A really useful start to my lesson on conversion graphs. Once I had shown them the powerpoint they were away. The only extra reminders they needed was to draw the graphs big enough and chose scales which were easy to use.

Although this is a smart way to snap a ruler, problem with the resource is that it is not generalisable to other sets of conversions. I don't have a miles to kilometres ruler to break up and put one on each set of axes, or £ to $ scales. Also the 45 degree line may give students the impression that all conversion graphs will be like this, when in fact this will not be the case since the gradient of the line is not 1. Also scales on square paper ought to have 'nice' numbers linked to the grid lines.
