Braille Mathematics Standards

Braille Mathematics Standards (2006)
California Department of Education  

The Braille Mathematics Standards are aligned with the California content standards for students who use print, but provide additional technical information pertaining to braille learners, including the mechanics of reading and setting up braille math problems, use of braille math symbols, use of the abacus as a calculation tool, and use of tactile graphing devices.  This 88-page document covers preschool through 12th grade and features resources and a glossary.
