# 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. =`
