Converting numbers from their conventional form into written and expanded forms is one way to start understanding place value. That nine digit in the hundreds place is something much different from a nine digit in the ones place, and these concepts are sometimes difficult to pickup. The worksheets on this page practice converting numbers between standard, expanded and word form to help build these concepts, and include worksheets with special edge cases that often trip up grade school students just staritng to explore place value.

Converting Numbers Between Forms
When we write numbers in standard numeric form, we make many assumptions that young grade school students need to learn explicitly. A good example is when we speak a number outload (in 'word form'), we skip over place values that have zeroes in them. This subtle discontinuity is something that can easily confuse students still struggling with place value, and you may see numbers like 'four thousand six' written as '46' as an answer. Whoops!
The printable worksheets on this page practice converting numbers to both expanded form and word form. This helps students focus on the place values of individual digits as well as increase understanding of how we pronouce numbers. The worksheets have problems of varying length (more digits!) convert different directions. Each different type of number conversion worksheetand when you might want to apply it is discuss in more detail below.
Using the Expanded Form Worksheets
The worksheets on this page require the student to write numbers in expanded form, writing numbers in standard form and rewriting numbers in word form. Numbers themselves have a specific meaning, which is the exact count of the objects to which the number refers. There are several means of expressing a number, and each has a different role to play. However, when starting to understand place value, being able to convert numbers to expanded form or back is a very useful skill.
The expanded form worksheets on this page are great practice for students learning about place value and a larger digit numbers.
What is Expanded Form?
Expanded form is a way to write a number such that all of the place value components of the number are separated.
When we write a number in expanded form, each digit is broken out and multiplied by its place value, such that the sum of all of the values equals the original number.
Writing Numbers in Expanded Form
The easiest way to visualize writing a number in expanded form is to see an example. Consider the number 1234. This number has three digits, so the expanded form representation of the number will have three components.
1,234 = 1000 + 200 + 30 + 4
When the number is written in expanded form, it is easier to understand the exact magnitude of each digit. In this example, even though the '1' in the thousands place is numerically smaller than the '4' in the ones place, the expanded form notation makes it clear that the place value connotes a much larger value even though the digit itself is smaller.
Numbers in Word Form
Numbers in word form are written in a way that corresponds to how you would read the value of a word aloud. For smaller numbers, number word form is something most students have a familiarity with and it's easy to grasp..
123 in word form is 'one hundred twenty three'
The complexity comes when periods (we're not talking about decimals here) are introduced. A period in numerical form is a group of three digits denoting the major place values of groups of the numbers. These are typically the thousands, millions, billions and similar amounts that are separated into groups of three place values either by decimals (or, in some countries, by commas). So for example, consider this number..
123,123,123
The word form of this number is 'one hundred twenty three million, one hundred twenty three thousand, one hundred twenty three.' You'll notice that the typical grouping of numbers corresponds to where we introduce the words 'millions' and similar. The goal of the word form worksheets here is to develop a level of comfort with these period groupings.
Note that when you write numbers in word form (or speak numbers for that matter), that the use of the word 'and' is a very specific indicator of that the whole component of the number in question has been completely described and that the decimal place starts. So for example..
4,321.5 = 'four thousand, three hundred twenty one and five tenths.'
The word 'and' here tells us where the decimal place occurs and where we're about to start a word form description of the fractional or decimal component of the number. This is important not just in writing numbers in word form, but also when writing the numerical description of a dollar amount while writing a check or other legal description of money. There the part after the 'and' is usually described as cents.
Either way, don't make the mistake of using the word 'and' anywhere while writing the word form of the wholes!
Teaching Place Value with Expanded Form Worksheets
Expanded form worksheets reinforce place value concepts by getting students to consider the actual value assigned to each digit in a number. Even though the process seems simplistic, by practicing converting to and from expanded form, your pupils develop a more innate number sense by being forced to consider not just the absolute value of a digit, but it's correspondence to its position in the entire number.
A good place to start is either the earlier worksheets in the Place Value Expanded Form Worksheets or the Conventional Expanded Form Worksheets and then gradually work through these, incorporating expanded form exercises with decimals if you have convered those topics.
Write 2.685 In Expanded Form
Decomposing numbers into expanded form is somewhat more procedural than going to other forms, but once this skill is mastered any of the reverse Numbers From Expanded Form Worksheets will reinforce the concepts.
You can choose to vary the complexity of the work you assign by selecting expanded form worksheets with longer digits or with decimal values, or simply mix these worksheets in as review assignments periodically, especially with students who seem to struggle with basic operations involved multi-digit problems.
Regardless of what approach you choose, all of the worksheets on this page, including the expanded form worksheets, will provide help converting between different forms of numbers and teaching place value. Also be sure to check out the place value chart for help figuring out periods and other subtleties of place value!

This translator converts numbers into words (or numbers to letters, if that makes more sense). Write '1' in the box on the left, and 'one' will appear on the right. It converts very large numbers into their word form - see if you can find the biggest! (Hint: You'll need more than 1000 digits!!) I'm pretty sure this translator is the best numbers to words converter on the whole internet in terms of being able to convert craaazzy large numbers into words form. I didn't really have any particular use case in mind when I made this generator, but hopefully you have some need for numbers in words format, and can use this to help solve your problem :)
Many people will likely know the number 'googol' (after which the famous tech company 'Google' is named) - it's the digit '1' with one hundred zeros after it - a number which is dozens of orders of magnitude greater than the number of atoms in the visible universe. It's ridiculously big. But who would have know that the named numbers go hundreds or orders of magnitude higher than this?! If you can find the highest named number by typing digits in the box, post it in the comments!
It's worth noting that there are often a few different possible names which can be used for the same number. For example, a googol can also be called ten duotrigintillion, ten thousand sexdecillion, or ten sexdecilliard. Since these numbers are very rarely used, there is not standard or governing body and so it's a bit of a wild west. In trying to create a useful numbers ot words translator I figured I'd just try to translate each number into the most commonly used name, and one that is consistent with the rest of the number names.
To slightly complicate the issue further, there are multiple possible spellings of the same name. So for example, we can spell the aforementioned number as duotrigintillion or dotrigintillion. Number names, and number spelling are fairly consistent for the first few dozen orders of magnitude after the number one, but after that, they begin to diverge.

It's interesting that standard 'dictionary' words for very large numbers didn't appear in English until around the 1400s. The words bymillion and trimillion appeared for the first time in a 1475 manuscript of Jehan Adam.Some languages have a very small emphasis on numbers. For example, the Pirahã people are thought to have no numbers in their language at all. They appear to only have words for 'more' and 'few'. They also have no grammatical distiction between singular and plural - for example, the word for 'people' is the same as the word for 'person'.
All thanks to Flambino for providing the script that runs this translator! I also had to use big.js by @MikeMcl, since the numbers are far too big for javascript to handle with it's built-in types. It turns out that (when you want to get the names of big numbers), writing working code to translate numbers into words isn't the easiest of tasks! Huge thanks to these two guys for making my life a tonne easier.
If you've got any suggestions, or if there's any errors in the word-form of the numbers, please let me know! Textsoap v8 0 8 download free. Thanks :)
