Chapter-Wise Important Questions for 10th Mathematics — Tamil Nadu State Board
Why Chapter-Wise Preparation Is the Key to Scoring High
Mathematics is a subject where systematic, chapter-by-chapter preparation outperforms random studying every single time. Each chapter in the 10th standard Mathematics syllabus builds on specific concepts and has distinct question types that appear in the public examination. By identifying and practising the most important questions from each chapter, you can ensure comprehensive coverage of the entire syllabus while focusing your energy on what matters most. Om Muruga Publication has conducted extensive analysis of previous year papers to identify the highest-value questions from every chapter.
Chapters 1 and 2 — Relations, Functions, Numbers and Sequences
Chapter 1 introduces foundational concepts of ordered pairs, Cartesian products, relations, and functions. Important question types include identifying whether a relation is a function, finding the domain and range, and arrow diagram-based problems. Typically 5 to 8 marks come from this chapter. Chapter 2 on Numbers and Sequences is one of the highest-weightage chapters, covering arithmetic progressions, geometric progressions, and series. Key questions include finding the nth term, sum of first n terms, Euclid's division algorithm, and modular arithmetic. This chapter alone can carry 10 to 12 marks in the public examination.
Chapter 3 — Algebra
Algebra is consistently the most important chapter in 10th Mathematics, often carrying 15 to 20 marks. Key topics include simultaneous linear equations, GCD and LCM of polynomials, quadratic equations, and graphing. Practice solving quadratic equations by factorization, completing the square, and using the quadratic formula. Word problems based on quadratic equations are frequently asked in 5-mark questions. Students who master this single chapter secure a significant advantage in the examination.
Chapters 4 and 5 — Geometry and Coordinate Geometry
Geometry questions test both theoretical understanding and practical application. Important topics include similar triangles, Thales theorem and its converse, Pythagoras theorem, and tangent properties of circles. Always draw clear, labelled diagrams for full marks. Proof-based questions from this chapter are regularly asked as 5-mark questions. Coordinate Geometry covers the distance formula, section formula, area of a triangle, slope of a line, and equations of straight lines. These are straightforward scoring opportunities when you know the formulas and apply them with clear step-by-step calculation.
Chapters 6, 7, and 8 — Trigonometry, Mensuration, Statistics and Probability
Trigonometric identities and heights-and-distances problems are must-practice areas from Chapter 6, typically carrying 10 to 12 marks. Mensuration questions on surface area and volume of combined solids appear regularly as 5-mark problems in Chapter 7 — practice cylinder, cone, sphere, and hemisphere combinations thoroughly. Statistics and Probability from Chapter 8 include mean, median, mode calculations and basic probability problems that offer easy marks when practised well. Together these chapters contribute roughly 25 to 30 marks to the total paper.
How to Use This Chapter-Wise Approach Effectively
After identifying important questions from each chapter, solve them repeatedly until the method becomes automatic. First attempt each question without looking at the solution, then compare your answer with the model solution. Mark questions you found difficult and revisit them during revision. This targeted approach is far more efficient than reading the entire textbook cover to cover, and it ensures you are prepared for every section of the examination paper.
