Book excerpt: "This book is for everyone who believes there must be a better, stronger way to teach mathematics that fosters student joy and curiosity, rather than fear and disconnection; a way that demonstrates to children that mathematics is both a mirror and a lens-it reflects who you are and who you are becoming, and it helps you analyze the world around you. A way to see mathematics as a tool to make positive change in our communities and build foundational knowledge and skills to solve novel and complex problems in our world and its future. This book is organized into two main parts. Part 1 describes the fundamental principles, ideas, and vision (i.e. foundations) of culturally responsive mathematics teaching. It also introduces a multidimensional framework for culturally responsive mathematics teaching. Part 2 features a set of chapters that illustrate culturally responsive mathematics teaching in action"--
