The Best Free Maths Websites And Apps For Teachers (Primary And Secondary)

Despite the increased used of AI by teachers to create their own resources (up from 31% to 58% by end 2025), free maths websites and apps are often an easier and more reliable way to find the resource you want when you want it. The hard part can be knowing which ones are worth your students’ time and which you open once and never reopen.

We have trawled the maths websites and tools that primary and secondary maths teachers actually rate, both for the classroom and for maths learning more widely, and grouped them by the job you are trying to do, from times tables games to challenging your high achievers. Every entry says which key stage and age group it suits, and we have flagged the ones that work well to set as homework or send home.

Key takeaways

• For primary maths resources, every time we survey teachers, they recommend Third Space Learning: for primary schools it’s the maths hub; and for secondary schools we have the secondary maths resources as well as the GCSE maths hub.
• For fluency, Times Tables Rock Stars and Topmarks’ Hit the Button lead; for problem solving, NRICH; for GCSE revision, Corbettmaths, Maths Genie (now YesGenie) and Physics & Maths Tutor.
• A couple of old favourites always make the list: Dr Frost has moved to drfrost.org and changed its access model for schools, and Hegarty Maths folded into Sparx some time ago.
• Other tools worth a look include Oak National Academy, Eedi, Polypad, Desmos and GeoGebra.
• Several work brilliantly to set as free maths homework or recommend for home, so we have included a ready-made paragraph you can drop into your school newsletter.

At a glance: which maths website for which job

How we chose these maths websites and apps

We judged each tool on four things:

• whether it is free or has a substantial free tier
• how well it supports the national curriculum
• what it is genuinely best for in the classroom
• the key stage and age group it suits

We rated them on usefulness rather than ranking one to ten, because the best site for setting times tables homework is not the best site for an end-of-topic reasoning challenge. Every tool here was created by teachers or subject specialists with deep subject knowledge, and we have said where a once-free tool has moved behind a paywall.

What are the best free maths websites and resources

Maths for planning and worksheets

Start here for ready-made planning, worksheets and schemes of learning.

Third Space Learning maths hub – KS1 to KS2 (primary)

This one is ours, so rather than mark our own homework, here is a primary deputy head on the impact of our resources: “Our children were well prepared for SATs this year having done daily Fluent in 5.” (Karen Price, Deputy headteacher, Brompton-Westbrook Primary School.) Fluent in Five is one of our daily arithmetic resources.

The maths hub and wider free maths resources library are created by qualified UK teachers and maths specialists, mapped to the curriculum and much of it aligned to White Rose. You will find lesson slides, SATs papers, and a daily KS2 maths challenge that works as a lesson starter. The primary maths resources collection is the quickest way in.

Website: https://mathshub.thirdspacelearning.com/

White Rose Education – KS1 to KS4 (strongest in primary)

The de facto national primary scheme with many providers offering White Rose Maths resources. The schemes of learning and small-step guidance are easy to lift into planning, even if your school does not formally follow White Rose. Many worksheets cost nothing; some premium material is paid.

Website: https://whiteroseeducation.com/

Oak National Academy – KS1 to KS4

Government-funded and free, Oak offers a full sequenced curriculum of slide decks, quizzes and teaching videos (the mathematics developed with MEI and endorsed by NCETM), all adaptable for your class. The closest thing to a whole-curriculum-in-a-box. Now also with Aila, their AI assistant for creating your own personalised resources.

Website: https://www.thenational.academy/

NCETM – KS1 to KS4

The authority on mastery pedagogy and an excellent source of subject knowledge for teaching mathematics. Best for departmental CPD and planning, and it supports schools with ready-to-progress criteria, representation and bar-model guidance, and the Maths Hubs network. It also tracks how the new curriculum and the latest research are shaping classroom practice.

Website: https://www.ncetm.org.uk/

Primary Resources – KS1 to KS2

A long-standing bank of printable worksheets and exercises sorted by topic and ability. The design is dated, but for quick primary resources to use in class it is still an old faithful, and you can download everything.

Website: https://www.primaryresources.co.uk/maths/maths.htm

Go Teach Maths – KS3 to KS4

A secondary staple. Hundreds of handcrafted, classroom-ready lessons, with strong practical games, cooperative tasks and exercises. Most unfortunately are paid but they have some good mark maximisers for GCSE.

