Double-sided, front-to-back-aligned, tactile graphic learning aid

摘要

A double-sided, front-to-back aligned tactile learning aid is provided, which includes a substantially planar carrier medium with a protruding front tactile graphic aligned with and symmetrical to a protruding back tactile graphic. The carrier medium may be one, two, or more sheets of paper, plastic, or other generally planar material. The front graphic and the back graphic protrude from the front and back, respectively, of the carrier medium. At least a portion of the back tactile graphic is aligned with at least a portion of the front tactile graphic. The double-sided, front-to-back aligned tactile learning aid is clearly expressive of (and/or representational of) a physical structure, yet is embodied in a generally two-dimensional planar construction, so is easier to store. The double-sided, front-to-back aligned tactile learning aid may be used as a semi-concrete or demi-concrete aid for sighted and visually-impaired students.

主权项

1. A learning aid, comprising:
a plurality of substantially planar carrier mediums, each carrier medium comprising:
a front side;a back side;a front tactile graphic disposed on and protruding from said front side, said front tactile graphic comprising a plurality of first-variation graphics having a first discriminating characteristic, and a plurality of second-variation graphics having a second discriminating characteristic, anda back tactile graphic disposed on and protruding from said back side, wherein said back tactile graphic is aligned with and symmetrical to said front tactile graphic with respect to the carrier medium; wherein each front tactile graphic in said plurality of substantially planar carrier mediums has the same number of total first-variation graphics and second-variation graphics and a different number of first-variation graphics; and wherein the number and specific configuration of said plurality of first-variation graphics and of said plurality of second-variation graphics of said plurality of carrier medium front sides correspond to and represent numerals in different addition or subtraction math facts of a number family.
