[BlindMath] Geometry help

Sat Feb 18 12:28:35 UTC 2023

I teach geometry to students who are visually impaired.  Great suggestions
already.  Below is a list of tools I use:

APH Mathbuilders Unit 6 (Aph.org)
APH Graphic Aid for Mathematics
3-dimensional figures more complex ones)
APH Draftsman (already mentioned)
Wiki Stix (already mentioned )
Geometro figures (some are in the Unit 6 kit)
Pre-made tactile diagrams  as needed
Braille geometry book to use diagrams (I have an old one I could give
you-in about 10 boxes-Holt from maybe 2006)

I follow/use a textbook, but I know many schools do not which makes
learning math difficult unless the student receives the lessons in a timely
manner and examples.

There is a Velcro board and Velcro “lines” in the APH Unit 6 kit.  I use
that to quickly throw together parallel lines (or not)  cut by a
transversal to teach all the kinds of angles formed. It works well.

I hope this helps.  I did not mention computer generated graphics because
it’s already on here.
Sincerely,
Maylene Bird
