Counting backwards in 100s: step-by-step example
29 October 2026
Counting backwards in 100s helps children spot patterns and build confidence with place value. It is a key skill for 11+ and KS2 maths, especially when working with larger numbers. Use this clear example to show your child how to take each step calmly and accurately.
Worked example
Start at 800. Count backwards in 100s for three steps.
Step 1: 800 - 100 = 700
Step 2: 700 - 100 = 600
Step 3: 600 - 100 = 500
The correct answers are 700, 600, 500.
Key insight: Once your child can count backwards in 100s, they will find it easier to solve number problems and spot sequences. The next step is to practise similar questions, building speed and accuracy with each attempt.
