[Pibe-division] graphing

Tue Oct 18 13:49:48 UTC 2011

On the subject of graphing, I agree that 3-D is better but when the teachers are going quite quickly through the material a quick representation is better than nothing. I think if you want to make a good tactile graphic you KISS it (keep it simple, silly) and a lot of well meaning teachers, para's, braillists, and sometimes parents forget to feel what they make with out looking at it. If you drew it and still don't know what it feels like than forget it! 
Has it been mentioned to use rubber-bands and push pins on a small cork board. Two of my students do this on embossed graph paper. They can feel the impression of the holes on the negative side and use the stretched rubber band to draw a straight line for the teacher's benefit. My older students Hate Wikki's because they lose the graph if the wax gets hot as it often does in Louisiana. When I make graphs or graphics for notes I use hot glue for simple line drawing. It heats quick, dries quick, you can make different thicknesses, and even a few textures.

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.

A few ideas

    graphing

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.
