ICSE Classes 8-10
ICSE Mathematics (8-10)
ICSE Mathematics for Classes 8 to 10 builds arithmetic, algebra, geometry, mensuration, trigonometry, statistics, and problem-solving skills. These notes focus on clear steps and regular practice.
Chapter-wise and Topic-wise List
Use this as a checklist while studying from your school textbook, teacher notes, and the latest CISCE syllabus shared by your school.
- Rational numbers
- Linear equations
- Commercial mathematics
- Algebraic expressions
- Factorisation
- Indices and surds
- Quadratic equations
- Coordinate geometry
- Triangles and circles
- Mensuration
- Trigonometry
- Statistics
- Probability
- Graphs
- Word problems
Important Concepts
- Understand the rule before solving a set of questions.
- Show steps clearly because method marks are important.
- In geometry, draw a figure and mark given information first.
- For word problems, define variables before forming equations.
- Revise formulas daily and practise mixed questions weekly.
Important Definitions
| Variable | A symbol representing an unknown or changing number. |
|---|
| Equation | A statement showing equality of two expressions. |
|---|
| Polynomial | An algebraic expression with non-negative integer powers of variables. |
|---|
| Congruence | Exact equality of shape and size. |
|---|
| Probability | Measure of chance of an event. |

Key Formulas and Facts
Write formulas with units and conditions. In ICSE/ISC answers, a correct formula plus clear substitution improves presentation.
Solved Example
Solve 2x + 7 = 19.
Subtract 7 from both sides: 2x = 12. Divide by 2: x = 6. Check: 2(6) + 7 = 19.
Important Diagrams
Practise diagrams for triangles, quadrilaterals, circles, coordinate axes, graphs, histograms, cuboids, cylinders, cones, and trigonometric right triangles.
Practice Questions
- Solve ten linear equation questions.
- Find area and volume of common solids.
- Prove one geometry result with reasons.
- Make a formula chart for mensuration.
- Solve five statistics questions using tables.

Chapter Summary
ICSE Mathematics (8-10) helps students build concept clarity, accurate terminology, and strong answer-writing habits. Study the syllabus topics first, practise specimen-paper style questions, and revise definitions, diagrams, and formulas together.
Revision Points
- Read the latest CISCE syllabus shared by your school before final revision.
- Make short notes chapter-wise and mark definitions, formulas, diagrams, and examples.
- Practise writing answers within time limits.
- Use neat headings, labelled diagrams, correct units, and important keywords.
- Revise mistakes from tests instead of only re-reading notes.
Common Mistakes to Avoid
- Using CBSE-only chapter order without checking the ICSE/ISC syllabus.
- Writing very long answers without the exact keyword required.
- Skipping diagrams, formulas, units, and labelled steps.
- Practising only objective questions and ignoring written answers.
- Using old specimen papers without checking whether the pattern has changed.
