Equivalent Fractions Worksheets — KS2

The UK National Curriculum introduces equivalent fractions in Year 3, where children recognise and show equivalent fractions using diagrams. Year 4 adds adding fractions with the same denominator. By Years 5 and 6, pupils must identify common factors for simplification, compare fractions with different denominators, and convert between fractions and decimals. Our worksheets provide scaffolded practice at each of these stages.

Our equivalent fractions worksheets include fraction walls and bar models (visual representations), find-the-missing-number problems (e.g. 3/4 = ?/12), simplifying fractions to their lowest form, comparing and ordering fractions with different denominators, and word problems requiring equivalence to solve. Each worksheet increases in difficulty through three levels: foundation, core, and challenge.

Children often think that adding the same number to numerator and denominator creates an equivalent fraction (e.g. 1/3 → 2/4). This is incorrect — equivalence works through multiplication or division. Our worksheets include activities that deliberately address this misconception, showing children why 2/4 ≠ 1+1/3+1 and reinforcing the multiplicative relationship. The answer keys highlight where errors are most likely to occur.
