Turn up the volume on geometry studies with Relational GeoSolids!
The perfect tool for demonstrating the relationships between shape, size, and volume. Fourteen clear-plastic Geometric Solids feature a color-coded footprint to illustrate the connection between two- and three-dimensions. The hollow, size-related spheres, cones, cubes, rectangles, cylinders, pyramids, and polyhedra all have removable stoppers, allowing you to graphically demonstrate volume and size relationships between objects by filling them with sand, rice, or dry filler material below. Includes a Learning About...® Relational GeoSolids Activity Guide.
