Telangana Board class 7 Mathematics Syllabus

Mathematics is merely not only a subject of study. In today’s world, it becomes a language for communication and thought process. It is a rudimentary subject for the development of scientific knowledge and technological importance. Mathematics is the nucleus for all the subjects.

The Board of Secondary Education,Telangana formulated the syllabus in such a way to provide a sound knowledge on mathematics. The main objectives are:

  • Developing mathematical way of thinking
  • Application of mathematics in our real life situation
  • Developing a positive attitude towards a study of mathematics.

Here is the mathematics  syllabus for class 7 Telangana Board:
