The lesson start by establishing what the student know already about distance time graph. The lesson then moves onto modelling how to calculate speed from several examples on the graph. As an AFL opportunity there is an inbuilt hinge point question, diagnostic of understanding. The outcome of the HPQ directs student to a gold, silver or bronze task all based on the same graph. The students demonstrate their knowledge by drawing their own graph with an extension task if needed. The lesson concludes with an exit ticket.
