About This Resource

Practice Addition by 10s with Confidence

Learning to work with larger numbers is a huge milestone for young learners. This printable maths worksheet is designed to give Key Stage 1 children plenty of friendly practice with addition by 10s.

Instead of simple counting, this sheet encourages children to spot patterns and think flexibly about numbers up to 100. By solving a mix of standard questions and missing-number problems, pupils build the essential numeracy skills they need for everyday maths.

Who Is This Resource For?

This activity is ideal for Year 1 and Year 2 pupils (ages 5 to 7) who already understand basic single-digit addition and are ready to take the next step. It is a fantastic fit for busy classroom teachers looking for quick independent work, as well as parents who want to support their child's learning at home.

If you are exploring our wider collection of KS1 Resources, this worksheet slots in neatly alongside your existing weekly maths plans.

What Children Will Learn

This worksheet focuses on adding multiples of 10. Rather than feeling overwhelmed by double-digit numbers, children learn to see how familiar number bonds link directly to tens. For example, if they know that 3 + 4 = 7, working out 30 + 40 = 70 suddenly feels much easier.

On this sheet, children will:

Practise adding two multiples of 10 together (such as 30 + 40 = □).
Tackle missing-number problems (such as 50 + □ = 100).
Strengthen their place value knowledge and recall of number facts up to 100.
Build reasoning skills by working backwards from a total.

Practising addition by 10s in this way aligns naturally with Key Stage 1 maths aims, helping pupils become confident and fluent with mental calculations.

Helpful Tips for Home and School

Here are a couple of quick, practical ways to get the most out of this resource:

Use hands-on items first: Before putting pencil to paper, bring out physical maths aids. Base ten blocks, bundles of ten straws, or even stacks of ten Lego bricks work wonderfully. Seeing five stacks of ten helps children grasp that 50 is just five tens, making the sums on the page make visual sense.
Turn it into a partner game: In class, have children work in pairs. One child can read a missing-number question aloud, while the other uses a 100-square grid to jump along the tens column to find the missing value.

Whether you use this as a morning starter, a plenary check, or a calm homework task, it gives children the regular practice they need to feel proud of their maths skills. You have got everything you need to help your learners shine today!

❓ Frequently Asked Questions

Q: What age group is this worksheet best suited for?

This activity is designed for Key Stage 1 pupils, typically aged 5 to 7 in Year 1 and Year 2. It is ideal for children who are comfortable with basic addition and are beginning to work with two-digit numbers.

Q: How do missing-number questions help my child learn?

Missing-number sums, like 50 + □ = 100, encourage children to think flexibly rather than just memorising answers. They help children understand the relationship between parts and wholes, which prepares them well for subtraction and early problem-solving.

Q: Can I use this worksheet for home learning?

Yes, absolutely! The page is simple and easy to follow, so parents can print it out and use it at home without needing any specialist teaching experience.
