Hi J
Thanks for the advice. The link to Susan Osterhaus advice was very good .
Will keep you informed.
Best,

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.

J :)

Hi Saroj, Thank you very much for sending the .pdf of the document. Have you used this technique? Any thoughts about it? Thanks.
