If you are a Class 9 student or a parent who wants to learn about the CBSE Class 9 Maths syllabus 2025-26, then this blog is for you. The blog refers to various content, including deleted topics and key chapters, as well as a study plan for revision, all in a student-friendly way.
What's New in 2025-26 Maths Syllabus?
CBSE has made some minor changes to the Class 9 Maths syllabus in view of the recommendations from the NEP and changes in the student centric assessment. Although the purpose and rhythm will remain the same, a number of topics were left out or rationalised to ease the load on students as well as to instill learning that is more meaningful.
An important update is that none of the chapters have been eliminated as such, but some of the subtopics have been omitted especially those regarding Construction, linear equations and some of the applications of Heron’s Formula.
Topics Deleted This Year (2025-26)
Following the changes, it is also important to note deleted topics as well. Here are the topics that CBSE has removed this year:
• Construction of certain angles using just a compass
• Graphical Solution of Simultaneous Linear Equations.
• A few complex applications of Heron’s Formula in non-right triangles.
If you still didn't receive books in your class 9 that include these topics, I suggest ticking the topics off as "not in syllabus" and from here on, you can save some precious time.
