NCERT Class 9 Ganita Manjari Book — What’s Inside Each Chapter

The NCERT Class 9 Ganita Manjari book is the official Mathematics textbook for Class 9, published by NCERT and used in CBSE schools. This page hands you all 8 chapter PDFs in one table, then says what each chapter teaches — named sections, indexed figures and exercise questions — so you can find your chapter without opening every file.

CBSE sets the syllabus; NCERT publishes the book. The chapter-by-chapter breakdown below is measured from the book itself, not copied from a syllabus list — and it tells you where the work actually sits.

Download the official chapter-wise PDFs (NCERT, ncert.nic.in)

These are NCERT’s own files, hosted on the official NCERT textbook portal (ncert.nic.in/textbook.php) and free to download, so the links below go straight to the official edition. Every chapter of the Class 9 Mathematics textbook is a separate PDF.

Two chapters, 2 and 4, are printed with the simple title “Introduction”; each is a full chapter in its own right.

What’s inside each chapter of the Class 9 Maths book

Each chapter’s counts, measured from the book itself, in one row:

What the columns count: a section is one of NCERT’s own numbered headings; a figure is a numbered figure indexed from the book; a question is an end-of-chapter exercise; an activity is a numbered activity — this book has none.

Figure images are not reproduced on this page; the figures appear as indexed captions, and the diagrams live in the official PDFs above.

Reading the counts, three things stand out before you open a single PDF:

• The geometry chapters carry the diagrams. Chapter 6 holds 30 of the book’s 67 indexed figures and Chapter 5 another 11 — together nearly three-fifths of the diagrams. These two chapters must be revised with the PDF open.
• The exercise load concentrates in Chapters 2, 3 and 6. Chapters 2 and 6 each end with 25 questions, while Chapter 3’s 24 questions split into 42 parts, the most in the book.
• Chapter 3 is the densest in structure. Its 19 named sections across 27 pages carry the whole history of number, from the Ishango bone to cyclic decimals.
• Chapters 4 and 7 are the lightest, at 12 questions each — useful for a first pass when you need a quick win.

Chapter 3 also holds a history thread you will not find on a solutions site:

• The Ishango bone and its prime-number tally groupings — indexed as Figure 3.1.
• The Bakhshālī manuscript and Brahmagupta’s rules for zero, inside the revolution of śhūnya.
• Madhava’s infinite series for \( \pi \), closing the story of pi.
• The square root spiral (Figure 3.14) — the construction that ends the section on irrational lengths.

Chapter 1: Orienting Yourself: The Use of Coordinates (15 pages)

For students meeting coordinate geometry for the first time, this chapter sets up the 2-D Cartesian coordinate system, practises plotting and reading points, then ends with the distance between two points — 4 named sections, 2 indexed figures, 12 questions.

Chapter 2: Introduction (25 pages)

Despite the plain title, this is the first algebra chapter: linear polynomials treated as input-output processes, exploring linear patterns, linear relationships, and visualising linear relationships on graphs — 5 named sections, 3 indexed figures, 25 questions (41 parts, the second-highest part count in the book).

Chapter 3: The Dawn of Mathematics: the Human Need to Count (27 pages)

This is the number-system chapter told through history. It runs from the Ishango bone, through the revolution of śhūnya (zero), the Bakhshālī manuscript and Brahmagupta’s rules, to integers and fractions — then into irrational numbers: the proof that \( \sqrt{2} \) is irrational, the construction of lengths like \( \sqrt{n} \), and the square root spiral.

It ends with real numbers as decimals, cyclic numbers, and the story of pi and Madhava’s infinite series — 19 named sections, 4 indexed figures, 24 questions (42 parts, the most in the book).

Chapter 4: Introduction (24 pages)

Again the title hides the content: this is the second algebra chapter, covering visualising identities geometrically, factorisation of algebraic expressions using identities, factorisation with and without algebra tiles, finding new identities, and simplifying rational expressions — 7 named sections, 4 indexed figures, 12 questions (35 parts).

Chapter 5: I’m Up and Down, and Round and Round (26 pages)

The circles geometry chapter: definitions, symmetries of a circle, how many circles pass through given points (including the circumcircle, whose centre falls outside an obtuse triangle and at the midpoint of the hypotenuse of a right triangle), chords and the angles they subtend, and concyclicity of points — 10 named sections, 11 indexed figures, 17 questions.

Chapter 6: Measuring Space: Perimeter and Area (37 pages)

The longest chapter and where most diagram revision sits: perimeter of a shape and of a circle (the \( C/D \) ratio), why \( \pi \) is irrational, length of an arc, then area of a rectangle, parallelogram, triangle and circle, Heron’s formula, and the area of a sector — 12 named sections, 30 of the book’s 67 indexed figures, 25 questions.

Chapter 7: The Mathematics of Maybe: Introduction to Probability (19 pages)

Probability in plain language: what probability is, randomness, the probability scale, experimental and theoretical probability, sample spaces and events, and tree diagrams — 11 named sections, 5 indexed figures (including a 19th-century Jain Jñān-Chaupad game from the National Museum), 12 questions (28 parts).

Chapter 8: Predicting What Comes Next: Exploring Sequences and Progressions (27 pages)

Sequences and progressions: explicit and recursive rules for a sequence, arithmetic progressions, the sum of the first \( n \) natural numbers, and geometric progressions (with fractals).

The book’s figures show the difference: points from an AP lie on a straight line (Figure 8.4, “Growing pattern of squares represented by a linear pattern”) while points from a GP do not (Figure 8.9) — 9 named sections, 8 indexed figures, 19 questions.

Study pages for the individual chapters

The table below is the honest current state of the per-chapter study pages: every chapter is named, and none has a study page yet.

How to use the Class 9 Maths NCERT book

Here is a study order for this book, based on the counts above.

1. Start with Chapters 1 and 3 — they build tools the later chapters use. Chapter 1’s coordinate plane is the stage for every graph in Chapters 2 and 8; Chapter 3’s proof that \( \sqrt{2} \) is irrational is the mathematical habit the rest of the book assumes.
2. Then the algebra strand: Chapters 2 and 4, in that order — Chapter 2’s linear relationships feed directly into Chapter 4’s identities and factorisation.
3. Then the geometry strand: Chapters 5 and 6 — circle properties from Chapter 5 feed the perimeter and area work of Chapter 6. Both are figure-heavy (11 and 30 indexed figures), so keep the chapter PDF open while you read.
4. Chapters 7 and 8 are the most self-contained — probability and sequences can each be revised independently, in either order.

One caution: textbook contents and the examinable syllabus are not always identical — check the current official syllabus for what is examinable this session.

And one mistake to name before you make it: do not find the area of a four-sided figure from its side lengths alone. The book itself warns about this — Figure 6.27 carries the caption “The area of a 4-gon cannot be found only from the lengths of its sides”.

Two places on this site help you place this book in context. The Class 9 NCERT books hub lists every Class 9 subject this site indexes, not just Mathematics.

The NCERT books index by class covers the whole shelf, from the primary classes up. When you finish Class 9, the Class 10 NCERT books hub is where the next year of the same subjects begins.
