These free before and after numbers worksheets give you five number sense printables: before and after numbers to 20 and to 100, numbers in between, missing numbers to 100 and hundreds chart puzzles, each with an answer page, on US Letter and A4, in colour and in black and white. I’m Patrick Elliott, a teacher and Inclusion Lead. I chose the numbers so that every worksheet mixes easy and tricky cases, such as the number after 29 or before 70, and built an answer page for every sheet from the same numbers, so the key always matches.
In this guide, you’ll find which worksheet suits which stage, how to teach before, after and between with a number line, and how to use the hundreds chart puzzles.
What’s in the Before and After Numbers Worksheets
| Worksheet | What is on it |
|---|---|
| Before and After Numbers to 100 | 18 numbers to 100, with an answer page |
| Before and After Numbers to 20 | 18 numbers to 20, with an answer page |
| Missing Numbers to 100 | A hundreds chart with 45 numbers to fill in, with an answer page |
| Hundreds Chart Puzzles | Six pieces cut from a hundreds chart: fill in the missing numbers, with an answer page |
| Numbers in Between | 18 pairs to 100, with an answer page |
👉 Every number sits in a Word table cell, so you can type new numbers before you print. The answer page on page 2 shows every missing number in bold.
What Do Before and After Numbers Worksheets Practise?
The number just before is one less, and the number just after is one more. Children who can answer “what comes before 43?” straight away understand how the counting sequence works, not just how to recite it. That is the foundation for counting on, adding and subtracting 1 and 10, and reading a hundreds chart. These worksheets start with numbers to 20, move to numbers to 100, then ask for the number in between and the missing numbers on a whole hundreds chart.
Which Before and After Numbers Worksheet Should You Use?
- Before and After Numbers to 20: 18 numbers to 20, with a Before and an After box for each.
- Before and After Numbers to 100: 18 numbers to 100 in the same layout.
- Numbers in Between: 18 pairs to 100, such as 60 and 62, with the number in between to write.
- Missing Numbers to 100: a missing numbers worksheet 1-100: a hundreds chart with 45 numbers to fill in.
- Hundreds Chart Puzzles: six pieces cut from a hundreds chart, each with one or two numbers given. Children fill in the rest, using one more and one less across, and ten more and ten less up and down.
- Answer pages: every worksheet has its answers on page 2.
How to Use the Before and After Numbers Worksheets
- Choose your paper size above, download the ZIP and print page 1 of the worksheets you need.
- Start with the worksheet to 20 and show before and after on a number line: one step back, one step forward.
- Move to numbers to 100 once children can answer to 20 without counting from 1.
- Use numbers in between and the missing numbers worksheet to bring the three ideas together.
- Finish with the hundreds chart puzzles, then check every sheet with its answer page.
Keep a 100 chart or a number line nearby for children who need to check, and take it away once they are confident. Ready for the next step? Try the skip counting worksheets and the place value worksheets.
Black and White Versions
Every before and after numbers worksheet also comes in black and white, with the same tables and black headings, so it prints clearly and saves ink. In the download box, choose Colour, Black and white or All, then your paper size: A4, US Letter or both.
How to Print the Before and After Numbers Worksheets
Print at 100% (Actual size) on the same paper as the file, US Letter or A4. Each file has the worksheet on page 1 and the answers on page 2, so print page 1 only for the class.
