Power Play

'Power Play' explores exponents and powers — how to write enormous or microscopic numbers compactly using the language of bases and exponents. Master laws of exponents, negative exponents, fractional exponents, scientific notation, and the elegant way mathematics handles numbers as large as the universe and as small as an atom. CBSE Class 8 Maths (Ganita Prakash) Chapter 2.

A Story of Numbers

'A Story of Numbers' traces humanity's journey through natural numbers, integers, rational numbers, and irrational numbers — exploring properties, the number line, and the magnificent Indian contribution to global mathematics (zero, decimal system, Aryabhata, Brahmagupta, Bhaskara). Master rational number operations, decimal expansions, and the place value of India in number-history. CBSE Class 8 Maths (Ganita Prakash) Chapter 3.

Quadrilaterals

'Quadrilaterals' introduces four-sided polygons — parallelograms, rectangles, squares, rhombuses, trapeziums, and kites. Master their properties, angle and side relationships, diagonals, and the five-case construction problem. The chapter blends pure geometry with hands-on construction skills. CBSE Class 8 Maths (Ganita Prakash) Chapter 4.

Proportional Reasoning

'Proportional Reasoning' teaches ratios, proportions, percentages, profit/loss, and simple interest — the practical math that powers daily life, business, and finance. Master direct and inverse proportions, the unitary method, percentage conversions, and the formulas that underlie shopping, salaries, taxes, and banking. CBSE Class 8 Maths (Ganita Prakash) Chapter 7.

The Baudhayana–Pythagoras Theorem

'The Baudhayana-Pythagoras Theorem' explores one of mathematics' most beautiful results — in a right-angled triangle, the square on the hypotenuse equals the sum of squares on the other two sides. Discovered in India by Baudhayana (~800 BCE), proved by Pythagoras (~500 BCE), this theorem underlies geometry, trigonometry, and modern engineering. CBSE Class 8 Maths (Ganita Prakash Part 2) Chapter 9.
