If your child is in Class 9 this year, their maths looks different from what older siblings studied. CBSE has redesigned the Class 9 Mathematics curriculum for 2026–27, NCERT has published a new textbook, and there is a new optional Mathematics Advanced paper. Here is what has changed, from the official CBSE curriculum and NCERT's textbook pages.
The full unit table and sources are on our CBSE Class 9 Maths guide.
The new units and marks
The Class 9 year-end theory paper is 80 marks and 3 hours, set by the school. The units are:
- Number System – 7 marks
- Algebra – 20 marks
- Coordinate Geometry – 4 marks
- Geometry – 25 marks
- Mensuration – 14 marks
- Statistics and Probability – 10 marks
Internal assessment adds 20 marks: pen-and-paper tests and multiple assessment (5 + 5), a portfolio (5) and lab activities (5).
Geometry and Algebra together make up 45 of the 80 theory marks.
The new textbook: Ganita Manjari
NCERT's current Class 9 Mathematics textbook is Ganita Manjari, published in two parts. Its chapter titles are written in a new style – for example "The World of Numbers", "Orienting Yourself: The Use of Coordinates", "The Mathematics of Maybe: Introduction to Probability" and "Propositions and their Converses".
One practical point for parents: the book's chapter titles do not match the curriculum's chapter names one-to-one, and no official mapping between them has been published. When a school worksheet refers to a curriculum topic (say, "Lines and Angles"), it helps to check with the teacher which book chapter it corresponds to.
New topics in Class 9
The redesigned curriculum brings in topics that many families associate with later classes, including:
- sequences and progressions – arithmetic and geometric progressions, with examples such as the Tower of Hanoi and fractals
- slope and intercept of a line
- pairs of linear equations, solved by substitution and elimination
- the midpoint theorem and medians
- propositions and converses – reasoning about whether a statement and its converse are both true
- an introduction to probability
A quick example: statement and converse
"If a quadrilateral is a square, then its diagonals are equal" is true. Its converse – "If a quadrilateral's diagonals are equal, then it is a square" – is false: a rectangle has equal diagonals but need not be a square. Recognising this kind of reasoning is now part of Class 9 maths.
The optional Mathematics Advanced paper
From 2026–27, Class 9 students can also opt for Mathematics at Advanced Level:
- it is extra content, assessed by a separate 25-mark, 1-hour paper of higher-order questions
- its marks are not added to the student's aggregate
- a student who scores 50% or more gets a note on the marksheet (CBSE describes this wording as tentative)
- its study material covers six chapters: sets, logarithms, relations and functions, coordinate geometry, combinatorics, and further progressions
- for Class 10, the Advanced paper becomes a board examination from 2027–28
It suits students who enjoy maths and want more challenge – particularly those likely to take mathematics in Class 11.
How parents can help this year
- Ask for the book-to-curriculum mapping your child's school uses, so homework and revision line up.
- Watch geometry and algebra closely – they are 45 of the 80 marks.
- Keep the internal assessment on track – the portfolio and lab activities are 10 of the 20 internal marks.
- Decide on Mathematics Advanced early in the year if your child is interested.

Frequently asked questions
- What is Ganita Manjari?
- Ganita Manjari is NCERT's current Class 9 Mathematics textbook, published in two parts. Its chapter titles differ from the names used in the CBSE curriculum.
- Is Class 9 maths a board exam?
- No. The Class 9 year-end exam is set by the school: 80 marks of theory and 20 marks of internal assessment.
- What is CBSE Mathematics Advanced in Class 9?
- An optional extra paper of 25 marks and 1 hour with higher-order questions. Its marks are not added to the aggregate; scoring 50% or more earns a note on the marksheet.
