Take the tangram challenge! Based on the best-selling Book-in-a-Box kits, the Tangram Teasers Book will challenge you to first solve the puzzle by creating the shape shown, and then change it into a new shape with only the number of moves indicated. Just when you thought tangrams were easy, they got harder. But there are three levels of difficulty and so you can start off gently, and then get more and more teased! Try the tangram challenge. But watch out—tangrams are addictive!
