The rods provide a continuous model of numbers rather than a discrete one. Students can assign a value to one rod color and determine the values of the others by using relationships between the rods. For example, when the white rods are assigned a value of two, the orange rods, which are ten times as long, have a value of twenty. Activities with the rods can help students explore concepts such as whole numbers, basic arithmetic, measurement, symmetry, and patterns, to name a few. The kit also contains a brief introductory pamphlet on learning with the rods.
Kits come in either wooden or plastic rods.
