The Class 8 Mathematics syllabus has changed completely for CBSE session 2026–27. NCERT has replaced the old single-volume textbook with a new two-part series called Ganita Prakash. This guide covers every chapter, every key topic and everything that is different from the previous curriculum — so students, parents and teachers know exactly what to expect this academic year.
Ganita Prakash at a Glance:
| Full Name | Ganita Prakash (गणित प्रकाश) |
| Meaning | Light of Mathematics |
| Prescribed By | NCERT under NCF 2023 |
| Applicable Session | CBSE 2026–27 |

Ganita Prakash is the new official NCERT Mathematics textbook for Class 8, introduced as part of the National Education Policy (NEP) 2020 reforms. It moves away from rote learning and formula memorisation toward conceptual understanding, activity-based exploration and real-life problem solving. Every chapter opens with a story, puzzle or historical reference before introducing any formal mathematics – making the subject feel meaningful rather than mechanical.
The 2026–27 Class 8 Maths syllabus is divided across two volumes as shown below:
| Volume (Chapters) | Broad Topics Covered | When Covered |
|---|---|---|
| Ganita Prakash Part 1 ( Chapters 1 to 7) | Number theory, geometry, mensuration, introductory algebra | First half of session |
| Ganita Prakash Part 2 (Chapters 1 to 7) | Advanced algebra, proportion, Pythagoras theorem, comparing quantities | Second half of session |
| Total (14 Chapters) | Complete Class 8 Mathematics curriculum | Full academic year |
Opening with the puzzle of Queen Ratnamanjuri’s 100 lockers, class 8 Ganita Prakash chapter 1 builds the concept of perfect squares and cubes through pattern discovery rather than direct instruction.
Key Topics Covered:
The paper-folding thought experiment — where 46 folds would reach the Moon — launches 8th Ganita Prakash chapter 2 on exponents and makes abstract ideas instantly vivid.
Key Topics Covered:
A historically grounded chapter tracing number systems from ancient Mesopotamia to India’s own Vedic mathematical tradition.
Key Topics Covered:
A thorough geometry chapter moving from basic polygon theory into the full family of quadrilaterals.
Key Topics Covered:
An introduction to statistics and probability with a strong emphasis on reading and interpreting data, not just drawing graphs.
Key Topics Covered:
One of the most calculation-intensive chapters in Part 1, covering areas, surface areas and volumes of common shapes and solids.
Key Topics Covered:
The algebraic entry point of Part 1, building from what an equation is to solving multi-step equations drawn from word problems.

| Squares and Cubes | Chapters 6 and 7 | Chapter 1 Part 1 and Chapter 3 Part 2 |
| Pythagoras Theorem | Not a dedicated chapter | Full dedicated chapter – Part 2, Chapter 4 |
| Visualising Solid Shapes | Chapter 10 | Removed from syllabus |
| Introduction to Graphs | Chapter 15 | Removed from syllabus |
| Playing with Numbers | Chapter 16 | Removed from syllabus |
| Teaching Approach | Procedural and exercise-focused | Conceptual, activity and story-based |
Key Takeaway:
Three chapters from the old textbook have been removed entirely. The Pythagoras Theorem has been given its own dedicated chapter for the first time. Every remaining topic is now taught with greater emphasis on reasoning and understanding over procedure.
Based on examination weightage, conceptual depth and their importance for Class 9 preparation, these five chapters deserve the most focused study time:
Following a structured approach for each chapter produces far better results than reading through exercises passively. Here are the six steps that work best for the Ganita Prakash curriculum specifically:

When a student encounters a difficult problem in Ganita Prakash, the quality of the resource they turn to makes a real difference. A solution that simply states the answer teaches nothing. A solution that shows every step, explains the reasoning behind each step and connects the working back to the concept being tested — that is what actually builds understanding.
Tiwari Academy’s Class 8 Maths content is built on exactly that principle. Solutions are written for students, not just for teachers. Every step is visible, every method is explained and every answer is aligned with the latest NCERT guidelines for 2026–27. Both English medium and Hindi medium students are fully served, making it one of the very few resources that works equally well for CBSE schools across all states.
Students can access all chapter-wise solutions, MCQs, and PDF downloads for the complete Ganita Prakash syllabus on the Class 8 Maths Solutions page at Tiwari Academy.
Yes. NCERT has prescribed Ganita Prakash Part 1 and Part 2 as the official Class 8 Mathematics textbooks for all CBSE-affiliated schools for session 2026–27. All students under the CBSE board must follow this updated curriculum.
There are 14 chapters in total — 7 in Ganita Prakash Part 1 and 7 in Ganita Prakash Part 2. They cover number systems, geometry, mensuration, algebra, data handling and proportional reasoning.
The most significant addition is a dedicated chapter on the Pythagoras Theorem in Part 2. Power Play (on exponents) and A Story of Numbers (on rational numbers in historical context) are also entirely new in framing and approach compared to their counterparts in the old book.
Three chapters from the old textbook do not appear in the new Ganita Prakash syllabus — Visualising Solid Shapes, Introduction to Graphs and Playing with Numbers.
Algebra Play (Chapter 6, Part 2) is consistently the chapter students find most challenging, followed by Mensuration (Chapter 6, Part 1) and Factorisation (Chapter 7, Part 2).
The old textbook is no longer the prescribed book for this session. However, it remains a useful source of additional practice problems for topics that appear in both the old and new syllabi — particularly rational numbers, algebraic expressions and mensuration.

The Ganita Prakash syllabus gives Class 8 students a genuine opportunity to experience mathematics as a thinking subject – one with history, cultural roots and real-world relevance. Students who engage with the textbook’s stories and activities, not just the exercises, will find the new curriculum more interesting, more memorable and ultimately more rewarding than the old approach.
Understanding the syllabus before the session begins is the first step. The second step is having a reliable resource for when exercises get difficult — one that shows the full working, explains the reasoning, and keeps pace with the CBSE 2026–27 curriculum.
