A fantastic guide. It would be great to have an external link to this resource too, so that any local school content includes just the link to the current version. A few lines of local code rather than myriad potentially outdated copies of the file (4MB).

Have you tried the teaching guide to Mechanics in the resources tab on the Edexcel A Level Maths page? It's designed for teachers who are new to Mechanics

Cheers. This looks brilliant and will prove really useful to students as I suspect this calculator will be common among A level students. Just one note - slide 17 says the log base 10 button is gone: it's actually hiding on the Shift & minus button.

This is excellent thanks Jamie. Minor slip - you refer to 'mode' button rather than 'menu' in the slide for 'alpha' button.
