Following my post, Learning Mathematics, the slide set here is on Learning & Teaching GCSE Mathematics from the session I delivered at the excellent Somerset Professional Development Proramme February 2017.
Lots of pages, but if you are interested then the best way to view is via these files:
Learning & Teaching GCSE Mathematics PowerPoint and Learning & Teaching GCSE Mathematics for the pdf file. The pdf version seems much faster to operate if you wish to use all the embedded hyperlinks to the various resources. Note the table of contents which allows for navigation through the various pages.
On Slideshare – you can see the slides – hyperlinks will lead you to all the resources but for slide to slide navgation use the files above.
