Shapes for Exploration

I am designing this tool because my four-year-old student loves shapes, and shapes and patterns are both important and appropriate topics for preschoolers. My manipulatives consist of three large, three-dimensional shapes (triangle, square, and hexagon) each with a “hole” placed throughout the middle of the entire manipulative. In addition, I have 6 thinner manipulatives (3 triangles, 3 squares, and 3 hexagons) each of a different size, yet only one of each shape will fit perfectly through the middle of the larger manipulative of the same shape. I want my student to explore the polyhedra and see the patterns he comes up with.
