Place Value to Thousands
A clear primary math lesson on place value to thousands: read 4-digit numbers, use a place-value chart, expand numbers, and practise with worked examples and a quiz.
Key takeaways
- A 4-digit number has four places: thousands, hundreds, tens and ones
- Each place is worth 10 times the place to its right
- The number 3,482 means 3 thousands, 4 hundreds, 8 tens and 2 ones
- Zero is a place-holder that keeps every other digit in its correct place
What is place value?
Every number is built from digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
But the same digit can mean very different amounts. The place a digit sits in tells you what it is worth. This idea is called place value.
You already know two places from Place Value: Tens and Ones. Now we add two more places so we can read numbers all the way up to 9,999.
The four places
In a 4-digit number, there are four places. Reading from the right, each place is ten times bigger than the one before it.
| Place | Worth | Example digit | Means |
|---|---|---|---|
| Ones | 1 | 2 | 2 |
| Tens | 10 | 8 | 80 |
| Hundreds | 100 | 4 | 400 |
| Thousands | 1,000 | 3 | 3,000 |
Why ten times? Our number system is built on groups of ten. Ten ones make one ten. Ten tens make one hundred. Ten hundreds make one thousand. This pattern never stops, which is why the same ten digits can build any number.
Reading a 4-digit number
Take the number 3,482.
- The 3 is in the thousands place โ 3 thousands = 3,000.
- The 4 is in the hundreds place โ 4 hundreds = 400.
- The 8 is in the tens place โ 8 tens = 80.
- The 2 is in the ones place โ 2 ones = 2.
Now add the parts together:
3,000 + 400 + 80 + 2 = 3,482
We read it as "three thousand, four hundred and eighty-two."
The place-value chart
A chart lines up the digits so you can see each place clearly.
| Number | Thousands | Hundreds | Tens | Ones |
|---|---|---|---|---|
| 1,256 | 1 | 2 | 5 | 6 |
| 4,609 | 4 | 6 | 0 | 9 |
| 7,000 | 7 | 0 | 0 | 0 |
| 2,073 | 2 | 0 | 7 | 3 |
Notice the zeros. In 4,609 the zero sits in the tens place. It tells us there are no tens, but it must stay there to keep the 6 in the hundreds place and the 9 in the ones place. Without the zero, the number would shrink to 469 โ a completely different value. A zero is a place-holder.
Worked example 1: build the number
Build the number with 5 thousands, 3 hundreds, 0 tens and 9 ones.
- 5 thousands = 5 ร 1,000 = 5,000
- 3 hundreds = 3 ร 100 = 300
- 0 tens = 0
- 9 ones = 9
- Add them: 5,000 + 300 + 0 + 9 = 5,309
So the number is 5,309. The 0 keeps the tens place empty.
Worked example 2: expanded form
Write 6,150 in expanded form.
Expanded form means splitting a number into the value of each digit.
- The 6 is 6 thousands = 6,000
- The 1 is 1 hundred = 100
- The 5 is 5 tens = 50
- The 0 is 0 ones = 0
So: 6,150 = 6,000 + 100 + 50
We can leave out the 0 because adding zero changes nothing.
Worked example 3: comparing numbers
Which is bigger, 3,190 or 3,099?
To compare, line them up and check each place from the left (the biggest place first):
- Thousands: both have 3. Tied โ keep going.
- Hundreds: 3,190 has 1; 3,099 has 0. 1 is more than 0.
As soon as one number wins a place, you can stop. So 3,190 > 3,099.
Why check from the left? The leftmost place is worth the most. A single thousand outweighs every hundred, ten and one combined, so the biggest place decides first.
Try it yourself
Grab a pencil and paper, or use coins and counters.
- Write 2,407 and say what each digit is worth.
- Build the number with 8 thousands, 8 hundreds, 8 tens and 8 ones. (Answer: 8,888.)
- Put these in order from smallest to largest: 1,205, 1,250, 1,025.
Check the last one: line up the thousands (all 1), then hundreds โ 1,025 has 0, the others have 2, so 1,025 is smallest. The order is 1,025, 1,205, 1,250.
Great job!
You can now read, build and compare numbers up to the thousands. This is the foundation for adding and subtracting big numbers.

Quick quiz
Test yourself and earn XP
In the number 5,728, what does the 5 stand for?
The 5 sits in the thousands place, so it means 5 thousands, which is 5,000.
How many hundreds are in 4,609?
The hundreds digit is 6, so there are 6 hundreds (600). The 0 is in the tens place.
Which number is made of 2 thousands, 0 hundreds, 7 tens and 3 ones?
2,000 + 0 + 70 + 3 = 2,073. The 0 holds the hundreds place empty.
What is the expanded form of 6,150?
6 thousands + 1 hundred + 5 tens + 0 ones = 6,000 + 100 + 50 + 0.
Which number is the largest?
All start with 3 thousands. Compare the hundreds: 3,190 has 1 hundred, the others have 0, so 3,190 is largest.
FAQ
The comma separates the thousands from the hundreds so big numbers are easier to read at a glance. In some countries a space or dot is used instead.
Reading from the right: ones (1), tens (10), hundreds (100) and thousands (1,000). Each place is ten times bigger than the one before it.
