[Blindmath] graphing inequalities

[Louis Maher]

Yes; however, you do not need the plastic paper, normal paper from a tablet
or copier paper works equally as well.

This method is quick and painless.

Thanks Louis, isn't that similar to the mat that APH puts out on which you
can put plastic paper?

If i put raised line graph paper on the sensational blackboard will that
work? The student has to be able to use the graph paper as a reference point

Maureen,

You should  consider the "sensational Blackboard" available at
http://sensationalbooks.com/.
With this $30 item, a blind or sighted person can rapidly sketch a graph
using a ball-point pin and a plane piece of paper, and the blind individual
can feel the graph, and a sighted person can see the graph.

I Have a student who is going to have to graph inequalities. I am thinking
the best approach is to have her graph them using the APH graphic aid, push
pins for dotted lines, rubber bands for solid lines, and I am thinking that
to for the student to show the areas, I can have her use Wiki sticks in one
direction for one equation and wiki sticks in another direction for the
other.

In terms of her handing in this work  I have been showing her how to
photograph the graph, but this is not so fail safe. The graph is usually too
far away for the teacher to see the details, and the student has no idea if
the photo will make sense.

Any suggestions? No calculators permitted at this point. The second part of
this issue is convincing the classroom teacher that it will work!

problem is the misunderstanding and lack of education that exists.  If a
blind person has the proper training and opportunity, blindness can be
reduced to a mere physical nuisance."Kenneth Jernigan
