NCERT Class 9 maths Ganita Manjari launched with ancient Indian mathematics
NCERT launched the Class 9 maths Ganita Manjari textbook on April 24, 2026 , to be implemented from the 2026-27 academic session . Part 1 runs 196 pages across eight chapters and was developed by a 26-member Textbook Development Team (TDT) .
NCERT Class 9 maths Ganita Manjari — what the book includes
The textbook embeds ancient Indian mathematical systems and historical context into core concepts. It shifts from largely procedural content in earlier editions to contextual and historical learning aligned with NEP 2020 and the National Curriculum Framework 2023 .
The foreword, written by NCERT director Dinesh Prasad Saklani, says the book aims to strengthen mathematical reasoning by linking problems to well-defined historical examples.
NCERT Class 9 maths Ganita Manjari — historical credits and examples
The book credits the Sindhu-Sarasvati civilisation with early "grid-based thinking," citing city streets laid out at uniform distances of 10 metres as an example of a practical coordinate system. It links Baudhayana to what it calls the "Baudhayana-Pythagoras" developments and notes Bhaskara's reference to Ujjayina from around the 4th century BCE .
Brahmagupta is credited with formalising zero and negative numbers as algebraic entities. The Rigveda is cited for contributing to the evolution of the decimal place-value system. Aryabhata's description of pi as "Asanna" (approximate) is framed as an early insight into approximation, while Madhava and the Kerala School (14th century) are credited for infinite series and work on irrational numbers.

Development and alignment
The textbook was prepared by a 26-member TDT and explicitly aligns with NEP 2020 and NCF 2023. The new edition places Indian contributions alongside global developments to provide contextual grounding for topics such as number systems, integers and irrational numbers.
