Educational building blocks are described which comprise a right prism member and two flat rectangular plates having widths equal to the altitude of the prism and lengths greater than the greatest altitude of the prism bases. One of the plates is attached to each base of the prism so that the flat surface of the plates coincide with the prism bases. The flat plates are so oriented that they are in mirror image relationship to each other. Blocks of this kind may be fitted together to create a great variety of structures and forms.
