I can explain how making the dividend 10 times the size affects the quotient
Lesson details
Key learning points
- If the dividend is multiplied by 10 then the quotient will be ten times the size.
- The dividend is equivalent to the product in the inverse calculation.
- 18 divided by 6 is equal to 3 so 180 divided by 6 is equal to 30 or 18 tens divided by 6 is equal to 3 tens.
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 does 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 20 ÷ 2 or 40 ÷ 2 with Base 10 and then put this modelling side-by-side with place value counters to make the links.
Times table knowledge is very useful in this lesson. If you've pupils whose times table knowledge is less secure, give them a times tables grid to use so that they can focus on the key learning in the lesson. You could also plan to use examples involving times tables with which they are familiar.
