Lesson details
Key learning points
- In a subtraction equation, when the subtrahend is one less than the minuend, all except one is subtracted.
- Numbers that are one more or one less than each other are called consecutive numbers.
- Consecutive numbers have a difference of one.
- Spotting consecutive numbers in subtraction equations can help us to solve equations more quickly.
Keywords
Difference - The result of subtracting one number from another.
One less - The number before a given number is one less than it.
Consecutive - Numbers which follow each other in order, without gaps.
Common misconception
Children may resort to counting strategies to find the difference e.g. counting back four from five to solve 5 - 4
Always make a clear link between 'all except one' object leaving, and the subtrahend being one less than the minuend.
