Educational Toy A set of equilateral triangles, squares, and pentagons. Starting with basic shapes, they can be developed into complex and large structures. The set has the same number of pieces as when it was purchased. Box included. This toy has been well-played by the children. I bought it with the hope that they would become good at math. One of them chose a science major, so maybe it was helpful? Pentagons: 12 Squares: 30 Triangles: 20 I checked the BorneLund website, and although the packaging is different, they are still selling it.
