Are you ready?

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 answer the following questions.

  1. This shape has $\editable{}$ equal parts.

  2. If one part was shaded, that shaded part would be $\frac{\editable{}}{\editable{}}$​ of the whole.

question 1

Which fraction is larger?

  		1.
    $\frac{2}{4}$24​
    A
    $\frac{3}{4}$34​
    B

This video looks at comparing fractions with larger denominators using area models.

question 2

Which fraction is smaller?

  		1.
    $\frac{3}{6}$36​
    A
    $\frac{4}{6}$46​
    B

 

Remember!

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.

Outcomes

3.NF.A.3

Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.

3.NF.A.3d

D. Compare two fractions with the same numerator or the same denominator by reasoning about their size. Understand that comparisons are valid only when the two fractions refer to the same whole. Record results of comparisons with the symbols >, =, or <, and justify conclusions.
