 ## 7th Standard Maths CBSE Updated Chapters & Syllabus 2020-2021

Building a strong base in mathematics in the middle-school is very important for mathematics students. 7th standard maths holds crucial importance in shaping and developing the minds of the students for higher studies. Class 7 maths comprises some new topics that students are introduced for the very first time. These topics form the base for higher mathematical studies during high school as well as in professional courses.

Maths often seem to be a tricky and challenging subject to some students in the board exams. The main reason behind this is that students are not well familiar or very thorough with the junior and mid-school maths and foundation topics taught in middle school. Class 7 maths hence hold prime importance in preparing students for even board exams. If a student gets well versed with all the chapters and topics included in the 7th class maths syllabus, and later classes, they will not find it difficult to crack the board exams.

The teachers and the subject matter experts at the CBSE have designed the 7th grade maths syllabus with utmost attention to multiple areas of mathematics. It includes geometry, algebra, integers, data handling, probability, angles, and so on.

We can say that the ncert 7th class book is a combination of all the mathematics topics studied till class 6 with further elaboration and some additional issues. If a student is thorough with his or her syllabus till grade 6, they will easily be able to understand and learn ‘class 7 maths’. Here we have a quick but detailed view of the class 7th maths syllabus.