Website: https://www.goteachmaths.co.uk/

Which free maths apps are best for fluency and times tables?

These are the tools for daily number facts and times tables work.

Times Tables Rock Stars – KS2 (some KS3)

Still the best of the games for times tables motivation, and strong preparation for the Year 4 multiplication tables check. It is now a paid school subscription with a free trial, but teachers rate it worth the money. Good to set as homework, as students happily keep playing on their own devices, and one of the best ways to get a whole class of pupils fluent in their tables.

Website: https://ttrockstars.com/

Hit the Button, by Topmarks – KS1 to KS2 (ages 5 to 11)

Instant, no login, and one of the best-loved online maths games for number facts: number bonds, times tables, doubling and halving and division facts, with a timed mode that mirrors the multiplication check. Great to set for homework, and a quick way to help children become fluent in number facts from bridging ten to subitising. Use the official site at topmarks.co.uk, as several copycat domains exist.

Website: https://www.topmarks.co.uk/maths-games/hit-the-button

Mathsframe – KS1 to KS2

Over 200 curriculum-mapped online maths games covering every KS1 and KS2 objective. The free tier needs no login; a low-cost option adds pupil tracking, and the games make reliable, fun mental maths starters that children enjoy.

Website: https://mathsframe.co.uk/

What are the best for problem solving and reasoning

When you want to stretch thinking rather than drill a method, reach for these.

NRICH – KS1 to KS5 (all ages and abilities)

The gold standard for rich, low-threshold-high-ceiling tasks that challenge children of any ability. It encourages children to think like mathematicians, suits a wide range of abilities, and the teacher notes are thorough. From the University of Cambridge, with university-level thinking made accessible to school children.

Website: https://nrich.maths.org/

Transum – KS2 to KS5

A “Starter of the Day” for every day of the year, plus a large bank of self-marking activities, maths games and tasks. Excellent for bell-work, end-of-lesson challenge and problem solving across a wide age range.

Website: https://www.transum.org/

Eedi (Diagnostic Questions) – KS2 to KS4 (ages 9 to 16)

Diagnostic quizzes where each wrong answer pinpoints a misconception, built by Craig Barton’s team. It has been through an EEF research trial, and it helps children feel more confident by closing knowledge gaps before they widen.

Website: https://eedi.com/

What are the best free GCSE maths revision websites?

For KS3 to GCSE revision, these are the sites your students should know.

Third Space Learning secondary maths resources – KS3 to GCSE

Ours again, so here is a teacher’s view rather than ours: “The best thing about the secondary resources is that they’re separated into exam boards, and that they give answers. They save a lot of time.” (Kate Davies, Maths Director, Outwood Grange Academies Trust.) The secondary maths resources section has GCSE worksheets, past papers and revision guides, organised by exam board with answers included.

Website: https://thirdspacelearning.com/secondary-resources/

Corbettmaths – KS2 to GCSE and Further

More GCSE revision although the quality can vary: 5-a-day daily questions at every tier, videos, worksheets with answers and exam papers. A separate primary 5-a-day site runs too. Works well as homework you can set and forget, and as a site to send home for children to revise.

Website: https://corbettmaths.com/

Maths Genie, now YesGenie – GCSE and A level

Revision arranged by grade, tier and topic, with past papers and a new paper-builder. Walkthrough videos cover most topics, helping students feel confident going into exams. Still free under its new name.

Website: https://yesgenie.com/

Physics & Maths Tutor – GCSE, IGCSE and A level

A huge bank of past papers and questions-by-topic with mark schemes, videos and model solutions, no login. The honest alternative to paywalled revision sites, and especially strong for students heading to university to study mathematics.

Website: https://www.physicsandmathstutor.com/

Dr Frost Maths – upper KS2 to A level

Now at drfrost.org, with auto-marking worksheets, tens of thousands of real exam questions and worked-example videos. Free for students; schools get full access via a trial (check current pricing).

Website: https://www.drfrost.org/

Explainers and video for all ages

When a pupil or family needs a concept explained clearly, point them to these online explainers.

BBC Bitesize – KS1 to KS3 and GCSE

The trusted educational reference, organised by year group and curriculum, with short videos that make tricky methods accessible. A good site to set as homework so children can catch up, and strong for building confidence with an unfamiliar method.

