In this lesson, students explore a scenario involving two robots, each moving at a (different) constant speed along the same straight line. Students draw distance-time graphs to describe the movement of the robots and predict when and where they will meet.
Increasingly complicated scenarios can all be modelled with the same graphical approach, allowing students to see the power of graphical representations to make sense of situations.
Why teach this?
Many real-life problems involve speed, distance and time. Representing motion using distance-time graphs can be very helpful in making sense of complicated situations.
