Exponential Growth and Decay
This activity provides a full lesson plan with starter (simulating radio-active decay), main activity (compound interest) and plenary.
The learning objectives are:
- Recognise graphs of exponential growth and decay;
- Find the link between exponential growth and decay and a multiplier;
- Know the general form and the properties of an exponential curve.
The pdf file provides teachers with detailed guidance on presenting the lesson assuming that students start with a new blank tns document, but an alternative method is to use the pre-formed tns file, Exponentials.
