"Key Stage 1" is one of those school terms that gets used constantly and explained rarely. If your child is heading into it — or you're covering it at home — here's what it actually means.
The short version
Key Stage 1 (KS1) covers school Years 1 and 2 in England, roughly ages five to seven. It's the stage that follows EYFS, and it's where learning starts to look a little more structured — proper reading books, written maths, and the beginnings of subjects like science and history.
What's actually covered
- English — phonics moving into fluent reading, simple sentence writing, spelling and punctuation basics
- Maths — numbers to 100, addition and subtraction, an introduction to multiplication and division, shapes and measuring
- Science — everyday materials, plants, animals, and the human body, mostly through observation and simple experiments
- Wider learning — art, music, PE, and early geography/history, usually topic-based
Does it matter if you're home educating?
Not in the sense that you have to follow it exactly — home educators in England aren't legally required to follow the National Curriculum. But KS1 is still a useful map. It tells you roughly what other five-to-seven-year-olds are covering, which is handy for pacing yourself, and it's exactly the range LearnLeaf's worksheets are built around.
Where to start
If you want a practical starting point rather than a syllabus, our Numbers for Kids and Reading, Writing & Literacy categories map closely to the two subjects that get the most focus at KS1, and both are free to browse and print.
