Distance/Time graph game (amazing)

The smart notebook is pretty simple, it is what you choose to make out of it. Push aside your tables and get out the masking tape. Tape up 1 m intervals from a wall up to 5m. Let two students compete against one another (although of course it isn't a race) and act out the displacement time graph. They instantly get a feel for stationary points, constant speeds, changes in direction etc. Get other students to predict what is going to happen first on mini whiteboards and judge the two competitors. I have taught this at open evenings, to german exchange students, years 7-11.
