Lesson details
Key learning points
- Rounding and estimation are practical maths skills.
- They can be used to quickly estimate the cost of a project.
- Sometimes you will need to apply common sense to rounding in context.
Keywords
Upper bound - The upper bound for a rounded number is the smallest value that would round up to the next rounded value.
Lower bound - The lower bound for a rounded number is the smallest value that the number could have taken prior to being rounded.
Error interval - An error interval for a number x shows the range of possible values of x. It is written as an inequality a ≤ x < b
Common misconception
For example if a measurement of 12 cm has been given to the nearest centimetre assuming the upper bound is 12.4 cm.
Emphasise the infinite nature of a measurement.
