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

  • Start with number bonds to 10 before bridging through 10.
  • Use partitioning (tens and ones) to reduce cognitive load.
  • Mix quick-fire recall with worded examples so transfer improves.

How to work it out

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

7 + 5 = ?

  1. 1 Start at 7 on a number line
  2. 2 Count on 5 steps
  3. 3 Land on 12 — the answer is 12

23 + 14 = ?

  1. 1 Add the ones: 3 + 4 = 7
  2. 2 Add the tens: 20 + 10 = 30
  3. 3 Combine: 37

48 + 36 = ?

  1. 1 Partition: 40 + 8 and 30 + 6
  2. 2 Add tens: 40 + 30 = 70
  3. 3 Add ones: 8 + 6 = 14
  4. 4 Combine: 70 + 14 = 84

Quick tips for parents & teachers

  • Use objects (Lego bricks, counters) for hands-on practice.
  • Practise number bonds to 10 first — they unlock faster mental addition.
  • Praise effort and speed separately to build confidence.
