If I ate 1 half of the pizza, I could write this as a fraction.
A fraction represents part of a whole. In this case I ate 1 out of the 2 parts.

4. How do I write a fraction?
Half
How do I write a fraction?
When I make my fraction I put the part on top. This is called the numerator.
The number of parts goes on the bottom, this is called the denominator.
So I ate 1 part, so the number 1 goes on top.
There were 2 parts total, so the number 2 goes on the bottom. 1

5. Now Let’s Talk About Thirds!
This pizza is divided into three equal parts.
We call each of these parts a third.
Remember a fraction represents part of a whole.
So if I ate one piece this pizza, I would eat one third of it. We can write this as a fraction.
In the denominator I would put the number 3 because there are 3 pieces total.
In the numerator I would put 1, because I ate 1 piece. 1

6. Now Let’s Talk About Fourths!
This pizza is divided into four equal parts.
We call each of these parts a fourth.
Remember a fraction represents part of a whole.
So if I ate one piece this pizza, I would eat one fourth of it. We can write this as a fraction.
In the denominator I would put the number 4 because there are 4 pieces total.
In the numerator I would put 1, because I ate 1 piece. 1
