This document introduces fractions by explaining that a fraction represents parts of a whole. It uses examples of pizzas that have been cut into halves, thirds, and sixths to illustrate fractions like one half, one third, and three sixths. The key parts of a fraction, the numerator and denominator, are defined - with the numerator representing the number of parts and the denominator representing the total number of parts that make up the whole.

2. WHAT IS A FRACTION?
A fraction is a number that
tells us parts of a whole.
This is a whole,
one big circle!
These

parts!

3. WHAT IS A FRACTION?
LOOK AT THIS PIZZA! IT’S A
WHOLE PIZZA
This pizza has been cut into
half! It’s now TWO parts. In
fractions we call this “one half”
we write this as 

4. WHAT IS A FRACTION?
LOOK AT THIS PIZZA!
This pizza has been cut into
three equal parts. We call this
one third and write it as 

5. THREE EQUAL PARTS GIVES
US THREE THIRDS. THINK
ABOUT JUST ONE SLICE. WE
CAN WRITE THIS USING A
FRACTION

6. TWO SLICES IS TWO THIRDS.
WE CAN WRITE TWO THIRDS
AS

7. THE TOP NUMBER OF THE
FRACTION TELLS US HOW MANY
SLICES WE HAVE.
WE CALL IT THE NUMERATOR.
The bottom number tells us how
many parts in the whole pizza.
We call it the denominator.

8. WHAT IF YOU HAVE A
CAKE CUT INTO SIX
EQUAL PARTS?
Here are all the fractions you can make.
