Place value

A place value table with three columns. In the hundreds column is the number 4, in the tens column is the number 2 and in the ones column is the number 5.

Numbers are made of digits.

Where a digit is placed in a number tells you what value the digit has.

You can use place value headings, like ones, tens and hundreds, to help you understand the value of each digit.

Understanding place value

There are only ten digits that you can use to write any number. These are:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9

When only one digit is used, such as 4, it represents 4 ones.

When two digits are used, for example in the number 54, the digit 4 still represents ones, but the digit 5 represents 5 tens, which is 50.

50 + 4 = 54

When three digits are used, such as in the number 354, the digit 4 represents ones, the 5 represents 5 tens, and the 3 represents 3 hundreds, which is 300.

300+ 50 + 4 = 354

It is important to write the digits in the correct places so that they represent the correct values.

You can use place value counters and part-whole models to help you understand place value.

In the ones column there are 4 ones counters., Take a look at these place value counters. What number do they represent?

Example 1

A place value chart with three columns. In the hundreds column there are 6 sets of one-hundred squares. In the tens column there are 5 stacks of ten cubes. In the ones column there is 1 cube.

What number does this place value chart represent?

Example 2

A place value chart with three columns. In the hundreds column there are five 100-counters. In the tens column there are 6 10-counters. In the ones column there are 4 1-counters.

What number do these place value counters represent?

Example 3

The numbers 856 has been partitioned into 3 numbers. the first number is blank, the second number is 50 and the third number is 6.

What number is missing from this part-whole model?
