TEACHING MATH TO VISUALLY IMPAIRED STUDENTS  Susan Osterhaus
http://www.tsbvi.edu/math/
Questions and answers offering teaching strategies for
improving the mathematical understanding of visually impaired
students. Particular challenges addressed are:
 solving quadratic equations
 geometric constructions
 transformations, line symmetry, and tessellations
 linear measure, perimeter, and area
Other topics include math education and Nemeth, the American
math and science braille code; tactile math graphics
(graphs); the abacus, calculators, and other math tools; and
math resources such as publications, vendors, and people and
places. You may also download a computerized Nemeth Code
