This timely book builds on our current understanding of how to effectively teach mathematics, and borrows from the successful frameworks used to teach literacy. It introduces a numeracy framework— sense maker, skill user, thought communicator, and critical interpreter—that supports an integrated approach to math instruction. It considers the mathematical practices students need to learn to construct number knowledge, become mathematicians, and simply “do math”. The goal is to provide multiple entry points into the world of math instruction—a new way of thinking and learning where learners engage in critical thinking about numeracy and act on their knowledge.
