I am an experienced teacher dedicated to creating fantastic resources that engage pupils. My resources give teachers examples that they can model with pupils before giving pupils the chance to practice plenty of example questions. My pupils love answering questions using the catchphrase activity - I have found it really keeps them on task and engaged (especially if there is a small prize for whoever answers the catchphrase correct!)

Transformations - GCSE Maths Revision

(2)
This resource covers both performing and describing transformations. It is designed as a revision resource for foundation AQA students prior to their GCSE examination. It is in publisher and can be printed as a booklet onto A3 paper (folded) in order to turn it into an A4 booklet. There is four pages. Page 1 - teacher demonstrates the four transformations (see image). Page 2 - six practice questions that ask students to perform a variety of transformations / combined transformations. Page 3 - teacher demonstrates how to describe transformation. Page 4 - eight questions that ask students to describe single transformations. Pages 1 and 3 are included in the powerpoint presentation should the teacher wish to demonstrate on the board. Personally, I think it is best to use a visualiser. It covers transformations, reflections (including y=x), rotations and enlargements (positive and fractional). It therefore covers topics tested on AQA Foundation grade 1 to grade 5.
