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 help students explore concepts such as whole numbers, basic arithmetic, measurement, symmetry, and patterns, to name a few. The kit also contains a brief pamphlet that shows how to build with Jumbo Rods.
Kits come in either wooden or plastic rods.
ENC does NOT distribute this resource. Catalog describes Teacher set of jumbo rods as having 56 rods and classroom set of jumbo rods as having 154 rods with self-sorting tray. ENC only has the teacher set in its Repository.
