Divide decimal fractions by 1-digit numbers using written methods
I can explain how to use written methods to divide decimal fractions by 1-digit numbers.
Lesson details
Key learning points
- Use scaling to convert the decimal fraction to a whole number; after dividing, use scaling to adjust the answer.
- Short division can be used to divide; the decimal point in the answer must be aligned with that in the decimal fraction.
- Estimation should be used to sense-check answers.
Common misconception
The short division algorithm may not be correctly aligned.
Check that the decimal point aligns in the decimal fraction and the answer.
Keywords
Estimation - When we estimate, we find a value that is close enough to the right answer, usually with some thought or calculation involved.
Scaling - Scaling is when a given quantity is made ___ times the size. It can be used to adjust the size of a factor. In this lesson, scaling will involve making values 10 or 100 times the size.
