Erikson Institute Early Math CollaborativeThe Early Math online environment is full of ideas. At the root of these ideas are the Early Math Collaborative’s Approach to Foundational Math and Approach to Teaching and Learning.
This website is designed with a focus on the Big Ideas. It aligns to the Common Core State Standards so that educators and trainers can find what they are looking for according to learning standards. But it also connects those standards to our own Foundational Math Concepts and Big Ideas, drilling down to the heart of what standards intend to do, which is communicate what central concepts children need to understand.
