All students complete initial, basic card matching exercise.
They then attempt the extension card matching/creation activity to varying degree of depth.
Slide 9 (going through the answers) is to be completed by asking pairs of students for their answers, a justification, and handwriting answers in box on whiteboard. ALSO ask students about the shape of the associated graph – they will have made notes on their whiteboards (I can draw/discuss the graphs on a separate whiteboard).

Matching Functions and their DerivativesPAUSE
We will check answers in a minute.
But first, write some notes on whiteboards about the graph of each of the functions.
