Tamil Nadu Class 10 Maths — Samacheer Kalvi Complete Guide 2026

The Tamil Nadu SSLC board examination is one of the most significant academic milestones for students across the state. Lakhs of students appear for the exam every year, and a strong score in Mathematics is essential for admission to engineering, medicine, and polytechnic streams.

The Samacheer Kalvi syllabus is designed by the Tamil Nadu Textbook and Educational Services Corporation. It covers 8 well-structured chapters spanning algebra, geometry, trigonometry, mensuration, and statistics. Whether you study in Tamil medium or English medium, the mathematical concepts are identical.

SparkEd now offers complete, free support for TN Board Class 10 students — practice questions, downloadable worksheets, step-by-step solutions, and an AI math coach that works around the clock.

Here is a detailed look at each chapter in the Samacheer Kalvi Class 10 Mathematics syllabus:

Chapter 1: Relations and Functions
Cartesian product of sets, arrow diagrams, types of functions (one-one, onto, bijection), and composition of functions. This chapter builds the foundation for algebraic thinking.

Chapter 2: Numbers and Sequences
Euclid's division algorithm, modular arithmetic, arithmetic progressions (AP), geometric progressions (GP), and special series ($\sum n$, $\sum n^2$, $\sum n^3$). A high-weightage chapter.

Chapter 3: Algebra
GCD and LCM of polynomials, solving quadratic equations by factorisation and formula, matrices — types, operations, and determinants. This is often the most challenging chapter.

Chapter 4: Geometry
Similar triangles, Basic Proportionality Theorem (BPT), tangent properties of circles, and concurrency theorems (centroid, orthocentre, circumcentre). Requires careful practice with proofs.

Chapter 5: Coordinate Geometry
Area of a triangle using coordinates, equations of straight lines, slope and intercept form, and the section formula.

Chapter 6: Trigonometry
Trigonometric identities and their proofs, and applications involving heights and distances. Highly scoring if formulas are well-practised.

Chapter 7: Mensuration
Surface area and volume of combined solids, frustum of a cone, and conversion between solids. Requires strong visualisation skills.

Chapter 8: Statistics and Probability
Mean, median, and mode for grouped data, standard deviation, coefficient of variation, and basic probability. The most straightforward chapter for most students.
