In this lesson, we will recap percentage of amounts using multipliers. We will practise and model finding percentages of amounts.

In this lesson, we will learn about percentage change. We will investigate how to increase or decrease an amount by a given percentage.

In this lesson, we will learn about how useful 100% is, and how we use it to solve various percentage problems.

In this lesson, we will learn about the cumulative effect of repeated percentage changes.

In this lesson, we will learn about elements of compound appreciation and depreciation.

In this lesson, we will learn about more elements of compound appreciation and depreciation.

In this lesson, we will learn about 'to the power of n'. We will invesigate patterns of exponential growth as the value of n increases for any given base.

In this lesson, we will learn about the exponential function and how it relates to powers of n.
