Numbers: CBSE Class 1 Maths NCERT Guide

What Are Numbers and Why Do We Need Them?

Numbers are special symbols that tell us 'how many'. For example, if you see the symbol '3', it means you have three of something. It could be 3 pencils, 3 friends, or 3 cookies! Each number has its own name and its own look. The number '1' is called 'One', '2' is called 'Two', and so on. We need numbers every single day. They help us count our money, tell the time, measure how tall we are, and play games. Imagine trying to play hide-and-seek without counting! By learning numbers, you are learning a language that everyone in the world understands.
