CBSE Class 9 Maths Deleted Syllabus 2022-23: Download in PDF

Responding to evolving learning needs and building on the previous year’s adjustments, the CBSE has further streamlined the Class 9 Maths syllabus for the academic year 2024-25. This revision aims to prioritize core concepts while easing the burden on students and teachers.

  • Geometry: While retaining core aspects, the syllabus moves beyond specific theorems and proofs like those related to similarity of triangles (Proportionality, Thales, Pythagoras). This allows for deeper exploration of fundamental geometric principles relevant to various shapes and constructions.
  • Algebra: Similar to geometry, the focus shifts from verifying and proving identities to understanding the underlying algebraic concepts. Students will still gain proficiency in manipulating expressions and equations, but with a more practical approach.
  • Mensuration: Formulae for surface areas and volumes of complex 3D shapes like cones, cylinders, spheres, and frustums are no longer part of the curriculum. Instead, emphasis is placed on applying mensuration principles to solve real-world problems involving simpler shapes.
  • Number Systems and Statistics: Validation of irrational numbers like √2, √3, √5 is removed. Descriptive statistics concepts like calculating mean, median, and mode for grouped data are also streamlined, focusing on core understanding rather than specific calculations.
  • Other Streamlined Topics: Constructions like trisection of lines and angles, areas related to circles, and coordinate geometry are also adjusted, with the focus shifting towards practical applications and problem-solving skills.
  • Learning Outcomes: The revised syllabus aims to improve learning outcomes by focusing on deeper understanding and application of core mathematical concepts.
  • Teacher Adaptation: Teachers are encouraged to adapt their classroom strategies to ensure students grasp the key concepts while bridging any potential learning gaps caused by the streamlined content.
  • Higher Classes: While some experts express concerns about the long-term impact of dropping certain topics on students’ preparedness for higher classes, the CBSE maintains that the revised syllabus equips students with a strong foundation for further learning.

The official detailed syllabus document for Class 9 Maths (2024-25) is expected to be released soon by the CBSE. Schools and teachers are advised to refer to the official document for specific details and adapt their teaching approaches accordingly.

By optimizing the curriculum and focusing on core concepts, the revised CBSE Class 9 Maths syllabus seeks to equip students with a strong foundation for higher-level mathematics while making the learning process more engaging and relevant.

Please note: This revised article reflects potential changes for the 2024-25 academic year based on the previous year’s adjustments and current trends. Always refer to the official CBSE resources for the latest and accurate information.
