## Expand Students’ Understanding of Expanded Notation

Whether you call it expanded notation or expanded form, learning to represent numbers by breaking them down is a key element of place value instruction. So how do students remember the value of each digit? Classroom posters to the rescue!

The math teachers on the Teach Starter team created this simple visual reference tool to hang up in your classroom.  Available in an easy-to-print PDF format, the poster is available in full color.

## What Is Expanded Notation? A Kid-Friendly Definition

Do you need a kid-friendly definition to introduce expanded notation to your class? Here’s the one you’ll find right on the poster:

Expanded notation is writing a number to show the value of each digit. It represents a number as the sum of each of its digits multiplied by their place value (ones, tens, hundreds, etc.)

For example:

384 = 3 x 100 + 8 x 10 + 4 x 1
= 300 + 80 + 4
= 384
