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
