Nemeth code
Last updated
Nemeth code is the braille code used in the US for math and science notation, such as numbers, operation signs, fractions and equations.
Topic: Vision and hearing
In plain terms
Literary braille alone does not show math layouts clearly, so Nemeth code adds rules and symbols for mathematical expressions. Students learn it alongside literary braille, often starting in the early grades with numbers and simple operations. Many US programs use Unified English Braille for text and Nemeth code within it for math, following state and national guidance.
How it shows up in an IEP
Students who read braille need Nemeth instruction in time to keep up with grade-level math. Goals might target reading and writing specific notation, like fractions or exponents, with accuracy probes.
Example
A fourth grader who reads braille learns the Nemeth fraction indicators and solves 10 fraction problems on a braillewriter with 80% accuracy.
