KS1 vs KS2 – What Should My Child Know? A Parent's Guide to Key Stage Learning

If you're a parent navigating the UK school system, the terms KS1 and KS2 can feel a little confusing at first. What exactly should your child know by the end of each Key Stage — and how can you support them at home? Here's everything you need to know.

What Is KS1?

Key Stage 1 covers Years 1 and 2, for children aged 5 to 7. It's the foundation stage of primary school, where children begin to build core literacy and numeracy skills.

By the end of KS1, your child should be able to:

  • Read simple texts with confidence and understanding
  • Write sentences using capital letters, full stops, and basic punctuation
  • Spell common words correctly (the Year 2 spelling list is a good guide)
  • Add and subtract numbers up to 100
  • Understand basic multiplication and division concepts
  • Recognise and name 2D and 3D shapes
  • Tell the time to the nearest 15 minutes

The KS1 SATs (taken in Year 2) assess reading, maths, and grammar — though results are used by teachers rather than being high-stakes for children.

What Is KS2?

Key Stage 2 covers Years 3 to 6, for children aged 7 to 11. This is where learning becomes more structured and the curriculum broadens significantly.

By the end of KS2, your child should be able to:

  • Read fluently and discuss texts in depth
  • Write in a range of styles — stories, reports, persuasive writing
  • Use grammar, punctuation, and spelling accurately (including the Year 6 spelling list)
  • Work confidently with fractions, decimals, and percentages
  • Multiply and divide multi-digit numbers
  • Understand basic algebra and geometry
  • Recall all times tables up to 12×12

The KS2 SATs in Year 6 are more formal and results are used for secondary school transitions.

How to Support Your Child at Home

You don't need to be a teacher to make a real difference. Little and often is the key — even 15–20 minutes of practice a day adds up quickly.

Some simple ways to help:

  • Read together every day, even if it's just a few pages
  • Practise times tables in the car or at mealtimes
  • Use printable worksheets to reinforce what they're learning in class
  • Make it fun — games, puzzles, and colouring activities all count!
