You can write numbers in different forms. Expanded form means writing the number so you show the value of each digit. Word form means writing the number with words instead of numerals.

LET’S BREAK IT DOWN!
Review Place Value.
Place value is the value of a digit based on its position in a number. 246 is 2 hundreds, 4 tens, and 6 ones.
Write Numbers in Expanded Form.
Expanded form is a way to write a number that shows the value of each digit. In 425, the value of 4 is 400. The value of 2 is 20. The value of 5 is 5. In expanded form, 425 is 400 + 20 + 5.
Write Numbers in Word Form.
You can also write numbers with words. Word form represents how you say a word when you read it out loud. In word form, 642 is “six hundred forty-two.” 214 is “two hundred fourteen.”
Write Expanded Form with Zeroes.
Sometimes numbers have a 0 in them. 305 is 3 hundreds, 0 tens, and 5 ones. 305 in expanded form is 300 + 5. The expanded form doesn't show tens as there are 0 tens. 450 is 4 hundreds, 5 tens, and 0 ones, or 400 + 50.
Reading Numbers with Zeroes.
There are no tens in 305. When reading 305, you say "three hundred five". There are no ones in 450. When reading 450, you say "four hundred fifty."
