A method and device for teaching mathematics comprises a plurality of elongated members used to teach mathematics concepts. Each of the plurality of elongated members represent an associated numerical value. 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 the numerical value represented by the elongated member. A plurality of retention members configured to receive the elongated members. Each of the plurality of retention members is configured to receive at least two of the plurality of elongated members. The device also comprises a numberline associated with the plurality of retention members. When the elongated members are placed on the retention member, various mathematical concepts may be shown.
