Place Value

Thousands for primary learners

Extend place value beyond hundreds with real-life large-number contexts.

Quick answer

Thousands are numbers that have four digits, like 1,000, 2,000, or 10,000. They come after hundreds in our number system. You can think of thousands as groups of 100s, so 1,000 is 10 groups of 100, or 100 groups of 10.

Learning outcome

By the end of this page, you will understand how thousands work in numbers and be able to count, read, and write numbers up to 10,000. Success signs:
  • You can say the number 1,000, 2,000, 3,000, and so on, all the way to 10,000.
  • You can show how many hundreds are in 1,000, 2,000, or 5,000.
  • You can write numbers like 3,456 and say what each digit means.
  • You can use real-life examples to understand how big thousands are.

Why this matters

Understanding thousands helps you read big numbers in real life, like how many people live in a city, how much money you have, or how far you’ve walked. It also helps you prepare for bigger maths, like addition, subtraction, and multiplication with large numbers. When you learn about thousands, you’re getting ready for bigger numbers and more complex problems in maths.

How it works

Numbers with thousands have four digits. The first digit is the thousands place, then hundreds, tens, and ones. Here's how it works:
  1. The first digit from the left is the number of thousands.
  2. The second digit is the number of hundreds.
  3. The third digit is the number of tens.
  4. The fourth digit is the number of ones.
For example, in the number 3,456:
  • 3 is in the thousands place – that means 3,000
  • 4 is in the hundreds place – that means 400
  • 5 is in the tens place – that means 50
  • 6 is in the ones place – that means 6

Examples you can see

Let’s look at some examples to understand thousands better: Example 1: 1,000
  • 1,000 means 1 group of 1,000
  • This is the same as 10 groups of 100
  • Or 100 groups of 10
Example 2: 2,345
  • 2 is in the thousands place – so 2,000
  • 3 is in the hundreds place – so 300
  • 4 is in the tens place – so 40
  • 5 is in the ones place – so 5
So, 2,345 = 2,000 + 300 + 40 + 5 Example 3: 10,000
  • 10,000 means 10 groups of 1,000
  • This is the same as 100 groups of 100
  • Or 1,000 groups of 10

Try it as a mini adventure

Adventure: The Big Numbers Challenge You are a treasure hunter and you’ve found a map that leads to a chest full of gold coins. The chest is locked with a number code. The code is 4,567. To open the chest, you must understand what each digit means.
  1. First, you need to find the thousands place. What is the thousands digit in 4,567? (Answer: 4)
  2. Next, you need to find how many hundreds are in 4,567. (Answer: 5)
  3. Then, you need to find how many tens are in 4,567. (Answer: 6)
  4. Finally, you need to find how many ones are in 4,567. (Answer: 7)
Great job! You’ve opened the chest with the code 4,567. Now you can count how many coins you’ve found!

Common mistakes

  • Mistake: Thinking that 1,000 is the same as 100.
    Why it happens: Confusing the number of digits.
    Fix: Remember that 1,000 has 4 digits, and 100 has 3 digits.
  • Mistake: Mixing up the place values.
    Why it happens: Not knowing which digit is in which place.
    Fix: Count from left to right: thousands, hundreds, tens, ones.
  • Mistake: Writing 1,000 as 1000 (without a comma).
    Why it happens: Not understanding that commas help us read big numbers.
    Fix: Always use commas after every three digits from the right.

Parent and carer guide

As a parent or carer, you can help your child understand thousands by:
  • Practising reading numbers like 3,456 and asking them to tell you what each digit means.
  • Using everyday items to show how many hundreds make up a thousand (e.g., 10 groups of 100 coins = 1,000 coins).
  • Playing games with numbers, like asking your child to make a number with 4 digits using base-10 blocks or counters.
  • Using real-life examples like the number of people in a town or the number of pages in a book to show how big numbers can be.
  • Encouraging them to write numbers in expanded form (e.g., 2,345 = 2,000 + 300 + 40 + 5).

Practice questions

  1. What is the value of the digit 5 in 4,567?
  2. Write the number 6,789 in expanded form.
  3. How many hundreds are in 3,000?
  4. What number has 8 thousands, 4 hundreds, 2 tens, and 5 ones?
  5. Count by 1,000s from 1,000 to 10,000.
Answers:
  1. 500 (because 5 is in the hundreds place)
  2. 6,000 + 700 + 80 + 9
  3. 30 (because 3,000 ÷ 100 = 30)
  4. 8,425
  5. 1,000, 2,000, 3,000, 4,000, 5,000, 6,000, 7,000, 8,000, 9,000, 10,000

FAQ

What is a thousand?

A thousand is the number 1,000. It is 10 groups of 100, or 100 groups of 10.

How do I read big numbers like 5,678?

You read it as "five thousand, six hundred seventy-eight". Each digit tells you how many thousands, hundreds, tens, and ones there are.

Why do we use commas in big numbers?

Commas help us read big numbers more easily. They separate every three digits from the right, so we can tell how many thousands, hundreds, tens, and ones are in the number.

What comes after 9,999?

After 9,999 comes 10,000. This is the first number with five digits.

Can I use base-10 blocks to learn about thousands?

Yes! You can use blocks to show how 10 groups of 100 make 1,000, or 100 groups of 10 make 1,000.
