[Blindmath] graphing inequalities

Suggestion about the plastic paper. First I can order it for my students, and they like it for some things. If I run out of that I use paper protector sleeves, which you can but at Staples. I cut them open, and voila have one large one, or I can cut it and have two!

Li,

Forget the plastic film.  It does not come with gridlines, and the plastic
is expensive.

Use plain paper.

If the plastic films/paper used with Draftsman come in with raised grid
lines, with that help?

Thanks,

Li

Maureen,

The graph paper would not work for the student because the student
cannot feel the graph paper, unless you sketched a few of the lines in
the graph paper grid.

In this case, you need only show the concept of the graph.  You do not
have to have accuracy, just the general shape.

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!
