Build strong number sense with the five most important early maths concepts — counting objects, writing numbers, number names, even and odd numbers, understanding number order, and skip counting. These topics form the foundation of the Number System taught in Class 1 and Class 2 under CBSE and UP Board mathematics.

What Students Learn in Counting & Number Names
The topics in this section introduce students to the basic ideas that form the foundation of the number system. Children first learn how to count objects and write numbers correctly. Once they understand numbers as quantities, they move on to recognising number names, identifying even and odd numbers, and understanding the order of numbers.
Students also practise identifying which number comes before, after or between two given numbers. These exercises strengthen number sequence understanding. Another important skill introduced at this stage is skip counting, where students count numbers by 2s, 5s, 10s or 100s. This skill later becomes the base for multiplication tables and mental maths.
Class 1 — Building Early Number Sense
In Class 1, students begin by counting real objects around them such as pencils, toys or books. They learn to write numbers correctly and understand that each number represents a specific quantity. At this stage, children also learn to identify even and odd numbers and practise exercises related to number order such as finding numbers that come before, after or between others.
Class 2 — Extending Number Skills
In Class 2, students extend these ideas further by reading and writing larger numbers and learning number names. They also practise skip counting by different numbers which helps them recognise patterns within the number system. These activities develop stronger mental maths skills and prepare students for more advanced arithmetic concepts in later classes.
