This unit of work is on Accuracy and Bounds.
Accuracy and Bounds are often difficult ideas to teach because students find it challenging to consider the least and greatest values which would round to a particular number.
We are going to look at how to identify the upper and lower bounds for data given to a specified accuracy.
We will look at identifying the bounds for data given to the nearest 10, 100, 1000 or to a specified number of decimal places or significant figures and use these results to find the solutions to simple problems.
This unit of work is just one of several approaches that you could take when teaching this topic and you should aim to adapt the resources to match ability level of your learners as well as your school context.
