Year 1 Number Bonds Games

Year 1 number bonds practice for ages 5-6 with KS1 alignment.

Designed for Year 1 priorities: addition/subtraction fluency and number bonds to 20.

Topic focus within Year 1: instant recall of complement pairs (to 5, 10, 20, 100).

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

  • Use visual pairing first, then move to rapid recall.
  • Connect bonds to both addition and subtraction equations.
  • Revisit mastered bonds weekly to protect retention.

Practice plan for this route

At this stage, children begin turning early number sense into faster mental methods. For this topic, number-bond practice should make complement pairs automatic, so the best practice is short, specific, and repeated across the week.

Skill ladder

  • Start: Begin with known facts within 10, then bridge gently through 10 and 20.
  • Build: show the pair visually, then say the pair aloud, then recall it in missing-number form.
  • Stretch: Move on when answers are accurate and the child can describe the method used.

Example questions

3 + ? = 10
14 + ? = 20
70 + ? = 100

Confidence checks

  • Look for fewer counting-from-one strategies and more use of known facts.
  • 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.

Bonds to 10: 3 + ? = 10

  1. 1 Count on from 3 to 10
  2. 2 3 + 7 = 10
  3. 3 So the missing number is 7

Bonds to 20: 14 + ? = 20

  1. 1 14 is 4 more than 10
  2. 2 10 + 6 = 16… try again: 14 + 6 = 20
  3. 3 Missing number is 6

Quick tips for parents & teachers

  • Use physical objects first (fingers, counters) before moving to mental recall.
  • Say the bond pair aloud together: "3 and 7 make 10" — rhythm helps memory.
  • Once bonds to 10 are solid, bonds to 20 and 100 come much faster.
