This is a complete lesson on composite functions and includes a mastery worksheet within the PowerPoint.
The lesson includes a starter activity based on substituting values into functions.
A clear explanation on what a composite function is and how to calculate composite functions.
4 full examples on calculating composite functions. (2 with an input of a number, 2 with an input of a variable)
A few questions for the students to try altogether before the worksheet.
A mastery worksheet split into 3 sections (fluency, reasoning and problem solving) so students can master the topic. It also includes an AQA UK exam question at the end so students can see how many marks would be awarded in the exam.
Answers for the worksheet.
Plenary question getting students to spot the mistakes.
If you would like to change the year in the PowerPoint (I have taught this topic to year 10 in the UK) all you need to do is to view slide master and change the master slide.
