Lesson 2: Writing whole numbers in expanded form

# Whole numbers in expanded form review

Review writing whole numbers in expanded form, and try some practice problems.

## Expanded form

Expanded form is a way to write a number by adding the value of its digits.
We can use a place value chart to think of the value of a number's digits.

### Example

Let's write $7229$ in expanded form.
ThousandsHundredsTensOnes
$7$$2$$2$$9$
$\phantom{7229}=7000+200+20+9$
$7229$ in expanded form is $7000+200+20+9$.
