Online Math CBSE and Olympiad Classes Syllabus for Grade 9

Olympiads are the stepping stones to achieve better results in the competitive world that lies ahead in the life of the child. Math Olympiad examinations help students to improve their mathematical skills along with their analytical and problem solving abilities. Along with that CBSE syllabus also plays a crucial role in the same.

Hence, Olympiad Success Live has designed a long-term course for Mathematics preparation which includes both CBSE syllabus and Olympiad for class 9. This long-term course will help in building the foundation of the child. For this, we have done great efforts in finding the tutor for class 9 Math CBSE and Olympiad preparation with relevant background and experience.

The curriculum of grade 9 CBSE Mathematics aims at enhancing the capacity of students to employ Mathematics in solving day-to-day life problems. It also inculcates interest in the students to study the grade 9 Maths subject as a separate discipline.

The students of grade 9, after the completion of this course,

  • acquire the ability to solve problems using algebraic methods
  • apply the knowledge of simple trigonometry to solve problems of height and distances
  • carry out experiments with numbers and forms of geometry, framing hypothesis and verifying these with further observations

The proposed curriculum for grade 9 CBSE can be checked below. For Olympiads preparation, you can check the syllabus here!

The objectives of the grade 9 Maths CBSE course is to help students to : 

  • consolidate the Mathematical knowledge and skills acquired at the upper primary stage
  • acquire knowledge and understanding, particularly by way of motivation and visualization, of basic concepts, terms, principles and symbols and underlying processes and skills
  • develop mastery of basic algebraic skills
  • develop drawing skills
  • feel the flow of reason while proving a result or solving a problem
  • apply the knowledge and skills acquired to solve problems and wherever possible, by more than one method
  • develop the ability to think, analyze and articulate logically
  • develop an awareness of the need for national integration, protection of the environment, observance of small family norms, removal of social barriers, elimination of gender biases
  • develop necessary skills to work with modern technological devices and mathematical software
  • develop an interest in mathematics as a problem-solving tool in various fields for its beautiful structures and patterns, etc.
  • develop reverence and respect towards great Mathematicians for their contributions to the field of Mathematics
  • develop interest in the subject by participating in related competitions
  • acquaint students with different aspects of Mathematics used in daily life
  • develop an interest in students to study Mathematics as a discipline

We understand that the teaching of Mathematics should be imparted through activities that may involve the use of concrete materials, models, patterns, charts, pictures, posters, games, puzzles and experiments. Hence, keeping in mind the curricular expectations, Olympiad Success Live has designed a course for CBSE Maths preparation for class 9 students. And for this, we have the right set of tutors with relevant backgrounds and experience for class 9 Maths CBSE preparation.
