Years 7–9 · Key Stage 3 · Three-year route · Aligned to the National Curriculum for England

This free 3-year Key Stage 3 maths scheme of work is a complete medium-term plan for Years 7, 8 and 9. It is written for Heads of Mathematics and classroom teachers who want a coherent KS3 backbone that secures core number, algebra, geometry, ratio & proportion, statistics and probability — and prepares every student well for GCSE in Year 10.

Every topic links to a dedicated teaching page. Members get the full teaching package — interactive lesson, printable worksheet, retrieval practice and worked solutions — so departments can reduce planning time while keeping consistent coverage across all KS3 classes.

Who is this scheme for?

The 3-Year Key Stage 3 scheme of work is built for UK mainstream secondary maths departments that teach KS3 across Years 7, 8 and 9 before starting GCSE in Year 10. It also fits international British-curriculum schools that follow the National Curriculum for England.

• Heads of Mathematics writing or refreshing a KS3 medium-term plan and wanting one consistent route every teacher can follow.
• Classroom teachers who need ready-made lessons, worksheets and retrieval tasks for every KS3 topic, without rebuilding resources from scratch.
• Early career and trainee teachers looking for clear topic sequences, well-modelled examples and worked solutions to support confident first delivery.
• Tutors, home educators and SENCOs who want a structured KS3 route with stretch on key concepts (e.g. fractions, ratio, algebraic notation) and gentle bridges into GCSE in Year 9.
• Mixed-attainment and setted classes — the sequence works in both, with optional extension topics in Year 9 (trigonometry, simultaneous equations) for confident groups.

What’s included

A complete medium-term plan for three years of Key Stage 3 mathematics (Years 7–9), with every topic linked through to teaching resources:

• Year-by-year, term-by-term sequence across Years 7, 8 and 9 (6 half-terms × 3 years).
• Strand-balanced coverage across Number, Algebra, Geometry, Statistics and Ratio & Proportion.
• Direct links to every topic page with teaching overview, prerequisites, key concepts and common misconceptions.
• Member access to the full interactive lesson, printable worksheet, retrieval practice and worked solutions for every topic.
• Bridges into GCSE — Year 9 deliberately revisits and deepens percentages, transformations, graphs and Pythagoras so the move into Year 10 is smooth.
• Free 5-Year Curriculum PDF showing the 3-Year KS3 + 2-Year GCSE model end-to-end — useful for whole-school curriculum mapping.

How to use this scheme

Each year is divided into six half-terms (Autumn 1 through Summer 2) with topics in the order shown. Allow roughly 2–3 weeks per topic depending on your timetable, set structure and starting points. The sequence is a backbone, not a straitjacket — reorder, combine or extend topics to match your classes.

Most departments embed retrieval practice at the start of every lesson, low-stakes quizzes mid-topic, and short cumulative reviews between topics. The KS3 sequence deliberately revisits core ideas across the three years (percentages, graphs, geometric reasoning, fractions) so students meet familiar ideas in new contexts and build secure long-term recall.

Pair the topic pages with Mr Mathematics retrieval starter tasks for Years 7, 8 and 9 to make daily recall easy to run.

Curriculum rationale

The 3-Year KS3 route gives students time to secure foundational number and shape work before progressing to abstract algebraic structure and proportional reasoning. Year 7 prioritises place value, the four operations, properties of shape and early algebraic notation. Year 8 broadens to indices, multiplicative reasoning, statistical interpretation and geometry. Year 9 prepares the ground for GCSE with percentages, transformations, formulae, Pythagoras and proportional reasoning.

• Year 7 — secures place value, properties of shape and the four operations; introduces algebraic notation, basic geometric reasoning and early data work.
• Year 8 — develops indices, accuracy, polygons, fractions and ratio; consolidates algebraic manipulation and constructions.
• Year 9 — deepens percentages, transformations and graphs; introduces Pythagoras, compound measures, proportional reasoning and (optionally) trigonometry and simultaneous equations to bridge into GCSE.

Students completing this scheme should be well prepared for either the GCSE Foundation or GCSE Higher three-year route in Years 10–12. Departments that need a condensed two-year KS3 model should instead use the 2-Year Key Stage 3 scheme of work.

Frequently asked questions

Is this scheme aligned to the National Curriculum for England?

Yes. The 3-Year Key Stage 3 scheme of work is mapped to the National Curriculum programme of study for KS3 mathematics, covering Number, Algebra, Ratio & Proportion, Geometry & Measures, Probability and Statistics. Year 9 also begins to bridge into the 9–1 GCSE specifications used by Edexcel, AQA, OCR and WJEC, so the move into Year 10 GCSE is smooth.

How long should we spend on each topic?

Most KS3 topics in this scheme run for 2–3 weeks (typically 6–9 lessons) depending on your timetable, set structure and the starting points of the class. Each half-term is sized to fit comfortably into a UK school term, with built-in time for retrieval practice, assessment and review. Heads of Maths typically allocate slightly longer to core ideas such as fractions, ratio and algebraic manipulation, and shorter time to consolidation topics that revisit Year 7 content in a new context.

Can we reorder the topics to fit our department’s plan?

Yes — the scheme is designed as a backbone, not a straitjacket. The order has been carefully sequenced so prerequisites are met (for example, place value before decimals, fractions before ratio, properties of shape before angle properties), but you can move topics within a year or swap half-terms to match your timetable, shared resources or feeder primary input. The free PDF makes it easy to print the full sequence and re-mark it for your school.

What’s included for free, and what needs membership?

The scheme of work itself — including every topic link, the curriculum rationale and the 5-Year Curriculum PDF — is free for all teachers to view, download and use in school planning. Each topic page is also free to read for its teaching overview, prerequisites, key concepts and common misconceptions. Mr Mathematics membership unlocks the full classroom package for each topic: interactive lesson presentations, printable worksheets, retrieval practice and detailed worked solutions.

How does this 3-Year KS3 scheme link to GCSE?

Year 9 deliberately revisits and deepens high-leverage GCSE topics — percentages, transformations, equations of straight line graphs, formulae, Pythagoras’ theorem, compound measures and proportional reasoning — so students enter Year 10 already familiar with the language and methods. Departments running this scheme typically continue into the 3-Year GCSE Foundation or GCSE Higher routes in Years 10 and 11.

Do you have retrieval starter tasks to use alongside the scheme?

Yes. The Mr Mathematics retrieval starter tasks provide sequenced 5–10 minute starters for Year 7, 8 and 9 that interleave prior learning with current-topic content. Members can download sets 2 onwards directly; Set 1 for each year is free for all teachers.
