In this 33-slide lesson, pupils will explore how quantities change over time through growth and decay processes. They will use the compound percentage formula to model repeated percentage change and apply this to real-world contexts such as population growth, financial depreciation, and rates of decline. The lesson also introduces exponential graphs, where pupils will learn to interpret and use them to find missing coordinates and constants in exponential equations. The lesson will deepen their understanding of how exponential functions represent change in various scenarios.
