Thank you for sharing, useful resource which can be used as a worksheet, or put on screen using a data projector.

This is a nice plenary where students have to match up an equation to a graph using transformations or other observations. You could use this with Core 1 students or high ability KS4 students. You could easily cut and paste this into a powerpoint so that you can display it on the IWB, students could give their answers on mini whiteboards to provide some discussion. Thank you for sharing.
