Cuisenaire
Rods

Manipulatives
and More

Cuisenaire rods are often used in the elementary school classroom. Shown below are a few problems that illustrate their usefulness.

**Factors &
Multiples**

A row of rods of the same color is called a *one-color
train*. Here is a one-color train that represents the number
12.

- What other rods can be used to form a one-color train for 12? What information do these provide?

- How many different one-color trains are possible for any given prime number?

- If an all-purple train is the same length as an all-yellow train, what can be said about the number of purple rods?

- What is the smallest number of light green rods for which an all-green train has the same length as an all-black train?

**Fractions**

- If the brown rod represents one unit, what is the length of the red rod?

- What fraction is represented by the red rod if the yellow rod is the unit rod?

- What is the unit rod if the purple rod represents 2/5?
