Abstract:
1. A device for teaching mathematics comprising: a) a plurality of elongated members, each of the plurality of elongated members representing an associated numerical value, wherein at least some of the plurality of elongated members are of different lengths, wherein the length of each of the plurality of elongated members is proportional to its associated numerical value, and wherein the elongated members include indicia that partition each elongated member into a number of unit length segments, the number of segments on each elongated member being equal to the associated numerical value; b) at least one retention member configured to receive at least two of the plurality of elongated members, the at least one retention member provided as part of a container configured to store the elongated members, the at least one retention member including a first retention member provided in a base portion of the container and a second retention member provided in a top portion of the container, wherein the top portion is configured to cover the base portion when the container is closed; and c) a numberline associated with the at least one retention member, the numberline including a plurality of numbers and markers, wherein each marker is separated from an adjacent marker by a length substantially equal to the unit length.
