What Is Expanded Form?

Expanded form is a term that describes writing a number according to the value of its digits. You can think of the math concept this way: If you have the number 435, it would be written in expanded form as 400 + 30 + 5. That means there are 4 hundreds, three tens, and 5 ones in this (expanded) number. Teaching expanded form is a way to help students get familiar with place value. So it's probably no surprise to you that one must-have teacher tool for teaching this way to write numbers is a place value chart! It helps students to get familiar with the value of a number's digits.

Teaching Expanded Form

Expanded form activities are often pulled out in the first few weeks of the school year, but you might consider adding these to your math centers all year for a few reasons!
  • It helps younger math students understand the value of zeros in those longer three- and four-digit numbers.
  • It helps students understand how the digits 0, 1, and 2 form multi-digit numbers
