In this lesson
In this video you'll learn about using and rearranging a formula (subject appears once) for GCSE Maths, with worked examples and the mistakes examiners report. By the end you'll be able to locate and correctly use a given standard formula, then rearrange a formula to make a different subject when that subject appears only once.
What it covers
- 1:04 Using a given formula
- 3:23 Rearranging, the why
- 5:39 One step, another subject
- 6:55 Your turn now, on a formula built the same way as the one just worked through
- 7:58 Exam technique

For teachers
This GCSE Maths lesson teaches using and rearranging a formula (subject appears once). By the end, students should be able to locate and correctly use a given standard formula, then rearrange a formula to make a different subject when that subject appears only once. It works through three worked examples and the mistakes examiners report.
