What to practise

  • Start with confidence-building questions, then increase speed.
  • Use retrieval cycles across the week to avoid forgetting.
  • Pair this page with related year-topic pages to broaden transfer.

Teaching tips

  • Teach subtraction as both take-away and difference.
  • Use number lines for confidence before formal written methods.
  • Practise inverse checks with addition to improve accuracy.

Practice plan for this route

At this stage, children step into KS2, where times-table facts and inverse operations matter more. For this topic, subtraction practice should connect take-away, difference, and inverse addition, so the best practice is short, specific, and repeated across the week.

Skill ladder

  • Start: Use known facts first, then connect multiplication, division, and larger-number questions.
  • Build: count back from small numbers, then find the difference on a number line, then check with addition.
  • Stretch: Move on when the child can choose a strategy rather than copy a fixed pattern.

Example questions

13 - 6 = ?
42 - 20 = ?
71 - 28 = ?

Confidence checks

  • Look for flexible use of times tables, inverse checks, and written working for multi-step questions.
  • Ask the child to explain one answer out loud before chasing faster scores.
  • Return to this route after 24 hours and again later in the week to check retention.

How to work it out

Step-by-step worked examples to talk through together.

13 − 5 = ?

  1. 1 Start at 13 on a number line
  2. 2 Count back 5 steps
  3. 3 Land on 8 — the answer is 8

52 − 27 = ?

  1. 1 Subtract the ones: 12 − 7 = 5 (exchange needed)
  2. 2 Subtract the tens: 40 − 20 = 20
  3. 3 Combine: 25

Quick tips for parents & teachers

  • Use a number line until the child is confident enough to work mentally.
  • Link subtraction to addition — "What do I add to 27 to reach 52?"
  • Keep sessions short and reward accuracy before pushing for speed.
