This beautiful tangram kit includes the original fifteen-piece set along with a beautifully illustrated instruction guide. They are different from the regular seven-piece tangram puzzle concerning shapes and number of pieces. The regular seven-piece tangram puzzle is made up of five triangles, one square, and one parallelogram. The fifteen-piece tangram puzzle is also dissected from a square but composed of more shapes: four triangles, two trapezoids, one parallelogram, two L-shapes, two semi-circles, and four arch-shapes. 284 pages
