Explore the world of expanded notation with a printable classroom poster that easily explains the concept for children!
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 pupils remember the value of each digit? Classroom posters to the rescue!
The maths teachers on the Teach Starter team have created this simple visual reference tool to hang up in your classroom. Available in an easy-to-print PDF or editable Google Slides format, the poster is available in full colour and black and white.
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
