[Blindmath] measuring angles

[Jaquiss, Robert]

Hello:

     I haven't seen an APH protractor, so I don't know how hard it would be to use. When I took Trigonmetry, I used a protractor with a movable pointer and also an ordinary plastic protractor that had raised markings. For the later, I counted up the degrees from one side. Learning to use a protractor is a necessary skill. In case you wonder, I am totally blind.

Regards,

Robert

Subject: [Blindmath] measuring angles

Please give me some ideas as to how to teach a student to measure angles. I am using the American Printing House protractor, and the Graphic aid from APH(Consists of a cork board mounted with a rubber mat embossed with a 34 x 30 grid of 1/2 inch squares. ) I am constructing the angles with rubber bands, and push pins, or they are prepared using embossed angles paper. 

The process is so encumbered! Does anyone have any suggestions? Thanks, M
