Equivalent Fractions & Comparing Fractions Review

Equivalent Fractions

We have learned that fractions are equivalent when the wholes we are comparing are the same SIZE and cover the same AMOUNT.

What are some strategies we can use to help us find equivalent fractions?

• I can draw a rectangular area model for each fraction, making sure the models are the same size.

• I can draw number lines for each fraction to compare the size and amount of the fractional parts.

Let's practice our strategies for finding equivalent fractions.

We will start with a few quick problems to warm up!

Multiple Select

What fractions are represented by the shaded partitions in this model?

• 2/3

• 3/4

• 2/6

• 4/6

Multiple Choice

Which two of these squares have the same amount shaded?

• P & R

• Q & S

• R & S

• P & Q

Multiple Choice

Which of the models represents an equivalent fraction to 2/3 ?

• A

• B

• C

• D

Now that you've got your brain going, let's try a few that are more challenging!

Multiple Choice

Josie and Paul are planting flowers for their flower gardens, which are the same size. Josie plants daisies in 4/6 of her garden.

If Paul has 12 sections in his garden and wants to plant daisies in the same size space as Josie, how many of the sections will he plant daisies in?

• 6/12

• 4/12

• 8/12

• 9/12

Multiple Choice

Multiple Choice

The table shows the fraction of the summer 3 children spent at the beach for vacation.

Which 2 children spent the same amount of time at the beach?

• Joey & Miley

• Miley & Veronica

• Joey & Veronica

Comparing Fractions

What are strategies we can use to compare fractions?

• If they have the same denominator, compare the numerators

• If they have the same numerator, compare the denominators

• Compare to the benchmarks 0, 1/2 and 1

• Draw area models to represent each fraction, remembering the models must be the same size.

• Use fraction number lines to compare the fractions.

Multiple Choice

Complete this statement with the correct symbol: 2/3 _____ 4/6

• =

Multiple Choice

Which statement is true?

• 3/4 = 2/3
