Finding the right free maths resources online can feel overwhelming. There are hundreds of websites claiming to help your child, but not all of them are curriculum-aligned, easy to use, or actually engaging for children. This guide reviews the best free maths websites for primary school in the UK, focusing on KS1 (Years 1–2) and KS2 (Years 3–6).
What to Look for in a Free Maths Website
Before diving into the list, here’s what separates good resources from generic ones:
- UK National Curriculum alignment — topics should match what’s taught in English schools, not the American or Australian curriculum.
- Year group specificity — broad “primary maths” content is less useful than resources organised by Year 1, Year 2 etc.
- Interactivity — worksheets have their place, but interactive activities keep children more engaged and give instant feedback.
- No paywall on core content — truly free means no credit card required to access the main resources.
The Best Free UK Primary Maths Websites
1. Skoolmaths
Skoolmaths offers curriculum-aligned interactive maths lessons and activities for every year group from Preschool to GCSE. The free resources section includes worksheets and activities with no sign-up required, and the year group pages are organised exactly as the UK National Curriculum expects — making it easy to find exactly what your child is learning in class.
Best for: Parents and teachers who want UK-specific, year-group-accurate resources with an interactive element.

2. BBC Bitesize
BBC Bitesize remains one of the most trusted free educational resources in the UK. Its primary maths section covers KS1 and KS2 with videos, games and quizzes. The content is clearly labelled by key stage and subject, though it is less granular by year group than dedicated platforms.
Best for: Quick video explanations and games to supplement classroom learning.
3. Times Tables Rock Stars (free version)
TTRS offers a limited free version with multiplication practice. Many schools use it, making it familiar to children. The focus is narrow — times tables only — but it’s excellent for that specific skill.
Best for: Year 4 times tables practice ahead of the Multiplication Tables Check.
4. Topmarks
Topmarks is a directory of free educational games and activities, including many maths games for primary age children. The quality varies across different games, but there are strong options for number bonds, multiplication and mental arithmetic.
Best for: Short, game-based maths practice for younger children.
5. White Rose Maths (free resources)
White Rose Maths is used in many UK primary schools and offers free worksheets aligned to their popular schemes of learning. The resources are high quality but more worksheet-focused — less interactive than other options on this list.
Best for: Parents whose children’s schools follow the White Rose Maths scheme.

The honest answer is that different resources suit different children and different purposes:
- For interactive lessons by year group: Skoolmaths
- For quick video explanations: BBC Bitesize
- For times tables specifically: Times Tables Rock Stars
- For maths games: Topmarks
- For printable worksheets: White Rose Maths
