ABSTRACT:
An educational and amusement device includes elements in the form of an alphabet and/or the digits of a numbering system. Each character element is similarly divided by a plurality of essentially similar parallel lines, which may consist of a first set of parallel lines alone or first and second sets, with the second set of parallel lines oriented to extend in an opposite and perpendicular direction from such first set of lines. Each element includes at least three parts but less than ten, and preferably is four or five parts for sufficient complexity to maintain interest of a child or other person having a learning disability but of a sufficient simplicity to prevent frustration. Each element may be formed with the parts releasably interconnected with each other as by water soluble adhesive. Each element can be made progressively more complex.
