Explain how making the dividend 100 times the size affects the quotient
Lesson details
Learning outcome
I can explain how making the dividend 100 times the size affects the quotient
Key learning points
- If the dividend is multiplied by 100 then the quotient will be one hundred times the size.
- The dividend is equivalent to the product in the inverse calculation.
- 18 divided by 6 is equal to 3 so 1,800 divided by 6 is equal to 300 or 18 hundreds divided by 6 is equal to 3 hundreds.
Keywords
Dividend - The dividend is the number being divided.
Divisor - The divisor is the number we are dividing by.
Quotient - The quotient is the result after division has taken place. It is a whole number.
Common misconception
Place value counters don't have proportionality in the same way that Base 10 blocks do which can make the concepts here more abstract.
Smaller divisions can be used with Base 10 to model scaling to start off with. Try 2 ÷ 2 or 4 ÷ 2 scaling up to become 200 ÷ 2 or 400 ÷ 2 with Base 10 and then put this modelling side-by-side with place value counters to make the links.
Teacher tip
Times table recall is very useful in these lessons. If some of your pupils are less confident with recall, consider scaffolding with a multiplication grid or adapting tasks to multiplication tables they are more familiar with.
