[Blindmath] Measuring Angles using the APH Braille/Print Protractor

Thu Jan 5 19:26:39 UTC 2012

Hi Maureen,

Yes, this protractor is from APH. It is called the APH Braille/Large Print
Protractor. It is on page 48 of the 2011-2012 APH print catalog. The order
number is 1-04115-00 and the cost is $14 on Federal Quota funds. The one I
am using in the video is plastic. In fact way back in Part 1 and 2 I talk
about how it is made from a flexible plastic that allows measuring angles in
a textbook that are close to the binding. Now, there have been two versions
of this protractor. The first one which I definitely used in Part 13 was the
original version where the protractor has more print detail. The company
that made the protractor changed to a different plastic which would not
tolerate the braille dots (the pressure of adding the dots cracked the
plastic), so APH had to start making the protractor part as well as the
wand. However, that is the only difference between the two protractors. They
are both plastic. A braille reader (with no vision) wouldn't even realize
they were different. I show you both versions in Part 1 of the videos. I
would never teach one of my blind students from the video alone. We always
have our hands over and under each others and all over the angle and the
protractor. So, the student knows exactly which angle we are talking about
when I say "this angle."

Thanks Susan these are great. I notice you are using a different protractor
than I have. Did you get it from APH? I can't find it in the catalogue. Only
a plastic one seems to be in there. I must be missing something?!

As I mentioned earlier, the APH Braille/Print measuring videos are actually
available on YouTube. They just aren't accessible via that distance ed
website. Here are the "horrible" links for now if it was too much trouble to
do the search.

I've also attached that Canadian article I mentioned from Tammy

A sample of measuring angles with those included for 2-D...which my student
LOVED!!!!

Thanks!
