Expanded Notation Poster

1 page|Grades: 3 - 7

A poster explaining expanded notation.

Information on poster includes:

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

Expanded notation can also be used when working with powers of 10.

100 = 10 x 10

1 000 = 10 x 10 x 10.

I would like to see a poster that shows the difference between expanded form (2 x 100 + 3 x 10 + 4 x1) and expanded notation (200 + 30 + 4) – thanks.
