Modeling after the scientist, Geerat Vermeij, who was also blind, I
taught my students to use a modified caliper.
To modify it, you just take the front glass off it. Use the dial caliper
by Helios.
Geerat used his caliper to measure objects of all different shapes. He
wrote the book, Privileged Hands. It is a VERY good instrument to teach
the students how to use.

Hi!
As part of our 4th grade math curriculum, our students need to use
rulers that go down to 16ths of an inch AND perpetual calendars.  Does
anyone know where we can locate Braille versions of these?
We and our TVI have not been able to find anything.  We tried to
make a ruler, but with no success.  When we tried to type in the
perpetual calendar to emboss it, it got all garbled and unusable.
Although I am sure it could be sorted out, it would be very
time-consuming.  We are hoping that someone knows where we can purchase
one.
