Challenge Questions

1.No — the denominators were not scaled by the same factor.[3]
1. Numerator scale factor: 24 ÷ 4 = 6.
2. Denominator scale factor: 43 ÷ 7 ≠ 6.
3. Because the factors differ, the fractions are not equivalent.
2.No — the denominators were not scaled by the same factor.[3]
1. Numerator scale factor: 24 ÷ 6 = 4.
2. Denominator scale factor: 29 ÷ 7 ≠ 4.
3. Because the factors differ, the fractions are not equivalent.
3.No — the denominators were not scaled by the same factor.[3]
1. Numerator scale factor: 36 ÷ 6 = 6.

Real-life Application

1.15/7 litres = 15/7 (simplified where possible)[3]
1. Each batch needs 5/7 l, so 3 batches need 5 × 3 = 15 lots of 1/7.
2. That is 15/7 litres.
3. Convert to a mixed number if the numerator exceeds the denominator.
2.25/8 litres = 25/8 (simplified where possible)[3]
1. Each batch needs 5/8 l, so 5 batches need 5 × 5 = 25 lots of 1/8.
2. That is 25/8 litres.
3. Convert to a mixed number if the numerator exceeds the denominator.

Critical Thinking

1.Accept any correct response that applies the equivalent fractions rule accurately.[4]
1. Recall the definition that underpins equivalent fractions.
2. Apply it to the values or wording given in the question.
3. State the final answer clearly, with units or terminology where relevant.

Marking scheme

Band	Marks	Descriptor
Mastered	46–54	Applies equivalent fractions fluently, including in unfamiliar contexts, with clear justification.
Secure	35–45	Reliable in routine questions; reasoning is mostly complete.
Developing	22–34	Secure in scaffolded items, inconsistent once support is removed.
Emerging	0–21	Needs re-teaching of the core rule before progressing.

Teacher notes

Set the warm-up as a five-minute starter; it diagnoses readiness for equivalent fractions before you teach.
Guided practice is the pivot point — circulate here rather than during independent practice.
Mark the reasoning questions with the marking scheme bands, not raw totals, so progress is comparable across variants.
Students who band Emerging should repeat the Easy variant of this same subtopic before moving on within Fractions.

Common student mistakes

Adding the same number to both parts instead of multiplying.
Dividing only the numerator, or stopping before the fraction is fully simplified.
Assuming any two fractions with bigger numbers are automatically equivalent.
Multiplying the denominator as well as the numerator when scaling a quantity.
Confusing equivalent fractions with a neighbouring idea in fractions.

Teaching tips

Model one worked example of equivalent fractions under a visualiser before handing the sheet out.
Ask students to predict which question they will find hardest, then check the prediction afterwards.
Pair Developing students with Secure students for the guided practice block only.
Use the answer key as a self-marking station rather than collecting the sheets in.

Extension activities

Challenge worksheet on equivalent fractions with justification-only questions.
Design your own equivalent fractions question and write the mark scheme for it.
Link equivalent fractions to the next subtopic in Fractions and explain the connection.
Ten-minute timed practice to convert accuracy into fluency.
