Accessible Graphing Calculators
Recently we searched for a graphing calculator (such as the TI-83/84/89) that has large keys...the bad news (and ideas for dealing with the issue) comes from CATEA, the Center for Assistive Technology and Environmental Access (http://www.catea.org/quickrefguides/guides/Calculators.php):
This is a highly sought product that, unfortunately, is not yet available. The only current option is to use a computer-based program that emulates the calculator, along with an appropriate keyboard. Computer software options include:- TI InterActive! is a software version of the TI-83 graphing calculator. It is available from Texas Instruments for about $50.
- The Larsen Interactive Pre-calculus CD ROM series includes tutorials for algebra, college algebra, trigonometry and pre-calculus. All CD-ROM's have a built-in graphing calculator with TI82 or TI83 functions as part of the package. It is available from Houghton Mifflin Company.
Is there a way that I could feel a graph?
Products exist that convert mathematical data and forms to tactile form. The following are a few examples.
Geometry Tactile Graphics Kit is a set of raised line drawings depicting concepts, figures, and relationships covered in geometry texts. The drawings are embossed in thermoform plastic, and are available from American Printing House for the Blind.
Generate a graph on a scientific graphing calculator program such as Graph-It, then emboss an image of the graph using a braille embosser.

Hi! The difficulty with these items is that students are not allowed to utilize them during SOL testing so, even if they are able to demonstrate knowledge of a particular skill in class, they may still not get a "verified credit" for the course. Ugh!
