CBSE Class 10 Maths Syllabus Unit-wise 2025

To effectively understand the CBSE Class 10 Maths Syllabus, it is important to understand the structure and key components. The Class 10 maths syllabus is divided into distinct units, each addressing specific maths chapters, and is designed for a theory paper of 80 marks, and 20 marks allocated for internal assessment.

CBSE Class 10 Maths Chapters 2025

The CBSE Class 10 maths syllabus is organised into 7 units, which are further divided into 15 chapters. A detailed list of these CBSE 10th maths chapters is provided below. To ensure a smooth learning process and avoid last-minute stress, students are advised to begin their preparation early and maintain a consistent study schedule.

Unit 1: Number Systems

1. Real Number

Fundamental Theorem of Arithmetic - statements after reviewing work done earlier and after illustrating and motivating through examples, Proofs of irrationality of √2, √3, √5

Unit 2: Algebra

1. Polynomials

Zeros of a polynomial. Relationship between zeros and coefficients of quadratic polynomials.

2. Pair of linear equations in two variables

Pair of linear equations in two variables and graphical method of their solution, consistency/inconsistency.

Algebraic conditions for number of solutions. Solution of a pair of linear equations in two variables algebraically - by substitution, by elimination. Simple situational problems.

3. Quadratic equations

Standard form of a quadratic equation ax2 + bx + c = 0, (a ≠ 0). Solutions of quadratic equations (only real roots) by factorization, and by using quadratic formula.

Relationship between discriminant and nature of roots. Situational problems based on quadratic equations related to day to day activities to be incorporated.

4. Arthimetic progressions

Motivation for studying Arithmetic Progression Derivation of the nth term and sum of the first n terms of A.P. and their application in solving daily life problems.

UNIT 3: Coordinate Geometry

1. Coordinate Geometry

Review: Concepts of coordinate geometry, graphs of linear equations. Distance formula. Section formula (internal division).

UNIT 4: Geometry

1. Triangles

Definitions, examples, counter examples of similar triangles.

1. (Prove) If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio.

2. (Motivate) If a line divides two sides of a triangle in the same ratio, the line is parallel to the third side.

3. (Motivate) If in two triangles, the corresponding angles are equal, their corresponding sides are proportional and the triangles are similar.

4. (Motivate) If the corresponding sides of two triangles are proportional, their corresponding angles are equal and the two triangles are similar.

5. (Motivate) If one angle of a triangle is equal to one angle of another triangle and the sides including these angles are proportional, the two triangles are similar.

2. Circles

Tangent to a circle at, point of contact

1. (Prove) The tangent at any point of a circle is perpendicular to the radius through the point of contact.

2. (Prove) The lengths of tangents drawn from an external point to a circle are equal.

UNIT 5: Trignometry

1. Introduction to trigonometry

Trigonometric ratios of an acute angle of a right-angled triangle. Proof of their existence (well defined); motivate the ratios whichever are defined at 0o and 90o. Values of the trigonometric ratios of 300, 450 and 600. Relationships between the ratios.

2. Trignometric identities

Proof and applications of the identity sin2A + cos2A = 1. Only simple identities to be given.

3. Heights and distances: Angle of elevation, Angle of Depression.

Simple problems on heights and distances. Problems should not involve more than two right triangles. Angles of elevation/depression should be only 30°, 45°, and 60°.

UNIT 6: Mensuration

1. Areas related to circles

Area of sectors and segments of a circle. Problems based on areas and perimeter/circumference of the above-said plane figures. (In calculating area of segment of a circle, problems should be restricted to central angle of 60°, 90° and 120° only.

2. Surface areas and volumes

Surface areas and volumes of combinations of any two of the following: cubes, cuboids, spheres, hemispheres and right circular cylinders/cones.

UNIT 7: Statistics and Probability

1. Statistics

Mean, median, and mode of grouped data (bimodal situation to be avoided).

2. Probability

Classical definition of probability. Simple problems on finding the probability of an event.

Preparation Tips for CBSE Class 10 Maths

The 2025 10th board exams are now over, and the new academic year for 2026 is about to begin. To get a head start, students should begin their preparations immediately. A manageable strategy is to tackle two chapters each month, ensuring thorough understanding through consistent revision. Additional preparation tips are provided below.

Check the CBSE 10 maths syllabus and exam pattern:

• Thoroughly review the official CBSE Class 10 syllabus.

• Familiarise yourself with the maths exam pattern, including the number of sections, types of questions, and CBSE 10th marking scheme.

• Pay attention to the weightage of each unit or chapter.

Create a study schedule:

• Develop a realistic study timetable, allocating sufficient time to each topic.

• There are a total of 15 chapters, divide each chapter according to the time left to you

• Prioritise challenging areas and allocate more time to them.

• Ensure regular breaks to avoid burnout.

Fundamentals must be strong:

• Strengthen your understanding of basic concepts and formulas.

• Focus on building a strong foundation, as it will make tackling complex problems easier.

Maths is all about Practice:

• Solve a variety of problems from maths textbooks, CBSE 10th sample papers, and previous years' question papers.

• Practice different types of questions, including MCQs, short answers, and long answers.

• Solve sample papers and take mock tests to simulate the actual exam environment.

• Analyse your performance in mock tests to identify areas needing improvement.

Focus on NCERT Textbooks:

• NCERT textbooks are the primary resource for the CBSE Class 10 Maths exam.

• Ensure you have thoroughly studied and understood all the concepts and exercises in the NCERT textbooks.

• Prioritise practicing all NCERT examples and exercises. Never underestimate the value of NCERT textbooks; they are designed for easy understanding and CBSE 10th maths syllabus is focused on them.

Solve previous years' question papers:

• Solving CBSE 10th previous years' question papers helps you understand the exam pattern and the types of questions asked.

• It also helps to identify the strengths and weaknesses.

• Practice solving them within the stipulated time to improve your speed and accuracy.
