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.
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.
Common misconception
The short division algorithm may not be correctly aligned.
Check that the decimal point aligns in the decimal fraction and the answer.
