  • Patent number: 9342995
    Abstract: 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.

  • Patent number: 4772208
    Abstract: An apparatus for teaching mathematics which applies and puts to work in various ways the modern teaching of mathematics for all levels of elementary education through set theory, comprises a horizontal board divided into eleven zones and having two outwardly-projecting subsidiary boards. In use, objects can be placed in selected zones of the horizontal board to demonstrate mathematical operations, and information relating to the operation is written on appropriate zones of the vertical board and on the subsidiary boards. The horizontal board has a bevelled front edge portion on which further information can be written, and two portions in which objects to be placed in the zones of the horizontal board can be placed beforehand.

  • Patent number: 4666163
    Abstract: A card game comprises a set of cards with each card being formed with a slit along its mid-line starting from one edge and extending for about one-half its width towards its opposite edge such as to permit each card to be inserted via its slit into the slit of each other card in the set to form a pair with one-half of one card aligned with and exposed to view with the other half of the other card. Each card has indicia on each half of the card on opposite sides of its respective slit. The indicia on the half of each card on one side of the slit is non-validly complementary with the indicia on the other half of the card on the other side of its slit, but is validly complementary with the indicia on some, but not all, of the other cards of the set to form a valid card pair therewith when the two cards are inserted into each other via their respective slits.

  • Patent number: 4634385
    Abstract: A teaching wheel challenges a student to find the correct answer to arithmetic and other problems. The teaching wheel comprises a problem disk and an answer disk mounted concentrically for rotation on a frame. The problem disk is mounted above the frame, and the answer disk is mounted under the frame. The problem disk has a smaller diameter than the answer disk and frame. The problem disk is divided into a number of sectors, with a problem radiating outwardly in each sector. The answer disk has sectors containing the answers to the problems near the periphery of the disk. The frame is notched to reveal one answer on the answer disk. The problem disk is rotated so a selected problem sector is aligned with the frame notch, and the answer disk is rotated until the correct answer appears in the notch adjacent the problem sector. The problems may consist of counting, arithmetic equations, time equivalents, and money equivalents.

  • Patent number: 4505682
    Abstract: An electronic learning aid selectively provides synthetic speech to an operator. An electro-optic sensor which reads bar code from the pages of a book selects speech words or phrases to be produced by an electronic speech synthesizer. A mode of operation is provided wherein the operator selects an object of comparison such as a displayed picture, number or the like and then seeks to identify one of a plurality of choices which properly associates with the object of comparison.

  • Patent number: 4457719
    Abstract: Disclosed is an electronic learning aid having modes of operation to provide an interesting and effective learning experience to a student. In the preferred embodiment, inputs to the learning aid are effected via scanning of a bar code on a page by the student. In a first mode, the student is audibly directed to place depicted objects on the page in some specific sequence, as by alphabetical order of the first letter of the names of the objects. The student selects items in the sequence by scanning bar code associated with each item and the system audibly informs him of his progress in correctly identifying times of the sequence. In a second mode the student upon scanning the bar code associated with a depicted object is audibly directed to spell the name of that object. The system audibly informs him of his progress.

  • Patent number: 4372742
    Abstract: An arithmetical teaching aid includes a display board B comprising a rectangular array of display areas A arranged in rows R and columns C. Adjacent display areas A are marked (1, 10, 100 etc.) to represent successive powers of an arithmetic base number so that display areas A (where there are more than one) representing a given power of the base number (e.g. 1,000) are arranged diagonally across the board. Means (for example slides S) are provided for relatively moving the various rows R of display areas so that displays (e.g. 1,000) in the different rows R corresponding to the same power of the base number can be brought into columnar registration. All display areas A corresponding to a given power of the base number have a common tonal and/or textural characteristic which is different from the characteristic of each neighboring display area corresponding to a different power of the base number. Such characteristics are preferably provided by three different colors.

  • Patent number: 4358274
    Abstract: A game and teaching device construction is described to include a plurality of indicia bearing blocks bound together by a pair of flexible straps. Each block is generally shaped in the form of a solid rectangle whereby a first strap is affixed to each block at one end thereof and a second strap is affixed to each block at the other end thereof. Each block includes front and back faces with one of such faces bearing indicia, for example a plurality of dots, and the other face bearing indicia of the number corresponding to the number of dots on the first described face. When stretched out, the construction is such that pushing the first block will cause the collapse of it and all other blocks in sequence. Furthermore, the construction can be used such that a child is interrogated to associate a number with the number of dots showing on a particular block, with the other face of the block being used to verify the child's answer.
