Upper & Lower Bounds: Explorative Learning

This lesson has been designed for students to be able to work independently on identifying upper and lower bounds, and using them in calculations.

The questions posed should be sufficient for students to have little teacher input, but instead students should work through the questions, working collaboratively with one another, and checking answers as they progress.
