In third grade, you learned how to write numbers in words up to 1,000.
In this lesson, we're going to learn to write numbers in words up to millions!
When writing numbers in words, you write out place value words to show the value of each digit.
Pause and memorize this chart:
Numbers under 100 are so common, they're written as just one word, like forty, or with a hyphen -, like twenty-one.
How do we write even larger numbers?
Let's learn with some examples.
What's 3,628 in words?
Start by writing the word for the leftmost digit 👈. This is the digit with the largest place value, 3.
Write "Three thousand".
The next three digits are 628. In words, that's "six hundred twenty-eight".
Put these together:
Three thousand six hundred twenty-eight ✅
Tip: Don't write commas when writing numbers.
Fantastic! 👏
Let's do it together.
Write 389,456,712 in words.
First, divide the number into groups of 3.
Tip: Commas tell you how to divide the digits.
Start with the biggest group, the millions group.
1️⃣ Write the group 389 in words as three hundred eighty-nine.
Then, add the word "million" at the end.
Three hundred eighty-nine million
Tip: Put a hyphen - between eighty and nine. It's like the Ones and Tens digits within each group of three gets a hyphen.
Do the same with the thousands group.
2️⃣ 456 in words is four hundred fifty-six.
Then, add "thousand" at the end.
Four hundred fifty-six thousand
The last group is made up of the digits in the Hundreds, Tens, and Ones.
3️⃣ 712 in words is seven hundred twelve.
Finally, we put all these words together.
Three hundred eighty-nine million four hundred fifty-six thousand seven hundred twelve
Tip: We don't add an "and" anywhere.
Great job! 🎊
How do you write 19,806,320 in words?
First, group the digits.
Then, write the value of each group in words.
Finally, put all the words together!
Nineteen million eight hundred six thousand three hundred twenty
