'Graph' means 'picture'...

... as in 'geography', 'graphic novel', and so forth. Many students have a hard time grasping the idea of a graph as a visual representation of an equation; they confuse the coordinate grid with the graph, and think of graphing in terms of a list of incomprehensible 'steps'.

Dan Meyer is doing great things about that, and if I am not too late already my students may get to see the light, or rather to get the picture, some time over the next two weeks.
