Mathematics
Teaching Mathematics to students who are blind or visually impaired is imperative, as with all students. These students are fully capable of succeeding in advanced mathematics with the right materials, tools, and technology. These materials include the Nemeth Code and excellent tactile graphics. Tools and technology include everything from low tech to high tech. A collection of videos shares information on many of these topics.
