Sets of educational blocks are described wherein special volumetric relationships are combined with visually distinctive geometric shapes. In one set of blocks a common cube is cut into distinctive segments along a single slice to form particular polygons. In another set of blocks a common cube is cut in a manner to provide polyhedra of distinctive appearance with related outer segments used to fill out the common cube. Particular volumetric relationships between the polyhedra and their related segments are described.
