ABSTRACT:
A novel educational toy is provided which comprises, in combination, an elongated support rod and a plurality of separated magnetic members slideably received on the rod. Each member has a pair of opposed faces, the faces having an opposite polarity to each other, and the members are arranged on the rod so members of separate groups are magnetically attracted to one another, while each group repels adjacent groups, so that groups are effectively spaced along the rod. Each magnetic member bears identifying indicia, the members of each group also collectively providing separate distinct group indicia. The member indicia may be symbols, numbers, letters, or the like. Alternatively, they may be configurations for the members which resemble solid objects.
A handle may be provided for moving the entire toy. The members can be easily aligned with each other by means of for example, matching detents on adjoining faces, and/or tabs to facilitate handling thereof. The rod may be in a hoop configuration, or in a square or a straight length, and a plurality of rods can be employed to form a ladder or abacus configuration or the like. The toy is simple, inexpensive, and durable, and is capable of teaching physical dexterity, letter combinations, etc., to form words, simple mathematical computations and other relationships, while amusing the child user.
