What each level generates

Grade 3 equivalent fractions — the exact skill behind each difficulty setting, straight from the generator.

  1. Level 1Missing numerator
  2. Level 2Simplify to lowest terms
  3. Level 3Both directions

Grade levels follow the progression common to most English-language curricula — not one specific national curriculum. Every level shows exactly what it generates, so you can check the fit with your own program. See the full scope & sequence →

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.
