NCERT Class 8 Maths Book PDF

NCERT Class 8 Maths Chapter 1 (Ganita Prakash) introduces students to square numbers and cube numbers — their patterns, properties, and how to find square roots and cube roots. This CBSE chapter builds number sense by exploring why certain numbers are 'perfect' squares or cubes, using visual models and patterns. Students learn shortcut methods and real-world applications of these concepts.

NCERT Class 8 Maths Chapter 2 (Ganita Prakash) explores powers and exponents — the compact notation for representing very large and very small numbers. This CBSE chapter covers laws of exponents, negative exponents, zero exponent, and standard form (scientific notation). Students learn to simplify expressions involving powers and understand applications in science and technology where extreme numbers appear.

NCERT Class 8 Maths Chapter 3 (Ganita Prakash) takes students on a journey through the number system — from natural numbers to integers, fractions, and rational numbers. This CBSE chapter helps students understand the properties of rational numbers, their representation on a number line, and operations on them. The chapter builds a deep conceptual foundation rather than just procedural calculation skills.

NCERT Class 8 Maths Chapter 4 (Ganita Prakash) explores quadrilaterals — four-sided polygons — their properties, classification, and special types. This CBSE chapter covers parallelograms, rectangles, rhombuses, squares, trapeziums, and kites, explaining the unique properties of each. Students learn to prove properties using angle-sum relationships and use these in solving geometric problems.

NCERT Class 8 Maths Chapter 5 (Ganita Prakash) is an exploration of interesting number patterns, puzzles, and properties that make mathematics playful and curious. This CBSE chapter covers divisibility tests, interesting number sequences, games with numbers, and patterns in multiplication and addition. It develops mathematical thinking and problem-solving skills through exploration rather than rote computation.

NCERT Class 8 Maths Chapter 6 (Ganita Prakash) explores the distributive law and how it connects multiplication with addition and subtraction. This CBSE chapter demonstrates how distribution is a fundamental algebraic principle that underlies operations in arithmetic and algebra, including simplification of expressions and expansion of brackets. Students understand why mathematical rules work, not just how to apply them.

NCERT Class 8 Maths Chapter 7 (Ganita Prakash Part 1) introduces proportional reasoning — understanding how two quantities relate and vary together. This CBSE chapter covers direct proportion, ratios, and their applications in real-world problem-solving involving maps, scales, recipes, speed, and pricing. Students develop the crucial skill of identifying whether two quantities are in proportion and solving proportional problems efficiently.

NCERT Class 8 Maths Chapter 8 (Ganita Prakash Part 2) explores percentages, discounts, profit and loss, and simple interest — all of which are applications of fractions. This CBSE chapter helps students recognise fractions hidden in everyday financial and commercial contexts, developing real-world problem-solving skills. Students learn to calculate percentages, compare quantities, and understand basic financial literacy.

NCERT Class 8 Maths Chapter 9 (Ganita Prakash Part 2) explores one of the most famous theorems in mathematics — the relationship between the sides of a right-angled triangle. This CBSE chapter honours the ancient Indian mathematician Baudhāyana, who stated this result before Pythagoras. Students learn to apply the theorem to find unknown sides, verify right angles, and solve real-world problems involving distances and heights.

NCERT Class 8 Maths Chapter 10 (Ganita Prakash Part 2) extends proportional reasoning to inverse proportion and its applications. This CBSE chapter covers how to identify and solve problems where quantities are inversely related — when one increases, the other decreases proportionally. Real-world applications include speed-time problems, work-time problems, and resource allocation.

NCERT Class 8 Maths Chapter 11 (Ganita Prakash Part 2) delves deeper into geometry, exploring the properties of shapes, symmetry, geometric constructions, and transformations. This CBSE chapter builds spatial reasoning skills and helps students see mathematics in architecture, art, and nature. Topics include lines, angles, special triangles, and the properties of circles.

NCERT Class 8 Maths Chapter 12 (Ganita Prakash Part 2) introduces students to the basics of graph theory and coordinate geometry — how mathematical relationships can be visualised as points (dots) and connections (lines) on a plane or graph. This CBSE chapter covers plotting points, drawing and interpreting graphs, and using graphs to solve problems in science and everyday life.

NCERT Class 8 Maths Chapter 13 (Ganita Prakash Part 2) makes algebra engaging through exploration of expressions, equations, and patterns. This CBSE chapter covers simplifying algebraic expressions, forming and solving linear equations, and understanding the power of algebra in generalising mathematical patterns. Students move from specific numbers to general rules — a key leap in mathematical thinking.

NCERT Class 8 Maths Chapter 14 (Ganita Prakash Part 2) provides a comprehensive treatment of area — how to measure the two-dimensional space enclosed by various shapes including triangles, quadrilaterals, and circles. This CBSE chapter connects geometry with arithmetic, developing formulae from first principles and applying them to complex composite figures. Students solve practical problems involving land measurement, floor plans, and surface areas.
