Mag Blocks is the fun way to learn about the relationships between geometric shapes. First choose one of the challenge cards then try to construct the shape shown on the front. If you get stuck, don't worry. The solution is on the back. As you progress from basic to more complex shapes you'll soon be ready to create your own and that's when the real fun begins! The 48-piece set includes two additional colors, purple and light blue. The additional 24 pyramids and 10 new challenge cards will allow you to create even larger geometric shapes and patterns!
