Yes, it's Math! And it's Fun! Wedgits To Go are rhombus and octahedral shapes – or simply put, wedge-shaped plastic blocks that can be stacked, nested, aligned and arranged. Start with a basic pyramid, move onto a double diamond, and then go beyond standard geometry to structures far more fanciful with the Wedgits To Go! Wedgits To Go includes 35 pieces & sample design cards in a sturdy travel case.Ages 4 and up.by Imagability
