Nemeth Online Tutorial from TSBVI

A free online tutorial on the Nemeth Code is now available from Texas School for the Blind and Visually Impaired (TSBVI). Nemeth Code is used for braille math and science notations.

A FREE Nemeth online resource is now available for Pre-K through 8th grade levels on the TSBVI Online Learning webpage!  It is designed to provide easy access to support learning or reinforcing Nemeth braille code skills for families, teachers or paraeducators working with students who are braille readers.

These modules are a companion to the TSBVI publication, Nemeth at a Glance. Dr. Derrick Smith, professor at the University of Alabama in Huntsville, was the creator of this series, with sections by Janet Bean, Lead Teacher in the TSBVI Curriculum Department.

Although presented in the grade level order that symbols are typically introduced to students in school, you can dip in at any level to find specific symbols and examples.

Modules include an explanation of the symbol, relevant rules, and examples of how to use the symbol in math examples. There are multiple samples of using Nemeth within UEB contexts.  Short, ungraded quizzes following each module will help document mastery of the material and provide useful feedback.  Completing these optional quizzes will lead to a certification of completion.
