## Hurdles Race

#### A Visual Aid

This activity presents a distance/time graph as a real, living graph. The notion of passing time is simulated by the slow reveal of the graph from left to right. A student volunteer giving a live commentary is interpreting the meaning of the graph in a very vivid, familiar way.

The controls at the bottom right of the panel above can be used by the teacher to control the progress of the race. Running it a second or third time will allow your student commentator to improve their performance.

Introducing distance-time graphs is best done using the Helicopter View animation.
