The NCERT Class 8 Ganita Prakash Part II book is the second half of the Class 8 Mathematics textbook, running seven chapters from Fractions in Disguise to Area. The official chapter PDFs are on this page, straight from ncert.nic.in, so you can download the file and start working within a minute.
This page also shows what is actually inside each chapter — the named sections, the page ranges and the question counts, read from the book itself. You can see, before opening any file, which chapter carries the practice load, which builds ideas visually, and which is quick to finish.
Download the NCERT Class 8 Ganita Prakash Part II book PDF
Every file here is NCERT’s own PDF, hosted on ncert.nic.in — the same official edition the textbook page links to. Each row holds one chapter as a separate file, so you can download only the chapter you need instead of the whole book.
The files are named hegp201.pdf to hegp207.pdf on NCERT’s server, so the table doubles as a reference for finding a chapter again.

The maths Class 8 textbook PDF at a glance
Every number below is checkable on this page — the download table lists the chapters and pages, and the chapter directory below lists every section and question.
- Seven chapters, numbered 8–14, because Ganita Prakash for Class 8 is published in two parts — this is Part II.
- 176 printed pages, from Fractions as Percentages (p. 1) to Rectangle and Squares (p. 148).
- 27 named sections across the book and 146 in-text questions in total.
- Practice is unevenly spread — Chapter 8 alone holds 45 of those 146 questions.
- All seven official chapter PDFs are linked above, straight from ncert.nic.in.
- The list further down marks which chapters have a deeper study page on this site.
The book sets no separate activity blocks — practice runs through the in-text questions in each chapter. These counts describe this NCERT textbook alone, not the full CBSE syllabus for Class 8.
What each chapter of the Class 8 maths book contains
| Ch. | Chapter | Sections | Activities | Figures | Questions |
|---|---|---|---|---|---|
| 8 | Fractions in Disguise | 3 | — | — | 45 |
| 9 | The Baudhāyana-Pythagoras Theorem | 7 | — | — | 16 |
| 10 | Proportional Reasoning-2 | 6 | — | — | 22 |
| 11 | Exploring Some Geometric Themes | 2 | — | — | 18 |
| 12 | Tales by Dots and Lines | 2 | — | — | 14 |
| 13 | Algebra Play | 6 | — | — | 12 |
| 14 | Area | 1 | — | — | 19 |
Use the directory above to check any chapter’s section, activity and question counts. A section is one of NCERT’s own numbered headings; an activity is a hands-on task the book sets — every chapter lists 0, so the practice load sits in the question column; a question is an in-text exercise.
Do not look for a figure column: this book prints its diagrams without captions, so there is no separate figure index for it.
Chapter 8: Fractions in Disguise (pp. 1–32)
This chapter teaches percentages as fractions with denominator 100 — \( x\% = \frac{x}{100} \) — across three sections: Fractions as Percentages (p. 1), Percentage of Some Quantity (p. 6) and Using Percentages (p. 14).
With 45 of the book’s 146 in-text questions, it carries the heaviest practice load of the seven chapters and is the natural starting point for anyone who finds percentage problems slow.
Chapter 9: The Baudhāyana-Pythagoras Theorem (pp. 33–54)
Chapter 9 develops the Baudhāyana-Pythagoras theorem — the relation among the three sides of a right-angled triangle — by first doubling a square (p. 33) and halving a square (p. 36) before reaching right-triangles having integer sidelengths (p. 48).
Its 16 questions practise the theorem directly, and the visual build-up makes it the chapter for students who find an abstract formula hard to hold onto.
Chapter 10: Proportional Reasoning-2 (pp. 55–69)
This chapter continues the proportionality strand from earlier classwork — the 2 in its title signals that.
From Proportionality—A Quick Recap (p. 55) it moves to Ratios in Maps (p. 56), Ratios with More than 2 Terms (p. 57), Dividing a Whole in a Given Ratio (p. 58), A Slice of the Pie (p. 60) and Inverse Proportions (p. 63) — 22 questions that pair naturally with the percentage work of Chapter 8.
Chapter 11: Exploring Some Geometric Themes (pp. 70–102)
At 33 pages this is the longest chapter in the book, and it reads as exploration rather than drill.
Fractals (p. 70) introduces self-similar patterns such as the Sierpinski Carpet, Sierpinski Gasket and Koch Snowflake, while Visualising Solids (p. 75) turns to shapes in space — a good fit for students who learn best from patterns and shapes, with 18 questions.
Chapter 12: Tales by Dots and Lines (pp. 103–134)
This is the book’s statistics chapter.
The Balancing Act (p. 103) treats the mean as a balance point — the sum of the distances of the values to its left equals the sum to its right — and Visualising and Interpreting Data (p. 116) moves on to graphs and data displays, with 14 questions, essential for anyone going further into data handling.
Chapter 13: Algebra Play (pp. 135–147)
At 13 pages and 12 questions, this is the shortest chapter in the book, and it builds algebraic thinking through play.
‘Think of a number’ tricks (p. 135), number pyramids (p. 137), fun with grids (p. 141), the largest product (p. 142) and decoding divisibility tricks (p. 144) — the chapter to finish fast before revision.
Chapter 14: Area (pp. 148–176)
The final chapter gathers the area formulas under one heading, Rectangle and Squares (p. 148): the triangle as \( \frac{1}{2} \times \text{base} \times \text{height} \), polygons split into triangles, the parallelogram as \( \text{base} \times \text{height} \), and the rhombus formula.
Its 19 questions fix the formulas, and the chapter builds directly on the square and triangle work of Chapter 9.

How to use the Class 8 math book PDF for study
A sensible order of work for this book, naming chapters as you go:
- Chapter 8: Fractions in Disguise first — 45 questions make it the practice anchor of the book, and its percentage work returns in Chapters 10 and 12.
- Chapter 10: Proportional Reasoning-2 second — it reuses ratio and percentage ideas and adds maps, pie charts and inverse proportions.
- Chapter 9: The Baudhāyana-Pythagoras Theorem before Chapter 14: Area — the square-and-triangle reasoning in Chapter 9 feeds the area formulas of Chapter 14.
- Then the shorter standalone chapters in any order: Chapter 13: Algebra Play finishes fast, and Chapters 12 and 11 can follow whenever you want a change of topic.
The kind of practice differs sharply between chapters, which is worth knowing when you plan a session:
| Chapter | Kind of practice |
|---|---|
| 8. Fractions in Disguise | Numerical percentage work |
| 9. The Baudhāyana-Pythagoras Theorem | Geometric reasoning with squares and triangles |
| 10. Proportional Reasoning-2 | Ratio-and-proportion setup problems |
| 11. Exploring Some Geometric Themes | Visual pattern-building |
| 12. Tales by Dots and Lines | Reading and interpreting data |
| 13. Algebra Play | Algebraic pattern-spotting and justification |
| 14. Area | Applying area formulas |

Where is the Pythagoras theorem taught in this book?
In Chapter 9, The Baudhāyana-Pythagoras Theorem (pp. 33–54). The chapter builds the theorem visually — doubling and halving squares first, then integer sidelengths — before its applications.
Which chapter should a student read first in Ganita Prakash Part II?
Chapter 8, Fractions in Disguise. Its percentage work carries the heaviest practice load in the book and returns in Chapters 10 and 12, so it is the natural starting point.
