Sally,
You bring up a great point, hence the reason to make things 3-D as much as possible--somehow sighted people think that just outlining something makes if "viewable" for a blind student. 1-D Flat graphs and pictures are very hard to make out with fingers. I always tell my paras to close their eyes and if they can't figure it out, don't expect a student too.

>Sand paper can be used for making shaded
areas. There are a lot of different textures available.

>One thing I would mention, just because it is on my
mind, not everything that has a picture in a textbook needs to be made into a
tactile graphic. The braillists in our district who create the
graphics for my son have a love affair with puff paint. They use it to
draw replicas of the print pictures. Frequently the puff paint is sloppy
and/or done in a way that just couldn't make sense to a blind user. Try
as I might to convey to folks that creating tactile graphics requires a LOT
of higher level thinking, the braillists seem to think it is just drawing.
It makes me a little crazy. You would get a kick out of the DNA pictures
that came home last night. Only problem is that my son has a test on this
material today and the local people created the braille
test.

>>I use many things: I try to make everything 3-D that can be. Look at APH.org for so many math manipulatives ...there are many. Wikki sticks on paper are great also for making graphs. Go to fabric store and pick up stick backed material, dots and other sticky back items that are great for making graphs into 3-D. I also use the draftsman and students can draw their own pictures--Aph also offers a tactile kit which is wonderful too. Using a long slate n stylus so they can label the paper works perfectly.

>>>I am working with a student in algebra 2. She
is graphing inequalities so we need to create a dash line, a straight line
and shade the areas between the lines. We are having trouble reading
the graphs in the book and understanding where the area between the lines
are. I would appreciate any help.
