About This Resource
Are you looking for a simple way to help your child get to grips with their numbers? You are in the right place. At Study Pillars, we know that the jump from counting to ten to reaching twenty can sometimes feel like a big step for little learners.
Our "Write the Missing Numbers 1-20" worksheet is a friendly, no-fuss resource designed to help children bridge that gap. It is clear, easy to read, and gives children the space they need to practise their counting and writing at their own pace.
What is this resource?
This resource is a straightforward activity sheet that focuses on number sequences. It features a series of numbers from 1 all the way up to 20, but there is a catch—some of the numbers have gone for a wander!
Your child’s job is to look at the sequence, work out which numbers are absent, and write them in the empty boxes. By filling in the missing numbers 1-20, children get to see how the number system flows. It is a great way to move beyond just saying the numbers out loud and start actually writing them down in the correct order.

Who is it for?
We have designed this specifically for younger children who are just starting their maths journey. It is a perfect fit for EYFS Activities where children are beginning to explore numbers beyond the basics.
It is also a brilliant tool for Year 1 pupils who are working within the KS1 Resources framework. Whether your child is a confident counter who needs a quick refresher, or someone who finds the "teen" numbers a little bit tricky, this worksheet provides the right level of support.
What will children learn?
Working with this sheet helps children develop several important skills at once:
- Number Sequencing: They will learn what comes before and after a specific number.
- Number Recognition: Seeing the printed numbers helps them identify them quickly.
- Handwriting: Writing the numbers in the boxes is great for fine motor skills and pencil control.
- Confidence: Completing the full sequence from 1 to 20 gives children a real sense of achievement.
Mastering the missing numbers 1-20 is a foundational skill. Once they feel happy with these, they will be much better prepared for more advanced tasks, like those found in Year 2 Maths Worksheets.
Tips for using this at home or in class
You don’t need any fancy equipment to make the most of this worksheet. Here are a couple of simple ideas:
- Use a Number Line: If your child gets stuck on the "teen" numbers (like 13 or 15, which can be confusing!), have a number line nearby. They can use it to "check" their answer before they write it down.
- Make it Reusable: If you want to use the sheet more than once, try popping it inside a plastic polypocket or laminating it. Your child can then use a dry-wipe marker to fill in the gaps, rub it out, and try again the next day.
This activity fits naturally with the UK National Curriculum goals for Year 1, specifically helping children to count, read, and write numbers to 100, starting with this vital 1-20 range.
We hope you and your little ones enjoy working through these numbers together!
