Use different strategies to subtract multiples of 100
Lesson details
Learning outcome
I can use different strategies to subtract multiples of 100
Key learning points
- Known facts help us to subtract multiples of 100
- If 5 subtract 3 is equal to 2 then 5 hundred subtract 3 hundred is equal to 2 hundred.
- Subtracting multiples of 100 can be represented in different ways.
Keywords
Multiple - A multiple is the result of multiplying a number by another whole number.
Common misconception
Pupils may not see the connection between known facts and calculating using multiples of one hundred.
Place value counters or Base 10 blocks may be helpful with getting children to unitise and see the connection between, for example, 14 − 7 and 1,400 − 700
Teacher tip
Pupils may find number lines helpful for this session (number lines counting in multiples of 100 up to 2,000), Pupils could use ten frames and place value counters instead. Encourage pupils to discuss strategies for calculating subtraction with multiples of 100, especially with numbers over 1000
