I have not used the method with wax paper, though it sounds interesting for the 
more visually functional vi student.? That line on wax paper is white on white 
and would not be much better.? It does not, however, sound like it was written 
to work with vi students.? 

We were trying to do paper folding several years ago in 7th grade math.? My 
first year as a TVI and I've never even seen paper folding other than origami 
and I found that frustrating.? A gotta tell you, trial and error works, too. A 
quick warning that if
you are using folding sources from a print book for non-vi students,
enlargement won't work.? For some reason it is disproportionate to the
original and never folds correctly.? A better idea is to use the original paper 
model (maybe with 20/20 lines rewritten) and also a completed paper model so 
that the student knows what the object is supposed to look like.? You can't 
assume that a student knows what anything looks like in its entirety.? I used 
braille paper and the whole class ended up using braille paper---works pretty 
well and we had a lot of fun learning math.? I have never needed to do paper 
folding again, however we did do tessellations last year and that was 
challenging.? If I had to do paper folding again, I would research the tsbvi 
website.


Susan Osterhaus has some very interesting techniques for manipulation and 
mentions paper folding.
http://www.tsbvi.edu/math/teaching.htm
entitled Transformations.? In this section, I thought it very interesting that 
the folds could be labeled with corresponding points of reference for the vi 
student.? There was a little confusion because the object is sometimes upside 
down, but the braille student could have a braille letter with an indicator so 
that when the object is manipulated it won't change the letter.? The 
non-braille student could still have a tactile indicator made from the APH 
graphics kit---like a triangle or a circle that when upside down would not 
change.

Good luck.? Let us know what you did, too.? It could help the next TVI.
