Abstract: A system uses objects that can be combined to learn mathematical operations. Operand objects illustrate a numerical operand and an associated set of possible numerical solutions to operations performed on the operand number. Operator objects illustrate an operation symbol and a numerical operator. When an operator object and an operand object are combined, a mathematical operation consisting of the operand, the operation symbol and the operator is illustrated, and a solution to the operation is illustrated. The operand objects also include a non-numerical representation of the value of the operand, and the operator objects also include a non-numerical representation of the value of the operator. When combined, the representation of the value of the operator, and the representation of the value of the operand cooperate to represent the value of the solution to the mathematical operation.

Abstract: A bookmarker comprises a thin, planar base member. A thin, planar upper member has the shape of the base member with the perimeter edges of the upper member being permanently adhered to corresponding perimeter edges of the base member. At least two elongate linear slots are formed in the upper member. The slots are parallel with each other and spaced apart. A window opening is provided for each slot. Each window opening is located closely adjacent to a respective slot and between opposite ends of such slot. An elongate, thin slide member is provided for each slot. Each slide member is positioned between the base member and the upper member for sliding motion back and forth along a respective slot. The slide member has a width that spans the respective slot and the respective window opening for that slot. An elongate, raised rib projects from a surface of each slide member so that the rib is received in a respective slot for longitudinal sliding motion back and forth along such slot.

Abstract: A visual aid teaching device for translating one or more superimposed picture images in a linear path at different positions with respect to a stationary underlay picture includes as basic components: a pair of edge strip members, each embodying two or more channel tracks; a transparent, or opaque, rectangular flat surface member snugly mounted on the edge strips through their channel tracks to assemble the body device; sets of layers, each including a stationary underlay picture member and one or more superimposed picture image members. Both members may include algebraic graphs or circles divided into sets of sectors. The layer members can be mounted on the other channel tracks. Algebraic problem solving of compound inequalities in one variable can be demonstrated algebraically along with their graphic solution sets simultaneously by means of translating one or more superimposed graphs at different positions with respect to a set of number line graphs.

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.
