Based on the ancient Chinese tangram puzzle, which has 7 small polygons ( 2 large right triangles, 1 medium right triangle, 2 small right triangles, a square and a parallelogram) that fit into a large square. Beyond the square, many designs can be made with the 7 shapes. Players must then make the picture on the chosen card using all 7 tangram shapes. A new game to us at the time, I took it to the hospital when I went into labor with our third child. He’s turned out to be a math wiz!
