A synonym for the word "fraction" is "fragment" or "part." A fraction is a part of something. It is less than the something as a whole. If one is a whole, then a fraction is less than one. If an apple is the whole, then a bite of the apple is a fraction.

Graham Cracker

Look at the graham cracker. It has three parts. If you break off one part to eat, you've eaten one third.

You write a fraction like 1/2, 2/6, and 4/8

or

\(\frac{1}{2} \), \(\frac{2}{6}\), and \(\frac{4}{8} \)

In \(\frac{2}{6}\), the 6 represents the whole.
In \(\frac{1}{2}\), the 2 represents the whole.
In \(\frac{4}{8}\), the 8 represents the whole.


You say one half for \(\frac{1}{2}\).
You say two sixths for \(\frac{2}{6}\).
You say four eights for \(\frac{4}{8}\).
You say two thirds for \(\frac{2}{3}\).
You say three fourths for \(\frac{3}{4}\).

When you write \(\frac{1}{2}\), the number 1 is called the numerator and 2 is called the denominator.

Question

In \(\frac{4}{8}\), which number is the numerator, and which is the denominator?

The number 4 is the numerator, and the number 8 is the denominator.
Use numbers to write the following in your Lesson Notes:

1. one half
2. two fourths
3. two thirds
4. one fourth
5. one third
