Ordering Large Numbers: Step-by-Step Example
23 October 2026
Ordering large numbers can seem tricky at first, but it becomes much easier when you break it down into simple steps. By looking at the number of digits and comparing each digit from left to right, your child can confidently find which numbers are smaller or larger.
Worked example
Order these numbers from smallest to largest: 5,847; 5,792; 56,432; 56,891
Step 1: Look at how many digits each number has.
5,847 and 5,792 have 4 digits.
56,432 and 56,891 have 5 digits.
Step 2: Numbers with fewer digits are smaller, so 5,847 and 5,792 come before the others.
Step 3: Compare 5,847 and 5,792 digit by digit from left to right.
Thousands place: both have 5.
Hundreds place: 8 in 5,847 and 7 in 5,792. Since 8 is bigger than 7, 5,847 is bigger than 5,792.
Step 4: Compare 56,432 and 56,891 digit by digit.
Ten thousands place: both have 5.
Thousands place: both have 6.
Hundreds place: 4 in 56,432 and 8 in 56,891. Since 4 is less than 8, 56,432 is smaller.
Step 5: Put all numbers in order from smallest to largest:
5,792 < 5,847 < 56,432 < 56,891
The correct answer is: 5,792, 5,847, 56,432, 56,891
| Number | Number of digits |
|---|---|
| 5,847 | 4 |
| 5,792 | 4 |
| 56,432 | 5 |
| 56,891 | 5 |
After working through this example, your child will recognise how to compare and order large numbers by checking digits and place value. There are more questions just like this ready to practise, helping them build confidence for the 11+ maths exam.
