Rearranging formulae B is suitable for students aiming for or with a target grade of 7 or higher. This bumper worksheet contains twenty-nine questions that require learners to change the subject of given formulae. Questions get harder as the worksheet progresses making it easy to direct individuals to different questions on the worksheet. Multiple different variables are used throughout and in some equations, the subject appears more than once. Students will have to collect terms together and will often be required to expand and/or factorise in order to do so.

Students may have slightly different answers to their peers or our answer sheet. This provides a good point for discussion as to whether two different answers are equivalent.
