Number Words – Definition with Examples
Updated on September 29, 2026
Number words, often termed as number names, are fundamental components of mathematical understanding and communication. The essence of number words transcends the mere depiction of numerical values. Instead, they are a symbolic embodiment of mathematical quantities, aiding in comprehension and quantitative reasoning. For example, ‘three’, ‘eighteen’, ‘twenty-seven’ are number words that correspond to the numerical figures 3, 18, and 27.
At Brighterly, we believe that grasping number words is akin to unlocking a gateway into the world of numeracy for young learners. Number words intertwine the spheres of language and mathematics, enabling children to articulate quantities, perform counting exercises, appreciate number sequences, and eventually, understand complex mathematical operations. Therefore, in the initial stages of mathematical education, a primary focus is on enabling children to connect numerical values with their corresponding number words. This involves interactive and engaging learning approaches, such as colorful number-word matching games, songs that incorporate number words, and intriguing story problems featuring number words.
What Are Number Words?
Number words, also known as number names, form a vital part of our everyday communication. They’re the verbal or written representation of numerical values. For instance, ‘one’, ‘two’, ‘three’, are the number words for 1, 2, 3 respectively. Their role is undeniable in our daily lives, be it counting, measuring, or ordering items. They are especially crucial in the world of mathematics, particularly in early childhood education, where they serve as an essential tool for learning and understanding basic math concepts. Emphasizing the importance of number words, the Brighterly asserts that developing a clear understanding of these words lays a solid foundation for mathematical literacy.

Rules to Write Numbers in Word Form
Converting numbers into word form follows certain rules. For numbers from zero to ten, we simply write them out: zero, one, two, three, and so forth. For numbers between 11 and 19, we use specific terms like eleven, twelve, thirteen, up to nineteen. The decade numbers, 20 to 90, end in “-ty” such as twenty, thirty, forty, and so on. For other two-digit numbers, we use a hyphen between the decade and the unit place, like twenty-one, thirty-five, etc. Beyond 99, the structure becomes more complex with the introduction of hundreds, thousands, and higher units, but the basic principles remain the same. These rules, detailed on Brighterly, are key in writing number words correctly.
Number Words or Number Names from 1 to 100
Learning number words from 1 to 100 is an essential step for children as they begin their math learning journey. It starts with understanding simple numbers such as ‘one’, ‘two’, ‘three’, etc., then progresses to more complex forms like ‘eleven’, ‘twenty-two’, ‘thirty-three’ and so on. Each of these number words has a unique name that corresponds to its numerical value. There are plenty of resources available, like this comprehensive list that provides the number words from 1 to 100, which can aid in familiarizing children with these words.
The Number Words for Higher Values
For numbers beyond 100, we have to consider higher values such as hundreds, thousands, millions, billions, and so on. For instance, the number 1234 would be written as ‘one thousand two hundred thirty-four’. The same pattern applies to larger numbers, where each group of three digits from right to left represents hundreds, thousands, millions, etc. A comprehensive guide on writing large numbers in words can be found on Brighterly.
Number Names as per the International Number System
The International Number System is widely used across the globe. In this system, each group of three digits separated by commas is given a specific name. For instance, 1,000 is called ‘one thousand’, 1,000,000 is ‘one million’, 1,000,000,000 is ‘one billion’, and so on. More details can be found on educational sites like the Brighterly.
Place Value Chart for International System
A place value chart is a useful tool to understand the International Number System. The chart typically starts with ones (units), tens, hundreds, then it jumps to thousands, ten thousands, hundred thousands, millions, and so forth. Each place represents a power of ten, which is a fundamental concept in understanding number words in this system. An example of this chart can be seen on the Brighterly website.
How to Write Popular Numbers in Words
The rules above cover every number, but it helps to see them applied. The tables below show the numbers people look up most often, from small two-digit numbers to millions. Find your number in the left column and read its word form on the right.
A few things to keep in mind as you read:
- Hyphenate numbers from 21 to 99 when they have two parts: thirty-six, forty-nine, seventy-two.
- Say the thousands group, then the rest. For 14,500 you read “fourteen thousand,” then “five hundred.”
- Commas stay out of the words. 120,000 is written “one hundred twenty thousand,” with no comma.
- “And” is optional. American English usually leaves it out (one hundred five thousand). British English often adds it (one hundred and five thousand). Both are correct.

Patterns Worth Noticing
Once you look at the tables side by side, a few shortcuts show up. Numbers like 12,500 or 18,500 are read as the thousands part plus “five hundred.” Round numbers in the hundreds of thousands, such as 300,000 or 700,000, are just a single digit followed by “hundred thousand.” And in the millions, 1,500,000 is the same as “one and a half million” in everyday speech, although the full form is safer on checks and official documents.
