Place value is really important when building up numbers. The order the digits are written in a number determine its value.

To remind you what place value is, here's an introduction with some dinosaur friends.

A number can be made of more than one digit. So we use place value headings, like ones, tens, hundreds and thousands, to help us understand the value of each digit.

Example 1

How do you represent the number 167 with a place value chart?

The number 167 is made of the digits 1, 6 and 7.

We can use a place value to chart to express the number 167 like this:

HundredsTensOnes
167

In other words, 1 hundred, 6 tens and 7 ones.

This number can also be represented in other ways without using numbers. Each pictorial representation in the slideshow below shows 167.

A place value chart can also use dots to represent the digits. The dots can be counted to find 1 hundred, 6 tens and 7 ones.

Remember, if the digits were put in a different order, the number would change completely.

Example 2

Let's rearrange the digits 1, 6 and 7 into 671 to see how it changes the number.

Place value counters

 

 

The same digits have been used but they are in a different order. Their value completely changes.

Example 3

Ellie wants to show the number 345 using place value counters. Can you help her?

The first thing you need to do is partition the number. That's 3 hundreds, 4 tens and 5 ones.

3 hundreds

4 tens

5 ones

Now put them together to represent 345:
