Description

This unit helps pupils understand rounding to different decimal places, and significant figures. Pupils will also learn how to truncate numbers and understand the contexts in which these skills are useful. The unit ends will an exploration of rounding and inequality errors.

Students up to this point have been working with integer values and have had few opportunities to work explicitly on estimation. We are starting the year with something that is familiar for students and extend knowledge of estimation and rounding to include more work on rounding with decimals and significant figures.
