Introduction to Fractions [WIDA 4-5]

1. Where can you find fractions?

Fractions are everywhere. They show parts of a whole. Anything that has equal parts can show a fraction.

Fractions are in the kitchen. You can find them when you are cooking.

If you need to use one-fourth of a cup in a recipe.

One-fourth is a fraction because it shows one out of four equal parts.

Fractions are in the park. You can find them when you are having a picnic.

If you need to share one-half of a sandwich with a friend.

One-half is a fraction because it shows one out of two equal parts.

Fractions are in the store. You can find them when you are shopping.

If you need to buy something that costs one-quarter of a dollar, or 25 cents.

One-quarter is a fraction because it shows one out of four equal parts (4 x 25 = 100).

What do "Equal Parts" mean?

Equal parts have equal size.

One-half

Do both pictures below show equal parts?

Hint: count the squares.

Activity: can you find the fraction in each picture?

Guess why each picture has a fraction.

The ball is a fraction because it shows 13 equal parts of a whole.

2. How can you make fractions?

Fractions show equal parts of a whole.

You can make a fraction with paper, or other material. To make one half, first find paper. Second, fold the paper into two equal parts. Finally, shade one part. This shaded part shows one-half, which is a common fraction.

How to make one half.

Activity: draw a picture of one-fourth.

Imagine your friend will share a cake with four friends. She will need to cut the cake into four equal pieces. Each piece will be one-fourth of the cake. Pretend a sheet of paper is the cake. How many ways can you draw four equal parts?

3. How can you read and write fractions using numbers?

Remember, each part of a fraction has the same size.

A fraction names part of a whole. So, a fraction has two numbers. One number goes on top, and another number goes under it. A line separates the two numbers. The bottom number shows how many pieces are in the whole. The top number shows how many pieces you are talking about. Below, the top number shows the shaded parts. The bottom number shows all of the parts.

How to read a fraction.

Here are some more common fractions. We will learn to compare, add, and subtract them.

Check your understanding.

4. Exercise

1. Find a flag with a fraction.

Draw the fraction you see in the flag:

Why does the flag have a fraction?

Model sentence: The pizza has a fraction because it shows 8 equal parts of a whole.

Word Bank: [because] [parts] [of a] [equal] [flag]

The flag has a fraction __________ it shows __________________________.

2. Draw your own fraction. Any fraction.

Why does it show a fraction?

Model sentence: The pizza has a fraction because it shows 8 equal parts of a whole.

Word Bank: [because] [parts] [of a] [equal] [flag]

The drawing has a fraction _________ it shows ________________________.
