Number names are a way of expressing numbers in their written form using letters. Learning number names will aid in mastering the basics of counting, addressing parcels, filling out official documents, and more. In this topic, we will learn number names from 100 to 1000.
Number names are words used to represent numbers, making them easier to read and write.
For example, the number 250 is written as ‘Two Hundred Fifty’.
Writing numbers in words not only helps with legal documents and form-filling, but also improves a student's spelling and number sense.
There are two different ways of naming numbers:
The Indian Numbering System
The International Numbering System
Understanding both systems will help with better communication and more accurate arithmetic calculations.
Let’s now explore these two numbering systems.
In the Indian Numbering System, digits are given place values starting from the right.
These include: ones, tens, hundreds, thousands, and the values grow as the number increases.
For example, in the number 786:
6 is in the ones place
8 is in the tens place
7 is in the hundreds place
The full order of place values is:
Ones → Tens → Hundreds → Thousands → Ten Thousands → Lakhs → Ten Lakhs → Crores
Let’s take the example of 12,34,567
This number is written as:
Twelve Lakh Thirty-Four Thousand Five Hundred Sixty-Seven
Now let’s place the digits:
1 in the ten lakhs place
2 in the lakhs place
3 in the ten thousands place
4 in the thousands place
5 in the hundreds place
6 in the tens place
7 in the ones place
In the International Numbering System, place values also start from the right.
The order of place values is:
Ones → Tens → Hundreds → Thousands → Ten Thousands → Hundred Thousands → Millions → Ten Millions → Hundred Millions, and so on.
Let’s take the example of 456,789,123
This number is written as:
Four Hundred Fifty-Six Million Seven Hundred Eighty-Nine Thousand One Hundred Twenty-Three
Now let’s place the digits:
4 in the Hundred Million place
5 in the Ten Million place
6 in the Million place
7 in the Hundred Thousand place
8 in the Ten Thousand place
9 in the Thousand place
1 in the Hundreds place
2 in the Tens place
3 in the Ones place
Learning the names of numbers from 100 to 1000 using a chart helps students easily convert numbers to words. List of Numbers in Words 100 to 1000 Below is a list showing how numbers from 100 to 1000 are written in words. Learning to write numbers in words enhances reading and writing skills.
While writing numbers from 100 to 1000, follow these rules: Rule 1: Numbers from 100 to 199 start with ‘One Hundred’. For instance, 150 is written as One Hundred Fifty. Rule 2: For numbers starting with 200, use “Two Hundred”. For example, 201 is written as “Two Hundred One.” Rule 3: Numbers after 100 follow a pattern. For example, 245 is written as Two Hundred Forty-Five, 368 is written as Three Hundred Sixty-Eight, and 472 as Four Hundred Seventy-Two.
- Always use a hyphen while writing numbers like 245 and 678. They should be written as Two Hundred Forty-Five and Six Hundred Seventy-Eight. - Always include ‘Hundred’ in numbers like 100, 200, up to 900. - For numbers like 110, 220, 330, focus on the tens place. After writing One Hundred, Two Hundred, etc., add the number. For example, One Hundred Ten, Two Hundred Twenty, and Three Hundred Thirty.
