About Year 2 Number Bonds to 20 Worksheets
Can your child add and subtract within 20 confidently? These free Year 2 number bonds to 20 worksheets extend your child's mental maths skills beyond 10. Once your child knows their bonds to 10, moving to 20 is the natural next step — and these worksheets make the transition smooth.
This week's five worksheets take your child through number bonds to 20 using a range of strategies. From number bonds to 10 revision and extending to 20, to double facts, the making 10 strategy, adding three numbers, and subtracting within 20 — your child will build a powerful toolkit for mental arithmetic.
What's Inside Each Day
1
Day 1
Number bonds to 20 — your child revises bonds to 10 and extends to bonds to 20, working with fact families and adding and subtracting across 10.
2
Day 2
Making 10 strategy — children use ten frames, double facts, and near doubles to add within 20, learning to 'make 10 first' as an efficient strategy.
3
Day 3
Adding three numbers — your child adds three numbers together, finding missing numbers and looking for pairs that make 10 to add efficiently.
4
Day 4
Subtracting within 20 — children break numbers down to subtract (e.g. 14 - 6 = 14 - 4 - 2) and use number bars to visualise subtraction.
5
Day 5
Mixed bonds to 20 — inverse operations, adding three numbers, and multi-step word problems bring all the week's strategies together.
Skills Your Child Will Practise
- Extending number bonds from 10 to 20
- Using the 'make 10' strategy for addition
- Applying double and near double facts
- Adding three single-digit numbers
- Subtracting within 20 by breaking apart numbers
- Using inverse operations to check answers
Top Tip for Parents
The 'make 10' strategy is incredibly powerful. When your child needs to add 8 + 5, encourage them to think: "8 needs 2 more to make 10, then add the remaining 3 — that's 13!" Practise this at home with real objects, and you'll see their mental maths speed up enormously.
