Comparing and ordering large numbers for 11+ maths
21 October 2026
Why comparing large numbers matters
Understanding how to compare and order large numbers is a key skill for the 11+ maths exam. It helps children work confidently with place value, solve word problems, and interpret data.
Step 1: Count the digits
Start by looking at how many digits each number has. A number with more digits is always greater than one with fewer digits.
Step 2: Compare digit by digit
If the numbers have the same number of digits, compare each digit from left to right. The first place where the digits are different tells you which number is bigger.
Step 3: Use comparison symbols
Use the symbols > (greater than), < (less than), and = (equal to) to show the relationship between the numbers.
Worked example
Compare 4,562,789 and 4,562,798
Step 1: Both numbers have 7 digits, so move to the next step.
Step 2: Compare each digit from left to right: 4 = 4, 5 = 5, 6 = 6, 2 = 2, 7 = 7, 8 < 9.
Step 3: The sixth digit in the second number is greater, so 4,562,798 is larger.
The correct answer is 4,562,789 < 4,562,798.
Practical tip for parents
Encourage your child to practise comparing numbers using real-life examples, such as house prices, population figures, or numbers from news articles. Regular practice builds confidence and accuracy.
Key insight: Comparing and ordering large numbers is a fundamental skill for 11+ maths and can be mastered through simple, step-by-step practice with clear examples.
