Tangrams help students comprehend basic geometric ideas while supporting number sense development in engaging, mathematically rich situations.

This new book focuses on the two major experiences in early mathematics education: number and geometry/measurement.

As students work through the 60 engrossing activities in this book, they describe their physical world using geometric ideas, visualize spatial relationships, and reason with shapes and their attributes. They explain their solutions and justify their conclusions while using manipulatives to support their reasoning. Each lesson includes teacher notes, blackline masters, and links to current mathematical content and practice standards.
