Grade 3 Fractions Worksheets — Unit Fractions & Equivalence PDF
Grade 3 is the year fractions become numbers in their own right: unit fractions like 1/3 and 1/6, and the first look at equivalence. This generator covers both, on separate sheets — Fraction of a Number starts from unit fractions of a quantity, and Equivalent Fractions asks for the missing number, first scaling up and then simplifying back down — alongside comparing, ordering, and adding and subtracting fractions that already share a denominator. Comparing and ordering both stay inside what Grade 3 is actually taught, which is fractions that share a numerator or a denominator: Comparing Fractions runs from the same denominator to the same numerator and then weighs each fraction against one half, and Ordering Fractions opens with a same-denominator set built around one unit fraction, put in order greatest to least, then moves to a set of unit fractions and on to any set sharing a numerator. Neither ever asks for a common denominator — that is Grade 4 work, and it is left to Grade 4. Every control updates the preview instantly, and the shareable link reproduces the identical worksheet and answer key.

Each one generates a different kind of question, with its own three levels and answer key.
- Fraction of a NumberFind a fraction of a whole amount, like 1/4 of 12.
- Equivalent FractionsFill in the missing number that makes two fractions equal.
- Comparing FractionsDecide which fraction is greater using <, > or =.
- Ordering FractionsPut a set of fractions in order from least to greatest.
- Adding Like FractionsAdd fractions that already share a denominator.
- Subtracting Like FractionsSubtract fractions that share a denominator.
What each level generates
Grade 3 fraction of a number — the exact skill behind each difficulty setting, straight from the generator.
- Level 1Unit fractions, small numbers
- Level 2Non-unit fractions
- Level 3Find two fractions, then combine

The Grade 3 fraction milestones
Most Grade 3 curricula expect students to understand a unit fraction as one part of a whole split into equal parts, find unit fractions of quantities, recognise simple equivalents such as 1/2 = 2/4 = 3/6, and compare two fractions only when they share a denominator or share a numerator. The Fraction of a Number sheet here drills the first skill; Equivalent Fractions drills the second; Comparing Fractions keeps to exactly those two cases and adds the one-half benchmark. Every denominator on these pages comes from the family Grade 3 works in — halves, thirds, quarters, fifths, sixths, eighths and tenths — so nothing on the sheet needs a common denominator to be found first. That step belongs to Grade 4 and has its own pages there.
A realistic benchmark by year-end: finding 1/4 of 20 or 1/5 of 35 confidently, spotting that 2/6 equals 1/3 without prompting, and knowing that 3/8 is less than a half because 4 eighths would be the half. Speed matters far less than being able to explain why — "1/4 of 20 is 5 because 4 fives make 20" ties fractions to the division and multiplication facts being learned in parallel.
Building a practice routine
Ten problems a day on Fraction of a Number, three or four days a week, is a solid rhythm. Watch for the classic Grade 3 error: dividing by the numerator instead of the denominator (answering 1/3 of 12 with 4 is right; answering 1/3 of 12 with 36 means the child multiplied). When that error disappears for a week, add the Equivalent Fractions sheet twice weekly. On Comparing Fractions the error to expect is the same-numerator one — reading 3/8 as bigger than 3/5 because 8 is bigger than 5 — and it is worth a drawn picture rather than a rule.
Use Shuffle to get a brand-new set at the same settings each day, and keep one fixed sheet — the link stores it exactly — as a fortnightly re-test to make progress visible. The answer key prints on its own page, so checking takes a minute.
Frequently asked questions
▸What fractions should a Grade 3 student know?
Unit fractions (1/2, 1/3, 1/4, up to about 1/8, plus tenths), finding unit and simple non-unit fractions of small quantities, and equivalences like 2/4 = 1/2. Comparing is limited to pairs that share a denominator or share a numerator, and to judging a fraction against one half. The sheets here keep to that range, except that the equivalence sheets also use larger denominators such as 12, 16, 24 and 30.
▸How does the Equivalent Fractions sheet work?
Each problem shows a fraction pair with one number missing — for example 1/2 = ?/8 — and the pairs are generated so the missing value is always a whole number. Level 1 scales up, so students find the blank by spotting what the known parts were multiplied by. Level 2 runs the pair the other way, from 8/12 back down to 2/3, and level 3 mixes both directions.
▸Do the Grade 3 sheets ever compare fractions with different denominators?
Only in two easy cases. Comparing fractions with unrelated denominators usually means finding a common denominator first, which is Grade 4 work and has its own sheets there. Grade 3 here compares and orders same-denominator sets, same-numerator sets (3/5 against 3/8, or unit fractions), and single fractions against one half, none of which needs a common denominator.
▸Does the worksheet come with an answer key?
Yes — tick the answer key box and a numbered key prints on a separate final page, so you can keep it aside while your student works.
▸Can I get new problems without changing my settings?
Press Shuffle. You get a fresh set at the same grade, skill, level and question count, and each shuffled sheet gets its own link you can bookmark or share.
▸What age is Grade 3 fraction work for?
Typically 8–9 year olds, but the three levels inside each skill mean you can hand the same page to a younger child ready to stretch or an older one who needs review.
