Introduction
The reduced Class 10 Mathematics syllabus has been implemented to help students focus on essential concepts during challenging times. This document outlines the topics that have been deleted from the original syllabus, allowing both students and teachers to concentrate on the remaining areas more effectively.
Deleted Topics by Chapter

Deleted topics from Polynomials include:
- Relationship between zeros and coefficients
- Division algorithm for polynomials
Chapter 3: Pair of Linear Equations in Two Variables
The following topics have been deleted:
- Pair of linear equations in two variables graphical method of their solution
- Consistency/inconsistency

Chapter 6: Triangles
The following topics have been deleted:
- Proof of the following theorems are deleted: (i) 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. (ii) If a line divides two sides of a triangle in the same ratio, the line is parallel to the third side. (iii) The ratio of areas of two similar triangles is equal to the ratio of the squares of their corresponding sides.
Chapter 7: Coordinate Geometry

- Trigonometric ratios of complementary angles
Chapter 9: Some Applications of Trigonometry
This chapter remains unchanged with no deleted topics.
Chapter 10: Circles
Deleted topics include:
- Prove that lengths of tangents drawn from an external point to a circle are equal
Chapter 11: Constructions
The following topics have been deleted:
- Construction of a triangle similar to a given triangle
Chapter 12: Areas Related to Circles

Chapter 13: Surface Areas and Volumes
The following topics have been deleted:
- Frustum of a cone
- Problems involving converting one type of metallic solid into another and other mixed problems
Chapter 14: Statistics
Deleted topics from Statistics:
- Step deviation method for finding the mean
- Analysis of frequency distributions with equal means but different variances
Chapter 15: Probability
This chapter remains unchanged with no deleted topics.
Impact on Examination Pattern
The assessment pattern has been modified to align with the reduced syllabus. The question paper will now focus more on understanding concepts rather than rote learning. Internal assessment has gained more importance, with schools conducting periodic tests, multiple assessments, and portfolios to evaluate students' understanding of mathematical concepts.
Study Tips for Updated Syllabus
- Focus on understanding the core concepts rather than memorizing formulas
- Practice solving questions from previous years that align with the current syllabus
- Create a study plan that gives adequate time to each remaining topic
- Work on sample papers to get familiar with the modified exam pattern
- Focus on the chapters that carry higher weightage in examination
- Strengthen your basics in arithmetic and algebra, as they form the foundation for many concepts
- Practice solving problems regularly to improve speed and accuracy
Weightage Distribution
| Unit Name | Weightage |
|---|---|
| Number Systems | 06 |
| Algebra | 20 |
| Coordinate Geometry | 06 |
| Geometry | 15 |
| Trigonometry | 12 |
| Mensuration | 10 |
| Statistics and Probability | 11 |
| Total | 80 |
Note: The internal assessment will carry 20 marks, making the total assessment 100 marks. Students should pay equal attention to both theoretical and practical aspects of mathematics.
Recommended Textbooks and Resources
When preparing with the updated syllabus, it's crucial to use resources that reflect these changes:
- NCERT Mathematics textbook for Class 10
- NCERT Exemplar Problems
- Sample question papers released by the education board
- Online practice platforms with updated question banks
- Refresher guides specifically designed for the reduced syllabus
Conclusion
Understanding the deleted syllabus is essential for focused preparation. Students should avoid wasting time on topics that are no longer part of the examination. Instead, they should allocate their study hours to understand and practice the remaining topics thoroughly. The reduction in syllabus is an opportunity to gain deeper conceptual understanding rather than covering a vast amount of content superficially.
Teachers and parents play a crucial role in guiding students to adapt to these changes. Regular assessment and feedback will help students stay on track and achieve success in their mathematics examinations despite the challenges.
