Oops I forgot. You can also send these straight to the Tiger - even faster and cheaper - once you've bought the Tiger. ----- Original Message ----- From: "Susan A Osterhaus" <osterhauss@xxxxxxxxx>

The reason that I don't like the nets at
http://www.korthalsaltes.com/index_hoofd2.html is that they have "tabs" on
them to facilitate taping faces together. This causes confusion for some
blind students, and requires extra folding work.

I prefer another source, but unfortunately there are not nearly as many
polyhedra represented.
http://www.harcourtschool.com/teacher_resources/math/grade_08/g8_nets.html

You can copy these onto swell paper, and the student or teacher can cut
around the outer perimeter. Then, the student just folds on the raised lines and folds the net into a 3-D model. This is easier than the alternative, but 
scotchtape doesn't like to stick as easily to these. A student could also
create and fold these independently.

Alternatively, you can copy these onto braille paper and have a sighted
teacher use a tracing wheel to go over all the black lines. Then, the
student just folds on the raised lines and folds the net into a 3-D model.
This is more work for the teacher, but the 3-D model is a little sturdier
than the swell paper model and scotchtape adheres better. Plus, this is a
less expensive method.

Lisa,
Here is an interesting one that contains free mats for just about every
polyhedron known to man. May not be that useful to you, or what you are
looking for, but definitely fascinating and worth a look!

Quote from the site:
"Polyhedra are beautiful 3-D geometrical figures that have fascinated
philosophers, mathematicians and artists for millennia. On this site are
a few hundred paper models available for free."

I have used a few for text book production, and teachers may find them
useful to knock up a quick model or two.

Hi,
I have been asked the following question -

"I was wondering if you knew of various web sites where people can
obtain (purchase or get for free) tactile diagrams suitable for swell >
/ capsule paper?"

Suggestions?

Thanks,
Lisa
