29 October 2026

Understanding what it means to find 100 more than a number is a key skill for building number confidence. It helps children see how numbers change when we add to the hundreds place, without needing to count every single one.

Example question
What is 100 more than 345?
Step 1: Look at the number 345. It has 3 hundreds, 4 tens, and 5 ones.
Step 2: To find 100 more, add 1 to the hundreds digit (3 + 1 = 4).
Step 3: Keep the tens and ones the same (4 tens and 5 ones).
Step 4: The new number is 445.
Answer: 100 more than 345 is 445.
After working through this example, your child will be able to spot the hundreds digit and add 100 quickly. This prepares them for similar questions in 11+ practice, where they can apply the same method with different numbers.