Website: https://www.bbc.co.uk/bitesize

Khan Academy – KS2 to A level

Videos, games and mastery practice, good for self-paced learning and catch-up at home. The structure follows US grades, so it suits concept-building more than English exam preparation, and the videos help children learn at their own pace.

Website: https://www.khanacademy.org/

Math is Fun – KS1 to KS4

Do not be put off by the US spelling. Clear, plain-language explanations, games and worked examples, plus a useful illustrated maths dictionary. A handy educational reference for students.

Website: https://www.mathsisfun.com/

Interactive tools and virtual manipulatives

For modelling maths visually, these three tools lead.

Polypad, Desmos and GeoGebra – KS1 to A level

Three classroom-grade online tools: Polypad (now part of Amplify), the best virtual manipulatives library from fraction bars to algebra tiles; Desmos, the standard graphing calculator with interactive tasks and games; and GeoGebra, which adds dynamic geometry and 3D with a live student view. All three suit a wide range of ages and abilities, from primary play to university.

Setting these for homework and sharing them with parents

Teachers are often asked by families how can I help my child with maths homework at home? Rather than answer it twenty times, set the right site as homework and drop a short recommendation into your school newsletter or a parents’ email. Here is a paragraph you are welcome to copy and adapt:

Looking for free maths homework help at home? A few websites we rate: Third Space Learning has high quality resources, many of which are free, BBC Bitesize explains every topic by year group, Hit the Button builds times tables and number bonds through quick games children genuinely enjoy, and the White Rose 1-Minute Maths app is perfect for a daily five-minute burst. Little and often works best, and the aim is to build your child’s confidence rather than to turn the kitchen table into a classroom.

Pointing families to one or two trusted sites, rather than a long list, keeps it manageable. The tools tagged “good to send home” above need the least explanation for children to get started, and several let children compete with other students, which encourages children to keep coming back week after week. Set as homework, they double as free homework help that costs families nothing.

A maths lead’s tip: a website of the month

One maths lead we work with runs a “maths website of the month” in the newsletter: one site, one line on what it is for, and one idea for how parents and children can use it for ten minutes a week. Rotating through the tools above keeps it fresh, helps build a homework routine, and grows children’s confidence without overwhelming anyone with a long list. It is a small, fun habit that quietly does a lot of the home learning for you.

When you need the teaching done, not just the resources

These websites and tools are great for homework and revision, but they cannot sit beside a child and work through a misconception. That is where one-to-one teaching still matters, and where it has traditionally been too expensive to offer at scale.

Skye, our voice-based AI maths tutor, is built by teachers and maths specialists to give students personalised, one-to-one lessons that find and close gaps through spoken dialogue, giving hints rather than answers. It uses the same pedagogy, curriculum and lesson structure as our traditional one-to-one tuition, but with the flexibility to support every child who needs it, at a low fixed cost. Sessions run before, during and after school, either booked to fit your timetable or scheduled on demand at school or at home.

Since 2013 we have delivered more than 2,295,000 hours of online maths tuition to over 196,000 students across 4,200 schools. If these tools are not enough on their own, you can see how the AI maths tutor works.

Frequently asked questions

What is the best free maths website for primary teachers?

It depends on the job. For planning and worksheets, Third Space Learning’s maths hub and White Rose Education are strong, with Primary Resources a handy back-up. For fluency, Times Tables Rock Stars and Hit the Button lead. For problem solving and challenging high achievers, NRICH. Most primary teachers use a combination across key stages.

Can children use these maths websites at home for homework?

Yes. Tools like BBC Bitesize, Corbettmaths, Hit the Button and the White Rose 1-Minute Maths app work well to set as homework and for free maths homework help, because they need little setup and align to the curriculum. They are a simple way for families to support children’s maths learning at home and build confidence.

What free maths resources are best for secondary and GCSE?

Third Space Learning’s secondary maths resources, Corbettmaths, Maths Genie (now YesGenie) and Physics & Maths Tutor are the staples, covering worksheets, graded questions, past papers, videos and model solutions across KS3 and KS4.

Are these maths websites and apps completely free?

Most cost nothing or offer a substantial free tier. A few have changed: Times Tables Rock Stars is a paid school subscription with a trial, and Dr Frost has changed its access model. Always check current terms.

How do I choose between all these maths websites?

Start from the job: fluency, planning, problem solving or revision. Pick one strong tool per job and per age group rather than spreading across many. One of the best ways to keep it manageable is to master a small set well.
