Lesson

Being able to identify how many equal parts are in a fraction model will help us compare fractions in this lesson. Let's try this problem to review.

Here is a shape divided into parts, use it to complete the statements.

a

This shape has ⬚ equal parts.

Worked Solution

b

Each part is \dfrac{⬚}{⬚} of the whole.

Worked Solution

Idea summary

We can write a fraction from a fraction model as:

This video will show us how to compare fractions using models.

Which fraction is larger?

A

B

Worked Solution

Idea summary

To compare fractions using fraction models with the same size pieces, count the number of pieces shaded.

Let's look at finding complements to 1 whole.

If I have 1 third, how many more thirds do I need to make a whole?

Worked Solution

Idea summary

When comparing fractions, if the denominators are the same, then we can compare the numerators. The denominator also tells us how many parts make up one whole.
