Approximation is an important part in GCSE maths. In this lesson students will learn how to calculate the upper and lower bounds of different values. For example, If a number or measurement has been rounded, it can be important to consider what possible values the exact value could have been. To describe all the possible values that a rounded number could be, we use lower and upper bounds. This class is aimed at students in Years 9 - 11 who want to be prepared for their maths GCSE!
