Abstract: The educational math toy includes various embodiments, each having a triangular configuration. The toy is based upon the concept that two numerical factors will always provide a solution when manipulated by a mathematical operation, with the two factors being shown at two corners and the solution being shown at the third corner of the triangle. One series of embodiments includes variations on a mechanical device containing a central idler gear and a series of three outer gears arranged in a triangular array in a housing. The gears, or interchangeable display discs used therewith, rotate in registry, with each displaying one of a series of numbers through corresponding windows in one or both faces of the housing. The monolithic tiles are arranged in the same manner, but display only one fixed set of factors and one solution on each face. Braille may be used in lieu of numbers, if so desired.

The methods of establishing a time of day operate independent of each other, allowing for a student to match one method to the other.

Abstract: The present invention is directed to a system for demonstrating mathematic concepts, such as fractions and their equivalents. The system includes at least one device constituted by a pie chart sheet having a slot, and a rotating disk having a slit. The slit in the rotating disk provides a leading edge which is inserted through the slit on the chart page to allow the rotating disk to cover any selected portion of the chart. Because the cuts in both the pie chart on the chart sheet are radial, rotation of the disk about a common center point is facilitated.

Abstract: A spinning wheel type paper product and a method of fabricating the same from a single continuous web of material. The method comprises the steps of cutting the web of material to define a window and a wheel having a central aperture and slitting the web into two ribbons, one of the ribbons including said window and the other including said wheel. An area of glue is applied to the ribbon carrying the window at a location spaced apart from the window and the ribbons are stacked in a position for aligning the central aperture with the glue area. The ribbon carrying the window is folded over so as to enclose the ribbon carrying the wheel and such that the area of glue extends through the central aperture in the wheel to adhesively secure, with a facing surface of the window carrying ribbon, the other side thereof. Individual products are then formed by transversely cutting the web.

Abstract: A demonstrative teaching apparatus for teaching the relationship between variable pictorial and/or graphic displays and their respective numerical values, in which the entire apparatus is positioned within an apparatus housing. The apparatus housing incorporates viewing areas on its front and rear sides so as to provide optical display of the relevant teaching portions of the apparatus. The front viewing area reveals the position of the segmented display while the rear viewing area reveals numerical indicia corresponding to the display of segments appearing through the first viewing area. The segmented display and, in turn, its respective numerical indicia, can be increased or decreased by forward or reverse rotation of a circular disk. The circular disk is precluded from excessive rotation in either direction through stopping mechanisms which limit the inadvertent winding or unwinding of the segmented display.

Abstract: An educational device comprises an outer cylinder and an inner cylinder within said outer cylinder. The inner cylinder has an end extending from the outer cylinder and is rotatable and axially movable with respect to the outer cylinder. The inner cylinder has a series of multipliers (for example) peripherally arrayed around the end extending from the outer cylinder. The outer cylinder includes a series of windows and a series of multiplicands peripherally arrayed around the end from which the inner cylinder extends such that each of the multiplicands can be aligned with each of the multipliers by rotating one of the cylinders. The inner cylinder further includes rows of products physically arranged relative to the windows so that the products do not appear in the windows when the inner cylinder extends from said outer cylinder but do appear in the windows when said inner cylinder is inserted into said outer cylinder so as to display the product of the selected multiplier and multiplicand.

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.

Abstract: An educational game system wherein a random selector of mathematical problems is used in playing various popular board games, simultaneously providing drill in the multiplication tables. Players must determine missing answer numbers which then dictate game piece movements. Appropriately formulated problem sets, together with dice doubles indicia, permit the random selector device to substitute for dice, spinners, and other random selection means normally used in these games. Changeable problem sets provide drill in particular multiplication tables. Usage procedure facilitates table memorization. The problems each have a missing number in which the majority are not full two digit numbers but the first or second digit of the product or one of the factors. The average value of the missing numbers for a set being less than ten. Five embodiments are disclosed, employing different random selection devices.

Abstract: A spinner having easily changeable indicia and an upper section which can be turned for viewing the indicia from different directions. The indicia are printed on two-sided, symmetrically shaped cards, each having a large hole in the center and evenly spaced notches along its outer edge. A card is mounted by placing it on top of the device. The central hole accommodates the spinner's pointer, allowing disks to be changed without removing the pointer. When a disk is mounted, some of its notches mate with raised tabs on the upper section, holding it in place. The remaining notches permit access to finger notches in the upper section which facilitate turning it, in a fashion similar to telephone dialing. When the upper section is turned, the spinner's pointer turns together with the indicia.
