Stage 8 Cambridge Lower Secondary Maths (syllabus 0862) covers four strands: Number, Algebra, Geometry and Measure, and Statistics and Probability. The topics that create the most difficulty at Stage 8 are Standard Form (new in this stage), equations with brackets, angles in parallel lines, and probability trees. Practise these topic by topic before attempting full mixed papers.
Stage 8 is where gaps begin to appear for many Cambridge Lower Secondary students. Algebra shifts from substitution and simple equations at Stage 7 to expanding brackets, factorising, and solving equations with unknowns on both sides. Standard Form is introduced for the first time. In Statistics, tree diagrams appear — a concept that many students find unintuitive until they have seen several worked examples. A student who managed well in Stage 7 with general effort often needs more targeted revision in Stage 8.
The following sections cover every topic in the Stage 8 Cambridge Maths framework, how to approach practice sessions, and what resources target the specific Stage 8 gaps.
What Stage 8 Cambridge Maths Covers (Syllabus 0862)
Cambridge Lower Secondary Maths is organised into four strands across all stages. The Stage 8 content for each strand is listed below, drawn from the published Cambridge curriculum framework 0862.
Strand 1 — Number
- Integers: directed numbers, operations with negative numbers
- HCF and LCM: finding highest common factor and lowest common multiple using prime factorisation
- Standard Form: writing large and small numbers as a × 10n; converting between standard and ordinary form
- Percentage change: increase and decrease as a percentage of the original value
- Ratio and proportion: dividing quantities in a given ratio, working with direct proportion
- Reverse percentage: finding the original amount before a percentage change was applied
Standard Form is the topic that surprises most Stage 8 students — it is new, it uses notation they have not seen before, and it requires understanding of negative exponents. It is also reliably tested in Stage 8 assessments and in the Checkpoint exam. Getting comfortable with Standard Form early in Stage 8 pays dividends throughout the year.
Strand 2 — Algebra
- Expanding and factorising: single-bracket expansion; factorising by taking out a common factor
- Solving equations: equations with brackets; equations with unknowns on both sides
- Sequences: nth term of arithmetic sequences; recognising and generating sequences from the nth term rule
- Linear graphs: plotting y = mx + c; identifying gradient and y-intercept; parallel lines
- Inequalities: representing inequalities on a number line; solving simple linear inequalities
Strand 3 — Geometry and Measure
- Angles in parallel lines: alternate angles, corresponding angles, co-interior angles; applying these in multi-step problems
- Area of a trapezium: applying the formula ½(a+b)h
- Pythagoras' theorem: introduction and application in right-angled triangles
- Transformations: translation, reflection, rotation, and enlargement; describing transformations fully
- Bearings: measuring and calculating three-figure bearings; back bearings
Strand 4 — Statistics and Probability
- Combined probability: listing outcomes systematically; probability of combined independent events
- Tree diagrams: constructing and interpreting tree diagrams for two independent events; using them to find combined probabilities
- Scatter graphs: plotting, interpreting correlation, drawing and using a line of best fit
- Mean from grouped data: calculating an estimate of the mean using midpoints of intervals
How to Structure Stage 8 Practice
A student working through Stage 8 Maths typically benefits more from targeted topic practice than from mixed papers, at least until the main gaps are closed. Mixed papers diagnose the problem; topic practice closes it. Here is a four-step sequence that works for most learners.
- Topic audit first. Before revising anything, identify which topics your child finds difficult — either from a school test result, from teacher feedback, or from working through one question per topic quickly. Start with the topics that appear most often in assessments (Standard Form, angles in parallel lines, equations with brackets, tree diagrams) and the ones where your child already knows they are weak.
- Read a worked example before attempting questions. For topics that are new in Stage 8 (Standard Form, tree diagrams), reading at least one fully worked example before attempting practice questions significantly reduces the frustration of not knowing how to start. A cheat sheet that gives two worked examples side by side is faster than re-reading a chapter of a textbook.
- Timed drill on single-topic questions. After the worked example, work through 15 to 20 questions on that one topic under mild time pressure. Foundation questions should take 2 to 3 minutes each; Standard questions 3 to 5 minutes. Stretch questions are designed to require multi-step thinking. Do not move to the next topic until Foundation and Standard questions feel comfortable.
- Check solutions step by step, not just for the final answer. Cambridge examiners award method marks even when the final answer is wrong. Students who mark their own work by checking the answer only miss the most valuable feedback: where in the working the error occurred. Worked solutions that show every step help a student identify whether their method was right but they made an arithmetic slip, or whether the approach itself was wrong.
What to Practise With
The resource gap for Stage 8 Cambridge Maths is specific: there are general maths resources available, but most are written for UK Key Stage 3 (which overlaps significantly with Stage 8) or for IGCSE (which goes beyond Stage 8 in difficulty and depth). Resources written specifically against Cambridge Lower Secondary syllabus 0862 at Stage 8 level are limited. Official Cambridge Checkpoint past papers cover Stage 8 content but not topic by topic — and the available paper archive is thin.
The Stage 8 topics that most benefit from targeted practice are the ones introduced at this stage or significantly extended from Stage 7. Coremark has published the following Stage 8 Maths boosters, each targeting one specific gap:
Writing large and small numbers in standard form, converting back to ordinary form, ordering in standard form. 20 questions from foundation to stretch with full worked solutions.
Solving equations with brackets and unknowns on both sides; finding and applying the nth term of arithmetic sequences. Two of the most commonly tested Algebra topics at Stage 8.
Alternate, corresponding, and co-interior angles; applying angle rules to multi-step problems with parallel lines and transversals. Includes the complete property cheat sheet.
Combined probability, constructing and reading tree diagrams, finding probabilities of combined independent events. Step-by-step worked examples for every question type.
Each booster is available as a standalone PDF download. If the full Stage 8 Maths picture is what you need, the Stage 8 Maths section at coremark.study lists all available boosters for this stage and subject.

Frequently asked questions
The current Stage 8 Maths boosters cover Standard Form (M·N2), Equations and Sequences (M·A2), Angles in Parallel Lines (M·G1), and Probability and Tree Diagrams (M·S1). These are the four Stage 8 topics that appear most frequently in Cambridge Lower Secondary assessments and where students most commonly need targeted practice. The full Stage 8 catalogue is listed at coremark.study/math.
The Cambridge Lower Secondary Checkpoint Maths assessment has two papers: one with a calculator and one without. Coremark boosters include guidance on whether each question type is typically a non-calculator or calculator topic. Standard Form and Equations questions, for example, are often tested without a calculator, while Statistics questions may allow one. Each booster's guidance section notes which applies.
Every coremark booster contains 20 practice questions, split across three difficulty levels: Foundation (questions 1–7), Standard (questions 8–14), and Stretch (questions 15–20). Foundation questions match the basic level expected at the start of Stage 8. Stretch questions involve multi-step reasoning and match the higher end of what Cambridge Checkpoint tests at Stage 8.
Yes. Coremark boosters are written against the Cambridge Lower Secondary Maths curriculum framework (syllabus 0862), not against any specific textbook. The framework content is the same regardless of which Cambridge-endorsed textbook a school uses — Hodder, Collins, or Cambridge University Press. The booster cheat sheet introduces each topic from first principles, so it works as a standalone resource.
Cambridge Lower Secondary Maths Stage 8 is where the foundations built at Stage 7 are first seriously tested. Standard Form, equations with brackets, angles in parallel lines, and tree diagrams are the topics most likely to need targeted attention.
