Each of the following examples shows the same number written a different way.

  • sixty-six thousand, seven hundred twenty-one, and forty-four thousandths
  • 60,000 + 6.000 + 700 + 20 + 1 + 0.04 + 0.004
  • 66,721.044

Which example shows the number in written form? Read on to find out why it's important!

If you said the first example is shown in written form, you are correct!

In the previous Related Lesson, found in the right-hand sidebar, you learned about numbers written in standard form. Tell your teacher or parent which example is written in standard form.

The third example is written in standard form, which is how you will see numbers written most often.

In this lesson, you will learn how to read, write, and compare numbers in written form. Written form is exactly what it sounds like: it is the number spelled out using words. Look at each of the examples below. The left column shows the number written in standard form, and the right column shows the same number written in written form. Tell your teacher or parent what you observe as you look at each example:

6,821,003.4 six million, eight hundred twenty-one thousand, three, and four tenths
527,891.261 five hundred twenty-seven thousand, eight hundred ninety-one, and two hundred sixty-one thousandths
1,635,489.654 one million, six hundred thirty-five thousand, four hundred eighty-nine, and six hundred fifty-four thousandths


A few things you should have noticed when examining each of the numbers shown in written form:

  • Like numbers written in standard form, the whole numbers are grouped into sets of three numbers. These groupings, also known as periods, are separated with commas. When reading a number, the comma represents a pause.
  • The decimal is represented by the word "and."
  • Place values behind the decimal always end in "–th," like four tenths.
  • A hyphen (-) should be used between numbers that end in "–ty." For example, thirty-five, fifty-four, eighty-nine, etc.

Now that you have looked at examples of numbers in written form, move on to the Got It? section to practice writing numbers in written form.
