Number names are a way of expressing the written form of numbers using letters. Learning number names will help you learn the basics of counting, addressing parcels, official documents, and so on. In this topic, we will learn number names from 1 to 15.
These are the words that we use to represent numbers, which makes it easier to read. Take the number 5; it is written as ‘Five’. Writing numbers in words not only helps us write legal documents and fill forms, but it also helps improve a student's spelling skills.
There are two different ways of naming numbers: the Indian Numbering System and the International Numbering System. You need to understand how numbers are named using both numbering systems. This will help you in communication as well as in arithmetic calculations.
Now, let’s discuss the two numbering systems.
In the Indian Numbering System, digits are assigned place values starting from the right. These place values include ones, tens, hundreds, and thousands, and continue to grow as the number increases.
For numbers like 15, the digit 5 is in the ones place, and 1 is in the tens place. Starting from the right, the order goes from ones to tens, hundreds, thousands, ten thousands, lakhs, ten lakhs, and crores. Each digit has its value based on its position in the number.
Let’s take an example of the number 1,23,456. The number is written as One Lakh Twenty-Three Thousand Four Hundred Fifty-Six.
The number is placed as:
1 in the lakhs place
2 in the ten thousands place
3 in the thousands place
4 in the hundreds place
5 in the tens place
6 in the ones place
Just like the Indian Numbering System, the International Numbering System also uses names, and they differ for bigger numbers.
The place value starts from the right. The place values are ones, tens, hundreds, thousands, hundred thousands, millions, ten millions, hundred millions, and so on.
Let’s take the example of 123,456. The number is written as One Hundred Twenty-Three Thousand Four Hundred Fifty-Six.
The number gets placed as:
1 in the Hundred Thousands place
2 in the Ten Thousands place
3 in the Thousands place
4 in the Hundreds place
5 in the Tens place
6 in the Ones place
Learning the names of the numbers from 1 to 15 using a chart will make it easy for the students to write the numbers in words. List of Numbers in Words 1 to 15 The list given below shows how numbers from 1 to 15 are written using letters. Learning to write the numbers in words improves their skills in reading and writing.
While writing numbers from 1 to 15, there are certain rules to be followed. Below discussed are some rules to keep in mind while writing the names of numbers.
Rule 1: Always start with the number name for 1 as 'One'. For example, 1 is written as One.
Rule 2: The numbers follow a pattern. For example, 11 is written as Eleven, 12 is written as Twelve, and 13 is written as Thirteen.
Focus on special number names like Eleven, Twelve, and Thirteen, as they do not follow the regular naming pattern. Practice regularly to remember the names of numbers from 1 to 15, as these are foundational for learning larger numbers. Use rhymes or songs to make memorization easier for young learners.
Students can make mistakes while learning number names. Let’s discuss a few mistakes a student can make while writing numbers from 1 to 15.
