Abstract: This invention comprises an instructional and game device wherein two elements of the device may be fitted together to form a non-continuous ball which may be bounced, rolled, spun or thrown. The elements comprise, for example, the letters of the alphabet wherein a large "A" and a small "a" may be fitted together to form a discontinuous spherical ball. The letters are formed in a particular rounded format around the exterior edge and include a centrally located notched internal member where the elements are locked together. The individual elements are generally flat and may be readily stacked for packaging. Various constructions or combinations may be built with the letters. Also, the elements may be made in the shape of numerals so that various combinations of numerals or numerals and letters may be fit together into a discontinuous spherical design.
