Welcome to our Expanded Form to Standard Form Worksheets area.
Here you will find our free worksheet generator for generating your own place value worksheets to convert numbers from expanded form into standard form.
We also have step-by-step instructions and worked examples to show you how to master this skill.
Standard form is the usual way of writing number using digits.
Expanded form is when you write the place value of each digit separated by addition symbols (+).
Getting students to convert between standard form and expanded form is a great way of developing place value skills and think about what each digit of a number represents.
Note: in the US and other countries, the term standard form is used to mean decimal notation (the usual way we write numbers). However in the UK the term 'standard form' is used to mean standard index form or scientific notation.

Your worksheet will appear below.
Follow these step-by-step instructions to convert a number from expanded form to standard form.
We are going to convert 8 + 3000 + 200 into standard form using a place value chart.
Step 1) Make sure the numbers in the expanded form are in order, with the highest value number with the most digits first and the smallest number at the end.
Example: 8 + 3000 + 200 rewrite this as 3000 + 200 + 8.
Step 2) Take the first (largest) number to add and write down the digit in the correct place in the chart.
If you don't have a place value chart, then write down the digit followed an underscore for each of the zeroes in the number, so for 3000 we write down 3 _ _ _
The largest number is 3000 so we put 3 in the thousands column.
Step 3) Take the second number to add and write down the digit in the correct place in the chart.
The second number to add is 200, so we put a 2 in the hundreds column.
Step 4) Take the last number to add and write down the digit in the correct place in the chart.
The last number to add is 8, so we put this in the ones column.
Step 5) When you have finished writing down all the digits, look at the chart and put a zero in any columns with no digits. These are called placeholders.
There are no digits in the tens column so we need to put a 0 in the tens place in the chart as a placeholder.
So our final answer is 8 + 3000 + 200 = 3208.
The placeholder is very important - without it we get 8 + 3000 + 200 = 328 which is incorrect and is a common mistake for students to make.
In our examples, we convert numbers up to thousands to standard form, and also show how to convert decimals with up to 2 decimal places.
Here is a place value chart which shows place value up to 4 digits and up to 2 decimal places.
The expanded form is in the correct order (hundreds + tens + ones) so we do not need to rewrite this.
We have 300, so the hundreds digit is 3. We write down 3 _ _
We have 80, so the tens digit is 8. We fill in the tens digit: 3 8 _
We have 2, so the ones digit is 2. We fill in the ones digit: 3 8 2
There are no missing digits, so we have finished.
So 300 + 80 + 2 = 382
The expanded form is in the correct order so we do not need to rewrite this.
We have 6000, so the thousands digit is 6. We write down 6 _ _ _
We have 50, so the tens digit is 5. We fill in the tens digit: 6 _ 5 _
We have 7, so the ones digit is 7. We fill in the ones digit: 6 _ 5 7
There is a missing digit in the hundreds place, so we put a zero as a placeholder: 6 0 5 7
So 6000 + 50 +7 = 6057
The expanded form is not in the correct order, so we will rewrite it.
200 + 4 + 5000 = 5000 + 200 + 4
We have 5000, so the thousands digit is 5. We write down 5 _ _ _
We have 200, so the hundreds digit is 2. We fill in the hundreds digit: 5 2 _ _
We have 4, so the ones digit is 4. We fill in the ones digit: 5 2 _ 4
There is a missing digit in the tens place, so we put a zero as a placeholder: 5 2 0 4
So 200 + 4 + 5000 = 5204
The expanded form is in the correct order so we do not need to rewrite this.
We have 70, so the tens digit is 7. We write down 7 _ . _
We have 8, so the ones digit is 8. We fill in the ones: 7 8 . _
We have 0.5, so the tenths digit is 5. We fill in the tenths digit: 7 8 . 5
There are no missing digits, so we have finished.
So 70 + 8 + 0.5 = 78.5
The expanded form is not in the correct order, so we will rewrite it.
5 + 400 + 0.08 = 400 + 5 + 0.08
We have 400, so the hundreds digit is 4. We write down 4 _ _ . _ _
We have 5, so the ones digit is 5. We fill in the ones: 4 _ 5 . _ _
We have 0.08, so the hundredths digit is 8. We fill in the hundredths digit: 4 _ 5 . _ 8
There are 2 missing digits, so we need to fill them in with zeroes: 4 0 5 . 0 8
So 5 + 400 + 0.08 = 405.08
We have a selection of place value charts which are great for helping to develop understanding of place value.
As you can see from the example above, the charts can also be really useful for students who are struggling to convert numbers from expanded form to standard form.
The charts cover a range of numbers from millions to thousandths.
They are also a good way to get children to become familiar with how the number system works.
Here are some of our other related worksheets you might want to look at.
Our standard form to expanded form worksheets generator will let you create your own place value worksheets to convert numbers from standard form to expanded form.
You can choose whether to randomize the place value addends, choose your number values up to millions or decimals up to 3dp.
