Best homeschool resources for KS3

Key Stage 3 (KS3) is the middle years – ages 11 to 14, roughly Years 7, 8 and 9. For a homeschool family it is a valuable phase because there is no exam pressure, no fixed specification to follow, and the pace is entirely yours to set. The point of KS3 is to consolidate the basics, broaden the child's knowledge across subjects, and build the study habits that make Key Stage 4 (KS4) and GCSE feel manageable when you get there.

The risk with KS3 is that families either over-schedule (recreating a school day at home) or under-schedule (drifting through three years without a clear scope). The right shape sits somewhere in the middle: a light structure covering the core subjects, a rotation of humanities and sciences across the week, and space for a couple of things the child is interested in.

This roundup covers what works in practice for homeschool KS3 in 2026, grouped by subject and split by free versus paid.

Legally, there is no requirement to follow the National Curriculum when home educating. Department for Education guidance is explicit on this. In practice, most homeschool families cover roughly what a state school covers at KS3, because it makes the transition into GCSE work easier and because the National Curriculum is a reasonable scope even if it is not compulsory.

A workable KS3 scope: English (reading widely, writing regularly, some grammar), Maths (arithmetic fluency plus algebra, geometry and stats), Sciences (Biology, Chemistry and Physics as separate strands), Humanities (History, Geography, Religious Studies), a modern foreign language, computing basics, art or music, and PE. Not every subject needs equal weight. English and Maths sit at the core. Sciences and Humanities rotate. The rest is where you have room to follow interests.

The reason to keep breadth in KS3 is that GCSE subject choices in Year 9 or Year 10 are much easier when the child has met each subject at a meaningful level. A student who has done no Geography since Year 6 cannot really pick between Geography and History at GCSE.

KS3 English breaks down into three things: reading widely, writing regularly, and building the grammar and vocabulary that GCSE English Language will assume.

Reading is where the library beats any platform. A KS3 child reading independently for 20–30 minutes a day, across a wide range of fiction and non-fiction, is doing more than most schools manage. Support that with a rotating list of set texts – aim for one novel every four to six weeks and a poetry anthology alongside.

BBC Bitesize KS3 English is a solid free structured resource for grammar, writing techniques and set-text summaries. The topic pages are short and readable, which is exactly what you want at this stage.

Oak National Academy publishes free KS3 English lesson sequences covering the main writing forms, grammar, and set texts. It is heavier than Bitesize and works well as a scheme of work if you would rather follow a structure than build one.

Cognito's KS3 English notes are useful for grammar practice and short writing tasks. Notes are free; the topic-tagged question bank and flashcards are free with a weekly limit and unlimited on Cognito Pro.

KS3 maths is where consistency matters most. A child who does 20–30 minutes of maths a day, six days a week, will be far better prepared for GCSE than one who does long sessions twice a week.

Corbett Maths is a popular free KS3 maths platform. Short video worked examples, printable practice sheets and the 5-a-day questions – which are exactly the kind of low-friction daily practice that KS3 needs.

Dr Frost Maths is a free interactive platform covering KS3 through A-Level. Students work through topic-tagged questions with immediate feedback and the platform tracks progress. Strong for students who like a gamified, structured feel.

Cognito publishes free KS3 Maths video lessons and notes, with a topic-tagged question bank free with a weekly limit (unlimited on Cognito Pro). Works well alongside Corbett Maths – Cognito for teaching, Corbett for practice sheets.

Khan Academy is US-based but the maths content maps well onto UK KS3. Useful for a student who needs a topic re-explained a different way.

CGP KS3 Maths workbooks are cheap and effective. A single workbook per year covers most of the KS3 scope and the practice questions are well-graded.

KS3 science covers Biology, Chemistry and Physics as separate strands. The point is to build a mental model of each subject, meet the key vocabulary, and do some practical work – not to cover every topic at depth.

