  4. Teaching Exemplars and Worksheets.
    The list below is a series (small so far) of worksheets submitted by the HP User Group in Western Australia.  These are simply worksheets that have worked for teachers in the group and that may be of use to others. If you have ideas then I would love to hear from you.



"This is a worksheet I have used to investigate the derivative of e that has worked quite well."

A paper with ideas to help when investigating derivatives of trig functions and ex.

This is a very nice investigation into piecewise defined linear function.  A validation test is included, plus fully worked solutions.

This is a wonderful activity that I did with my Intro Calc class which used piecewise defined functions to produce pictures.
