## NCERT Textbook & Solution

Class 2 Mathematics NCERT textbook has 15 chapters.

Starting from shapes and space to counting numbers upto 50. Class 1 Maths is beautifully bifurcated into various chapters in which student actively learn by doing various activities under the guidance of a teacher.

Various activities are beautifully drawn and presented in such a manner that student feels connected with the activities. Whether solving exercise or filling or outlining the shapes and numbers, students are very much engaged in completing the various tasks allotted to them.

The detailed syllabus has been discussed below along with the Key Concepts and Learning outcomes. So that learning can be Joyful.

## Chapter 1

## What is Long, What is Round?

- Spatial relationship (position of the objects)
