[Pibe-division] Questions for 4th grade math

[Cindy Robinson]

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.
Thanks for your help!
