KS1 Maths Worksheets (Free Printable)
What KS1 Covers
Key Stage 1 runs through Years 1 and 2 (ages 5 to 7) and lays the foundation for every maths skill that follows. The focus is on number sense, the four operations with small numbers, place value, measurement, and simple geometry.
KS1 maths isn't about speed or memorisation. It's about building concrete understanding of numbers using real objects, pictures, and simple problems. Worksheets can absolutely play a role — but they work best alongside hands-on activities, not instead of them.

The KS1 Curriculum
Here is what KS1 pupils should learn over Years 1 and 2:
- Number and place value — counting forwards and backwards, reading and writing numbers to 100 (Y1) and 1,000 (Y2)
- Addition and subtraction — within 20 (Y1), within 100 with written methods (Y2)
- Multiplication and division — 2, 5 and 10 times tables, basic division
- Fractions — halves and quarters in Y1, thirds added in Y2
- Measurement — length, mass, capacity, time, money
- Geometry — 2D and 3D shapes, position and direction
- Statistics — simple pictograms and tally charts (Y2 only)
Year 1 (Reception / US Kindergarten)
Year 1 pupils are ages 5 to 6 and starting their first full year of formal schooling. Maths at this age is highly concrete — using counters, fingers, pictures, and real-world objects.
Key Year 1 skills:
- Counting to 100
- Reading and writing numbers to 20
- Number bonds to 10
- Adding and subtracting within 20 (sometimes with pictures)
- Recognising halves and quarters of shapes and amounts
- Telling time to the hour and half past

Year 2 (Year 1 in US / UK Year 2)
Year 2 pupils are ages 6 to 7 and starting to move from concrete materials to simple written methods. The 2, 5 and 10 times tables are introduced, and pupils begin adding and subtracting 2-digit numbers.
Key Year 2 skills:
- Counting to 100 and beyond
- Adding and subtracting within 100 using written methods
- 2, 5 and 10 times tables (forwards and backwards)
- Fractions — halves, quarters, thirds
- Money — combinations of coins up to a pound
- Telling time to the nearest 5 minutes

Keep Sessions Short
KS1 pupils have short attention spans — 10 minutes is about right for focused practice. Longer sessions lead to tired, frustrated children who start guessing rather than thinking.
A typical KS1 maths session looks like:
- 2 minutes: warm-up (counting, number bonds, or a game)
- 7 minutes: focused practice on one topic
- 1 minute: end on a win with an easy problem
That's enough to make real progress without burning anyone out.
Make It Playful
At this age, maths should feel like play. Use real objects wherever possible — buttons for counting, cups for measuring, biscuits for sharing and dividing. Turn worksheets into games with timers and stickers.
Avoid timed tests at this age. Speed is the wrong goal. Understanding is the goal, and speed comes naturally once understanding is solid.
Supporting Your Child
A few tips for KS1 maths at home:
- Sit with your child while they work. This isn't independent study yet.
- Talk about what you're doing aloud. "I have 3 buttons. If I add 2 more, how many?"
- Celebrate effort, not speed. "You tried a hard one — well done!"
- If your child is stuck, back up. The right level feels challenging but doable.
Free and Printable
All our KS1 worksheets are free to download, printable on any home printer, and come with answer keys. Pick the topic your child is learning this week and print what you need.
Regular practice in short, focused sessions is the best way to build strong KS1 foundations. Those foundations are what make Years 3 to 6 so much easier.
