ABSTRACT:
An educational aid for word and numeral recognition including a baseboard and sets of cards positionable on the baseboard in aligned relation to enable a student to recognize numerals, the value of such numerals and the definitive word for such numerals. Each card is a relatively large, rigid panel having a numeral, the definitive word for the numeral and distinguishable colored dots indicating the value of the numeral on one side with the obverse side of each card eliminating the colored dots to provide a more advanced educational aid. The baseboard includes a pair of stationary symbols indicating the action or manipulation for the numerals indicated onto adjacent cards and the result of such manipulation or action between a second and third card with the first two cards indicating the problem and the third card indicating the solution to the problem. The symbol between the cards indicating the problem is reversible and interchangeable to indicate various mathematical actions or manipulations with respect to the numerals on the two adjacent cards indicating the problem. The cards include notches receiving the upwardly projecting symbols on the baseboard to retain the cards in alignment with each and the baseboard is provided with an edge flange and a recess in an opposite edge to facilitate positioning of the cards and enabling the cards to be more easily picked up and placed in position on the baseboard.
