The problems may consist of counting, arithmetic equations, time equivalents, and money equivalents.Type: GrantFiled: December 16, 1985Date of Patent: January 6, 1987Inventor: Virginia Stemper

Patent number: 4505682Abstract: 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.Type: GrantFiled: May 25, 1982Date of Patent: March 19, 1985Assignee: Texas Instruments IncorporatedInventor: Barbara J.

Patent number: 4457719Abstract: 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.Type: GrantFiled: May 25, 1982Date of Patent: July 3, 1984Assignee: Texas Instruments IncorporatedInventors: Ashok Dittakavi, Barbara J. Thompson

Patent number: 4378214Abstract: A multi-pocketed washable fabric body portion is employed with several selective reversible fabric strips each having fastener components for engagement with mating fastener components on the body portion. The strips carry colors, shapes, alpha-numeric indicia and material textures requiring recognition by a child. Groups of fabric elements having colors, shapes, indicia and textures to match up with the strips are provided, and a child, after sorting the fabric elements, inserts them in the pockets of the body portion which are positioned adjacent to recognized colors, shapes, indicia or textures on the strips.Type: GrantFiled: January 27, 1982Date of Patent: March 29, 1983Inventor: Marion W.

Patent number: 4372742Abstract: 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.Type: GrantFiled: October 21, 1981Date of Patent: February 8, 1983Inventor: Roland A. L. Wentworth

Patent number: 4358274Abstract: 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.Type: GrantFiled: September 4, 1979Date of Patent: November 9, 1982Inventor: Herbert S.
