Shapes and Symmetry [PDF ebook] 

Symmetry and the mathematical basis of shapes create the 50 engaging and fun puzzles in this book and will help students hone their skills in understanding. All of the puzzles are carefully designed to help young readers increase their speed, confidence, and ability in identifying, analyzing, and constructing various shapes and symmetries/asymmetries, both in the classroom and in real life. Each page of the book features a different puzzle intended to enhance the development of necessary shapes and symmetry skills and an understanding of the mathematical principles that underlie them. The book’s content and methods correlate closely with National Council of Teachers of Mathematics (NCTM) standards and the easy-to-follow language engage even reluctant readers.
