Interactive PowerPoint for GCSE Maths: covers translation, reflection, rotation and enlargement. Works best when projected onto a whiteboard (not necessarily an interactive one) but can also be viewed/used on screen by individuals.
New improved version (Oct 2017) includes enlargement with negative scale factor, invariant points and an accompanying worksheet (in both Word and PDF format). There are two versions of the PowerPoint: the (editable) original and a slideshow version (identical in content) suitable for upload to your VLE for student use.
May 2018 - error on first diagram (a discrepancy from the slide it was supposed to match) on worksheet corrected.
Apr 2020 - added vertical and horizontal arrows to make angle of rotation easier to see.
