Mathematics — Class 8

CBSE (Indian Curriculum) · Ages 13-14

CBSE Class 8 Mathematics is the last year before the board syllabus begins, and the algebra taught here underpins everything in Classes 9 and 10. Students work with rational numbers, linear equations in one variable, algebraic expressions and identities, and factorisation.

New topics include squares and square roots, cubes and cube roots, exponents including negative powers, direct and inverse proportion, understanding quadrilaterals, mensuration of solids, and an introduction to graphs.

Key topics covered

• Rational Numbers — Properties, operations and representation on the number line.
• Linear Equations — Solving equations in one variable and forming them from problems.
• Algebraic Expressions & Identities — Multiplication of expressions, standard identities and factorisation.
• Squares, Cubes & Exponents — Square and cube roots, laws of exponents and negative powers.
• Comparing Quantities — Compound interest, discount, and direct and inverse proportion.
• Geometry & Mensuration — Quadrilaterals, constructions, surface area and volume of solids.
• Data Handling & Graphs — Grouped data, histograms, pie charts, probability and linear graphs.
