About This Resource
What is this resource?
This printable maths worksheet is designed to help children build confidence with subtraction by 10s. It focuses on taking away multiples of 10 within 100, using friendly numbers that end in zero.
Instead of just answering standard sums, children will tackle varied missing-number problems. They will solve calculations like:
- 80 − 50 = □
- 100 − □ = 60
- 70 − □ = 40
This resource is ideal for Year 1 and Year 2 pupils who are ready to move beyond basic single-digit subtraction. If your class is working on early numeracy, you can explore more of our KS1 Resources to support their learning step by step.
What will children learn?
Working with multiples of 10 helps young learners spot patterns in numbers. When children practise subtraction by 10s, they realise that the ones digit stays as zero while the tens digit changes. This connects directly to their known number bonds to 10 (such as 8 − 5 = 3 leading to 80 − 50 = 30).
By filling in the missing boxes, pupils also learn how addition and subtraction fit together. Working out what number is missing encourages flexible thinking and deepens their mental maths skills. It naturally supports the UK National Curriculum aim for Key Stage 1 children to subtract multiples of ten and use related number facts up to 100.

Practical tips for home and the classroom
Here are a couple of simple ways to get the most out of this worksheet:
- Use real objects or base-ten blocks: Grab bundles of 10 pencils, Lego bricks grouped in tens, or 10p coins. If a child is stuck on 70 − □ = 40, lay out 7 bundles of ten. Ask them how many bundles they need to remove to leave 4 bundles behind. Seeing the quantities makes the calculation click.
- Count back using a 100 square: A classic 100 square is a wonderful visual aid. Show your learner that jumping up one row means taking away 10. For a question like 80 − 50, they can start at 80 and make 5 easy jumps of ten up the grid to land on 30.
This printable makes a great morning starter, independent desk task, or a quick, calm homework activity. If your learners enjoy this type of challenge, browse our collection of Year 2 Maths Worksheets or pair it with some reading practice from our KS1 Literacy Resources.
You are doing a brilliant job supporting your young learner, and watching their maths confidence grow is always worth celebrating!

❓ Frequently Asked Questions
Q: Who is this worksheet best suited for?
This sheet is designed primarily for Key Stage 1 pupils in Year 1 and Year 2. It is ideal for children aged 5 to 7 who already understand basic subtraction facts and are ready to work with numbers up to 100.
Q: How do the missing-number boxes help my child?
Missing-number sums encourage children to think about how numbers relate to each other rather than just counting backwards. Solving equations like 100 − □ = 60 helps build early problem-solving skills and reinforces the link between addition and subtraction.
Q: Do children need to use column subtraction for these sheets?
No, these problems are meant to be solved mentally or with simple visual aids like number lines, 100 squares, or tens rods. The aim is to help children spot patterns with multiples of ten rather than using written column methods.
