Who Wants Pizza?

All the children are going to share the pizza. We will cut enough pieces so each child can have one, and the pieces should all be the same size.

In math, we call each piece a fraction of the whole pizza.

How to Make a Fraction

Take an object like the blue box.

 

 
Divide it into equal parts.

 
   
   

 
Let's color one of the parts red.

 
   
   

Now we can write the fraction of the box that is red.

4
= red part
