內容簡介top Magnetic Tangrams 簡介 Hours of fun are in store for kids who test their shape-recognition, pattern-design, and problem-solving skills with this collection of tangram puzzles. A 48-page color-illustrated book presents approximately 150 tangram puzzles plus a summary of rules for solving them and a brief history of tangrams, starting with their origin in China approximately 200 years ago. Included with the book are five sets of magnetic tangrams of varied sizes, colors, and shapes, plus a board with a metallic interior that kids can use to set up their designs and solve the puzzles. A clear vinyl pocket that's bound into the book contains the magnetic board and the seven classic Chinese tangram tiles. Many additional smaller tiles are contained in a drawer that slides out from the book's sturdy spine.