Cognito publishes free KS3 Science video lessons and notes across Biology, Chemistry and Physics, alongside a topic-tagged question bank (free with a weekly limit, unlimited on Cognito Pro). The lessons are short and examiner-focused – overkill for KS3 in some ways, but a good spine that means the same resource can carry the student into GCSE.

BBC Bitesize KS3 Science covers the same three strands with short topic pages. Useful for a quick introduction to a topic.

Oak National Academy publishes free full KS3 Science lesson sequences. Good if you want a schemes-of-work-style structure.

For practical work, the Royal Society of Chemistry, Institute of Physics and Royal Society of Biology all publish free home-friendly experiment ideas that use kitchen equipment. Small practicals – growing bean plants, testing food for starch, making a simple circuit – matter more than expensive lab kits at KS3.

Humanities at KS3 (History, Geography, Religious Studies) work well on a rotation model. Two subjects a term, changing every half term, rather than trying to run all three every week.

BBC Bitesize KS3 covers all three subjects with structured topic pages. Solid free spine.

Oak National Academy has full KS3 History and Geography lesson sequences. Heavier and more structured than Bitesize.

The National Archives Education Service (nationalarchives.gov.uk/education) publishes free primary-source history resources, organised by KS3 topic. Excellent for building source-analysis skills that GCSE History will draw on.

Cognito's KS3 coverage includes History, Geography and Religious Studies notes and questions – useful if any of the three is on the rotation.

For Geography, the RGS-IBG (Royal Geographical Society with the Institute of British Geographers) publishes free KS3 lesson materials at rgs.org.

Modern foreign languages at KS3 are best served by a mix of vocabulary practice, video content and short conversational practice.

Duolingo (free with ads, or a paid Super Duolingo tier, roughly £6–£7/month on the annual plan) is a reliable everyday option. Not enough on its own, but a consistent 10-minute daily habit builds vocabulary and grammar recognition.

Memrise (free and paid tiers) works alongside Duolingo, especially for listening practice using native speakers.

BBC Bitesize KS3 covers French, Spanish and German with structured topic content.

Quizlet is useful for building topic-specific vocabulary sets aligned to whatever grammar strand you are working on that week.

Cognito covers French, Spanish and German with notes, questions and flashcards at KS3 and GCSE, which is useful for structured vocab and grammar practice alongside a conversational tool.

Italki or Preply for occasional short (30-minute) conversation lessons with a native speaker at around £10–£20 per session works well from about Year 8 onwards – conversation is the skill hardest to build without a human on the other end.

If a DIY stack is not the right shape for your family, several UK online schools accept KS3 students.

King's InterHigh runs live-lesson KS3 provision (Middle School, Years 7–9) as part of its full ages-7-to-18 school. Received DfE Online Education Accreditation in February 2026. Fees are published as a range roughly £2,750–£6,605 per year – verify current pricing directly with the school for the KS3 stage.

Wolsey Hall Oxford runs a self-paced KS3 Lower Secondary programme with UK-qualified tutor feedback. Bundle-priced by number of courses (1–3 / 4 / 5+ subjects) with a £95 one-off registration. Verify the current fee schedule on Wolsey Hall's site.

Cambridge Home School Online runs KS3 (Lower School) at £10,950 per year – small-class live lessons mirroring an independent day school.

Oxford Home Schooling sells KS3 courses at a lower price point per subject than GCSE – confirm current fees directly.

Cognito's KS3 coverage runs across the three sciences (Biology, Chemistry, Physics), Maths, English, Geography, History, Religious Studies and modern foreign languages, with more subjects being added over time. Videos and notes are free across all covered subjects; the question bank, flashcards and quiz builder are free with a weekly limit and unlimited on Cognito Pro.

The advantage of using Cognito at KS3 is continuity: the same platform carries into GCSE, A-Level and IB. A student who starts using Cognito in Year 7 will still be using it in Year 11 (and beyond), and the topic map builds progressively across the years. That is easier than switching platforms mid-KS4.

At this stage, use Cognito as one of two or three tools rather than the only one – short video lessons and topic-tagged practice sit alongside library reading, workbooks and the humanities resources above.
