A set of increasingly-challenging ICT-based student quizzes that helps them to think carefully about co-ordinates. Includes fractional co-ordinates, asymmetric co-ordinate scales, simple transformations, and the visual skills to 'know&' where to add a 4th (missing point) required to complete a rectangle. If you download, then please leave feedback. If someone makes a Flash version of this and re-shares that&';d be better. I used Excel and although I 'protected&' the worksheet (to prevent accidental changes), the p/w is included on the front page so you can modify anything if you wish).
