ABSTRACT:
A card-holding teaching device especially useful for blind children comprising a stiff body having at least one elongated piece of flexible material extending thereacross, the material having on one side tiny, soft, flexible projections which face the stiff body so that a card with teaching symbols thereon can be easily inserted between the material piece and the body because of the easy yielding of the projections even though they hold the flexible piece away from the body sufficiently for easy insertion by a blind student.
