This page contains scans of all 823 overhead transparencies that I created when I was a high school mathematics teacher in Melbourne, Australia, from 1997 to 2006.

The pages are numbered in the order that I created them, and so represent a mixture of topics from Year 8 to Year 12 level. I actually wrote each number on the bottom corner of each transparency, which let me figure out where to find each of them (stored in a number of pocket binders with plastic sleeves). I added letters (‘a’, ‘b’, etc.) when I found that I needed to cut a transparency into parts, so that I could use just a part of it (one subtopic) in a course different from the one that it was originally created for.

Hence, the only way to find any particular topic is to search for it on this page! Sorry. (When I was teaching, I would create a page for each module of work for each subject, which linked to these notes in the correct order.)

Anything in a title between square brackets was added at the time to this collection page, and represents text not in the title of the overhead transparency itself.
