Meet Lily! Today is her birthday, and she has a yummy carrot cake to share with her seven friends. Lily wants everyone to get the same amount of cake, so she needs to use something called fractions. But what are fractions, and how do they help Lily share her cake?
A fraction is a way to show equal parts of a whole thing. It has two parts: the numerator and the denominator. The denominator is the bottom number, and it tells us how many equal parts the whole thing is divided into. The numerator is the top number, and it tells us how many parts we have.
Now, let’s see how Lily uses fractions to share her cake. She cuts the cake into eight equal pieces. This means the whole cake is divided into eight parts. Lily keeps one piece for herself and gives the rest to her friends. How much cake does Lily have? We can write this as a fraction!
The whole cake has eight pieces, so the denominator is eight. Lily has one piece, so the numerator is one. We write this as 1/8, which is called one eighth.
Let’s look at another example with party hats. There are five party hats in total. Some have spots, and some have stripes. How many hats have spots? Three! So, the total number of hats is five, which is the denominator, and the number of spotty hats is three, which is the numerator. We write this as 3/5, or three fifths.
Now, how many hats have stripes? Two! We write this as 2/5, or two fifths.
We use fractions all the time, even when we don’t realize it. When we share chocolates, pizza, or fruit, we are using fractions to make sure everyone gets an equal share. Fractions help us share things fairly, just like Lily did with her cake!
Now, everyone at Lily’s birthday party can enjoy a fair share of the delicious carrot cake!
Fraction Hunt: Go on a fraction hunt around your home or classroom! Look for items that can be divided into equal parts. For example, a pizza, an apple, or a chocolate bar. Try to divide these items into equal parts and write down the fractions you create. How many different fractions can you find?
Build Your Own Fraction Pizza: Use paper or cardboard to create your own pizza. Cut it into different numbers of equal slices, like 4, 6, or 8. Decorate each slice with toppings like paper pepperoni or mushrooms. Share your pizza with friends or family and write down the fractions for how many slices each person gets. Can you make sure everyone gets an equal share?
Fraction Story Time: Create a short story or comic strip about a character who uses fractions in their daily life. Maybe they are sharing a basket of apples with friends or dividing a garden into sections for planting. Draw pictures and write about how they use fractions to solve problems. Share your story with the class!

[Music] This is Lily. It’s her birthday today! She has bought an amazing carrot cake for her birthday party to share with her seven friends. Lily wants to share her birthday cake equally so it’s fair for everyone. But how can she do this using fractions?
What is a fraction? A fraction is an equal part of a whole. A fraction has two parts: a denominator and a numerator. The denominator is the bottom number in a fraction; it represents the total number of equal parts that the item has been divided into. The numerator is the top number in a fraction; it represents the number of equal parts of the item that you have.

Okay, time to put this all together! Lily’s birthday cake has been cut into eight pieces. This means there are eight equal parts of a whole cake. Lily keeps one piece for herself and gives the rest away to her friends. How much of the cake did Lily get? Let’s write it as a fraction.
First of all, how many pieces made up the whole cake? That’s right, eight! Now, how many cake pieces did Lily get? One. So the total number of pieces that the cake was divided into was eight, which is the denominator, and the total number of parts Lily got was one, which is the numerator. We can write this as one over eight. This is also known as one eighth.
Let’s look at fractions in a slightly different way. Here are some of the party hats for Lily’s birthday party. There are five in total. [Music] Some have spots on them and some have stripes. How many out of the five party hats have spots? Three. The total number of party hats we have is five, which is the denominator, and three of the party hats have spots, which is the numerator. We write this as three over five, or three fifths.
How many party hats have stripes? Two. [Music] This can be written as two over five and said as two fifths. We share things all the time, like our chocolates, pizza, and fruit, which means we are constantly using fractions without even realizing it. Fractions help us to share things equally. Now nobody at Lily’s birthday party will miss out on that delicious carrot cake!
