Abstract
An assembly for teaching mathematical concepts includes a plurality of interlocking components, each having at least one connecting end so that the components can be combined in any order or length. Each component is assigned a mathematical value according to its length, and this value may be indicated by indicia on its face or by color coding. A base is also provided for retaining the columns of components in vertical formations. Means are provided on the platform of the base for engaging the bottom component in each column.
