A Picture Is Worth a Thousand Exercises
Foster, Colin
Mathematics Teaching, n224 p10-11 Sep 2011
One sign of a good task is that it will work just as well with Year 7 as with Year 13. The author asks learners to use graph-drawing software to draw a picture with graphs. He uses his imagination to suggest what a particular curve might resemble and helps learners to adjust their drawings to achieve what they are trying to make. Sometimes, one learner creates a picture and conceals the equation(s) and others try to replicate it, as near as they can. Working in this way involves learners in a great deal of productive mathematical thinking and would seem to be worth any number of dreary exercises on "transformations of graphs".
