Understanding rate
In this lesson, we will learn about the term 'rate' and apply it to problems that provide a given rate and need scaling.

Conversion rates
In this lesson, we will learn about conversion rates that are in the same ratio, and those that change. We will model problems and solutions involving conversion rates.
Exchange rates with graphs
In this lesson, we will learn how to use and interpret conversion graphs to represent rates.
Density as rate
In this lesson, we will learn how to describe a rate of two specific variables as density.
Speed as rate (distance-time graphs)
In this lesson, we will learn that we can describe a rate of two specific variables as speed. We will also look at distance-time graphs.
Calculating speed, distance and time
In this lesson, we will learn to calculate and interpret speed, distance and time.
Displacement-time graphs (Part 1)
In this lesson, we will learn the difference between distance-time and displacement-time graphs.
Displacement-time graphs (Part 2)
In this lesson, we will think further about displacement-time graphs and when the relationship may or may not be linear.
