4th grade comparing fractions worksheets

Tap to see another sample sheet. The picture follows the difficulty you pick.

Fourth grade removes the guardrails: any two fractions can land in a pair. Your child compares by making common denominators, cross-multiplying, or checking against the benchmark 1/2, whichever route is fastest, and writes <, >, or =.

Free printable PDF worksheet, aligned to Common Core 4.NF.A.2.

Each print is a different sheet with its own answer key. You don't need to sign up.

The kind of problems you'll get

Write <, >, or = to compare each pair of fractions.

  1. 1/3 2/3

    Answer: 1/3 < 2/3

  2. 1/2 3/4

    Answer: 1/2 < 3/4

  3. 2/3 2/4

    Answer: 2/3 > 2/4

Every print pulls a fresh set of problems at this level, so a make-up test or a second sibling never gets the same sheet.

What's on a 4th grade sheet

The sample sheet above has 15 problems. This sheet is aligned to 4.NF.A.2. The 3rd grade sheet is aligned to 3.NF.A.3.d.

Every version prints on US Letter or A4, with its answer key after the problems.

How to teach this

Have your child name a strategy out loud before writing: match the denominators, cross-multiply, or ask "is each more or less than a half?" The benchmark question settles most pairs fastest. When two strategies disagree, that's the error to hunt: redo the pair both ways.

Watch for: Kids pick the fraction with the bigger denominator as the bigger fraction. More parts means smaller parts, so 1/8 is less than 1/3. Kids compare tops and bottoms like separate whole numbers. A fraction is one number, and 1/2 beats 3/8 even though 3 and 8 are both bigger.

Common questions about 4th grade comparing fractions

What's new compared to the 3rd grade sheets?
Any pair of fractions can show up, so matching tops or bottoms is no longer guaranteed. Fourth graders bring a strategy: common denominators, cross-multiplying, or comparing to 1/2.
Do equal pairs really appear?
Occasionally, yes. An = answer like 2/3 and 4/6 checks that your child is comparing values, not assuming every pair has a winner.
