The tubular members may be circumferentially configured in any geometric shape, and may consist of any variety of colors; and the tubular members may be imprinted or decalled with numeric, alphabetic, or logotype designations, all of which enhance the educational experience that results from use of the invention.Type: GrantFiled: March 6, 1989Date of Patent: January 9, 1990Inventors: Dorothy M. Brown, John S. Brown

Patent number: 4838794Abstract: A metric block toy comprising ten blocks of varying colors, each block being a one tenth of a meter cube, and having indicia designating ten centimeter increments along one edge of each block, together with other legends designating the length of the edge invarying metric terms. The blocks, when placed in aligned relation, indicate the total length of one meter.Type: GrantFiled: June 16, 1988Date of Patent: June 13, 1989Inventor: Lyman Coddington

Patent number: 4812123Abstract: An educational device useful for teaching numbers, addition, subtraction, reading, and logic comprising a flat playing surface having rows of equally dimensioned boxes, ascending numerical indicia associated with the boxes in each horizontal row, blocks of varying dimensions having numbers thereon proportional to their relative horizontal dimensions and being adapted to fit in each row in such a way that the number appearing to the right of the block or block will indicate how may boxes are covered by the block or blocks in that row. In a preferred embodiment there is also provided a set of card containing a numbered card corresponding to each numbered block.Type: GrantFiled: July 16, 1987Date of Patent: March 14, 1989Inventor: Roy D.

Patent number: 4713009Abstract: A teaching apparatus for Mathematics, specifically algebraic concepts for very young children, enables 3rd and 4th grade level students to solve simple linear algebraic equations. The apparatus includes easily manipulated elements which serve as cognitive reinforcement during the learning process. These physical elements are used in conjunction with a set of rules or "legal moves". The apparatus and corresponding legal moves determine a physical model and physical process to represent both an algebraic linear equation and its algebraic solution. A simple physical element, such as a pawn, is used to denote the unknown quantity. Numbered cubes are used to represent numerical values. These elements are color coded to represent both positive and negative values of the quantities represented. By the use of this apparatus and associated legal moves, students learn to simplify a given linear algebraic equation to the point where the solution or value of the unknown quantity is intuitively obvious.Type: GrantFiled: June 11, 1986Date of Patent: December 15, 1987Inventor: Henry Borenson

Patent number: 4637798Abstract: Disclosed is a doll which is useful as a child's plaything, useful for teaching the child to count from 1 through 10, useful for teaching the child to identify colors, and useful to familiarize the child with various wearing apparel fasteners. The doll includes at least 10 groups of distinctive features with each group being made up of a predetermined number of similar features, the predetermined number being one of the numbers from 1 to 10, so that each number from 1 to 10 is represented by at least one such group. The doll further includes a number of distinctly colored areas and a number of different wearing apparel fasteners.Type: GrantFiled: November 2, 1984Date of Patent: January 20, 1987Inventor: Mary L. MaidenNesset

Patent number: 4634385Abstract: 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.Type: GrantFiled: December 16, 1985Date of Patent: January 6, 1987Inventor: Virginia Stemper

Patent number: 4585419Abstract: The instant invention relates to an aid for the carrying out of a didactic game in order that any (n) based number system may be learned.It consists of a series of containers decreasing in size, each containing an (n) number of smaller containers which are equal to each other; the smallest container holds an (n) number of pieces each representing a numerical unit. A desk is provided with colored squares or frames arranged in such a way that the last square (frame) on the right is of the same color as the unit of the first order, the penultimate the same color as the unit of the second order and so on.Type: GrantFiled: November 20, 1984Date of Patent: April 29, 1986Inventor: Maria P. S. Rinaldelli

Patent number: RE34498Abstract: An arithmetic teaching device consisting of a rod having hand movable spaced collars slidable thereon and having sequentially spaced numbers therealong corresponding to the collars whereby the numbers indicate visually the arithmetic calculation of preceeding manipulated numbers.Type: GrantFiled: October 20, 1992Date of Patent: January 4, 1994Inventor: Howard M.
