In this book, Cathy L. Seeley, former president of the National Council of Teachers of Mathematics, shares her insight into how to turn your students into flexible mathematical thinkers and problem solvers. This practical volume concentrates on the following areas: Making sense of math by fostering habits of mind that help students analyze, understand, and adapt to problems when they encounter them; addressing the mathematical building blocks necessary to include in effective math instruction; turning teaching "upside down" by shifting how we teach, focusing on discussion and analysis as much as we focus on correct answers; and garnering support for the changes you want to make from colleagues and administrators.
