Place Value - Multiplying and Dividing by 10, 100 and 1000

The whole school is having a big focus on Place Value. What Is Place Value in Maths? Place Value is the basis of our entire number system. This is the system in which the position of a digit in a number determines its value.

As part of our Place Value focus, we are learning about multiplying and dividing by 10, 100 and 1000.

Using Place Value Charts

We have been using Place Value charts to help us to divide by 10, 100 and 1000. This helps us to see how the digits change in value.

A trick to help us to remember how many places the digits need to move is by looking at the zeros in 10, 100 and 1000.

For example, there are 3 zeros in 1000, so we need to move the digits 3 places to the right to divide by 1000.

x10 - 1 zero move 1 place
x100 - 2 zeros move 2 places
x1000 - 3 zeros move 3 places

Example 723 ÷ 10
