Project Math Access DVD 04 - Facilitating Inclusion - Part 02 Transcript Start Audio Description: Part two; Nemeth code reference sheet. Teacher: To help me with Geometry and a lot of the symbols for line segments and rays and lines and parallel and perpendicular and not parallel, and etc., I made up just a little cheat sheet where I did the, brailled the symbol and an example of the problem and then what it was. And this came in very handy when a lot of the symbols weren't used a lot, because then I would be able to quickly look it up instead of having to go through the Nemeth book and keep looking the information up in the book. Audio Description: The names are handwritten in ink above braille.
