The CBSE Class 10 Maths Syllabus 2027 for the 2026–27 academic session covers seven units: Number Systems, Algebra, Coordinate Geometry, Geometry, Trigonometry, Mensuration, and Statistics and Probability. The Central Board of Secondary Education (CBSE) has prescribed an 80-mark theory examination and 20 marks for internal assessment, making the total Mathematics score 100 marks.

The syllabus includes 14 chapter areas across the seven units, covering topics such as quadratic equations, arithmetic progressions, similar triangles, trigonometric identities, surface areas and volumes, and probability. Algebra carries the highest unit-wise weightage at 20 marks, followed by Geometry at 15 marks.

CBSE offers two Mathematics options for Class 10: Mathematics Standard (Code 041) and Mathematics Basic (Code 241). Both follow the same course structure, but their question-paper designs differ in the balance of recall, understanding, application, and higher-order thinking questions.

CBSE Class 10 Maths Syllabus Chapter-Wise Weightage 2027

The CBSE Class 10 Maths syllabus 2027 is divided into seven units, with each unit carrying a specific number of marks in the 80 mark theory paper. Students can use the unit wise marks distribution to understand the weightage of each section and plan their preparation accordingly.

Unit	Unit Name	Marks	Share of Theory
I	Number Systems	6	7.5%
II	Algebra	20	25%
III	Coordinate Geometry	6	7.5%
IV	Geometry	15	18.75%
V	Trigonometry	12	15%
VI	Mensuration	10	12.5%
VII	Statistics and Probability	11	13.75%
Total		80	100%

CBSE Class 10 Maths Exam Pattern 2027

The official CBSE curriculum specifies a 3 hour, 80 mark theory examination for both Mathematics Standard and Mathematics Basic. The remaining 20 marks are assessed internally.

Mathematics Standard: Question Paper Design

Question Typology	Marks	Approx. Weightage
Remembering and Understanding	43	54%
Applying	19	24%
Analysing, Evaluating and Creating	18	22%
Total	80	100%

Mathematics Basic: Question Paper Design

Question Typology	Marks	Approx. Weightage
Remembering and Understanding	60	75%
Applying	12	15%
Analysing, Evaluating and Creating	8	10%
Total	80	100%

The Mathematics Standard paper has a greater proportion of application-based and higher-order questions than the Mathematics Basic paper. Students should practise according to their chosen course rather than assuming the two papers have identical difficulty levels.

CBSE Class 10 Maths Internal Assessment 2027

Mathematics has 20 marks for internal assessment, which are added to the 80-mark theory examination. The lab practical component is based on activities from the prescribed books.

Component	Marks
Pen Paper Test and Multiple Assessment	10
Portfolio	5
Lab Practical	5
Total	20

The pen-paper and multiple-assessment component accounts for 10 marks combined. Laboratory practical work is based on activities from the prescribed books.

CBSE Class 10 Maths Standard vs Basic Syllabus

CBSE's 2027 Mathematics curriculum lists Mathematics Standard (Code 041) and Mathematics Basic (Code 241). The course structure is presented together in the curriculum document, while separate question paper designs are provided for the two codes.

The major difference visible in the official question paper design is the distribution of cognitive categories:

Category	Mathematics Standard	Mathematics Basic
Remembering & Understanding	54%	75%
Applying	24%	15%
Analysing, Evaluating & Creating	22%	10%

Has the CBSE Class 10 Maths Syllabus Changed in 2026–27?

CBSE has published a Mathematics curriculum for the 2026–27 academic session. The document describes a focus on conceptual understanding, logical reasoning, problem-solving, real-life applications and competency-based learning. The current curriculum lists seven units and specifies their marks distribution, detailed topics, question-paper designs and internal assessment structure.

However, a change in the curriculum's stated emphasis does not, by itself, establish that every chapter or topic is new. Students comparing the 2026–27 syllabus with the previous session should check the prescribed topics and exclusions in both curriculum documents rather than relying on unverified lists of deleted or added chapters. For the 2027 examination, the 2026–27 curriculum is the relevant syllabus document.
