## IMO Class 2 Chapter 4: Comparing Numbers Detailed Notes

Numbers are represented as a group of numbers that the class 2 child can manipulate. These numbers are extremely useful in determining the numerical value of any object at any stage of life.

For example, suppose you want to buy two chocolates; “two” specifies the exact number of chocolates you want to purchase. This is where your number sense comes in handy.

You will find numbers everywhere you go, but keep in mind that each number has a unique value. Assume you own two cars, two notebooks, and two toys.

All of the objects, in this case, are distinct, but they all have the same numerical value. Furthermore, you will notice that these numbers are written in symbols, such as 1,2,3,4, and so on.

These numbers are critical, especially for Class 2 students, in helping them understand the Number Sense concept.

Comparing numbers is a fundamental concept that we learned in elementary school. When we need to compare two numbers or quantities, we use three basic symbols:

• equals (=)
• greater than (>) symbol
• The symbol for less than (<)

In this article, we will learn how to compare two numbers and which sign should be used to do so.

Less than, more than, or equal to

Less than (), greater than (>), and equal to (=) are the three comparison symbols.

The “equal to” symbol is used to represent two numbers or quantities that are equal, such as:

3 = 3 or 10 – 7 = 3

The “greater than” symbol indicates whether one number is greater than another. As an example,

10 > 3 [10 is greater than three]

When one number or quantity is less than another, the “less than” symbol is used. As an example,

9 < 11 [nine is less than eleven]

Use of the terms less than and greater than

The less than and greater than symbols are used to compare two numbers.

A greater number than a lesser number is represented as:

Greater Number > Lesser Number

A smaller number less than a larger number is written as:

Smaller Number < Greater Number

Number Comparison Rules

There are certain rules that make it easier to compare numbers. These are the rules:

• Numbers with multiple digits.
• Numbers that begin with a higher digit
