Grade 3 Fractions Worksheets — Free Printable PDF
Free Grade 3 fractions worksheets — unit fractions, fractions on a number line, equivalent fractions, comparing fractions. Common Core 3.NF aligned.
Fractions are the moment maths stops being about counting and starts being about ratio. A Grade 3 child who's used to whole numbers suddenly meets the idea that 3/4 and 6/8 are the SAME number, just written differently. That's a real cognitive shift, and it's where maths anxiety often starts. The fix is to introduce fractions visually first, with a lot of pictures, before any symbolic manipulation.
Our Grade 3 fraction sheets follow the Common Core 3.NF sequence: unit fractions (the building blocks), fractions on a number line (the breakthrough representation), equivalent fractions (visually first, then numerically), and comparing fractions with the same numerator or same denominator. Every sheet includes plenty of bar models and circle diagrams.
These pair with our Fractions Frenzy game. Don't rush to mixed numbers and operations — those are Grade 4. Build a rock-solid Grade 3 foundation first. Free, no signup, classroom use welcome.

Frequently Asked Questions
What's a unit fraction?+
A fraction with 1 as the numerator — 1/2, 1/3, 1/4 and so on. They're the building blocks of all other fractions.
Why fractions on a number line?+
The number line shows that fractions are numbers (just like whole numbers). Common Core 3.NF.A.2 makes this explicit because it prevents the misconception that fractions are 'parts of a thing' rather than numbers.
Should Grade 3 add fractions?+
No — fraction addition starts in Grade 4 (with same denominators). Grade 3 focuses on understanding what a fraction IS.
What about decimals?+
Decimals don't appear until Grade 4 (4.NF.C.6). Grade 3 sticks to fractional notation.
