I live, teach Maths, and bake bread in Birmingham, UK. Contact me at

I've worked for 30+ years in post-compulsory and adult education. I have experience in staff development, teacher training and curriculum design in addition to teaching maths at a variety of levels. I have written course materials working with an editor and a multimedia team. I'm currently working as a classroom assistant which is proving to be very interesting - a different skill set from class teaching.

GCSE Maths materials [pdf]

Shape facts slides
Angle facts, vocabulary and conventions. Each fact illustrated on one slide. Polygons, regular and irregular, including quadrilaterals and triangles. Parallel lines and all. Can be printed 16 up on A3 as flashcards or printed A3 per slide as posters.
Probability Rules and Tools
GCSE Foundation maths notes on probability. Includes probability formula, scale and vocabulary, OR rule, AND rule, possibility space diagrams, tree diagrams and two way tables. A few pages on set notation and Venn diagrams. For students who like reading and for me to clarify my Probability story so I can write a problem set.
200 pages of GCSE Maths questions
Just in case they come in useful. Mostly Foundation tier and written to the English national curriculum. Many don't have answers or solutions.
Number topic guide
Explains the vocabulary and methods (both visual and symbolic) used in GCSE foundation tier maths. I've tried to make the layout as clear as possible for students with moderate dyslexia. Seems to work better for everyone.
Maths place mats
These are designed to be printed at A3. They work greyscale but look more engaging in colour. Each place mat has 16 questions. Some are one topic and some are mixed.
Probability Words
Just two sides with minimal vocabulary for foundation probability. The words students will see in revision guides and on videos.

Other stuff

GNU Nano quick guide [pdf]
A one side guide to some of the extended commands in the nano editor. I just used the help mode commands (the ones at the bottom of the screen) for years before I discovered ^G and the man pages. The official short cut guide covers similar material. Nano gets the job done for many people.
52:48 [pdf]
A pictorial representation of a strangely topical ratio.
