caleb Gattegno’s approach to math focuses on the process for generating mathematics in the mind. While many believe that math is the skill of a few gifted people, he believed that every student is capable of functioning like a mathematician. By taking abstract concepts and representing them in visible and tangible ways, he found that students can gain mathematical competence well beyond their designated grade levels.
