In this lesson, learners will be able to :
- round numbers and measures to an appropriate degree of accuracy [for example, to a number of decimal places or significant figures].
- use approximation through rounding to estimate answers and calculate possible resulting errors expressed using inequality notation a<x≤b.
- apply and interpret limits of accuracy when rounding or truncating
Lesson can be used as whole class teaching by teachers and at home by learners.
