**Learn Fractions with Cuisenaire
Rods**

### Identify the Numerator and Denominator

The standard method of showing fractions with
the cuisenaire rods is by placing one rod beside the other to show how
they compare in size. The rods can be shown vertically (as below) or horizontally.
The first rod of the ordered pair is the **numerator ( **the top number
of a fraction)**.** The second rod of the ordered pair is the **unit**
or **denominator (**the bottom number of a fraction)**.**

FOR EXAMPLE:

** = 1/2 = 2/3**_{ } = 4/3_{ }= 3/2

**Now you give it a try: **

On your own paper, write the fraction
represented by each of the following.

**1. = 2. =**

**3. = 4. =**

**5. =**

**Check your Answers.**
