Math Accommodations
Accessing books/problem sets
Doing homework/tests
Getting information in class
Tips for Deaf and Hard
of Hearing Students
Suggestions for
Face the students
– Do not talk facing the board
Repeat student questions
– The deaf student may not have been looking at the
Make sure you can be seen clearly
– Do not stand and talk in front of a bright window
Use gestures
– Pointing to what you’re talking about is helpful
Build in pauses
– Deaf students do a lot of multi-tasking, allow some pauses
Tips for Students with
Upper Limb Impairments
Math equation programs allow
keyboard entry
– Scientific Notebook
– MathType (plug-in for Word)
MathTalk allows voice entry
– Requires MathTalk, Dragon
NaturallySpeaking and Scientific
Notebook (all three!)
http://www.mathtalk.com/ OR
Books On-screen
Scan to PDF
Read visually on-screen (no TTS)
Foot pedal mouse
Use Dragon to advance pages onscreen
Remove spine and rebind to lay flat
Use hardware page-turning systems
Tips for LD Students
Instructor side
– Concrete, specific descriptions
– Verbalize equations and operations
Student side
– Verbalize the process
– Have students explain patterns they see
Spread one semester courses over two
Teach strategies, not just algorithms
Tactile graphs
Color highlighting
Draw pictures
Work in quiet without clutter
Videotape students studying
– Students may be totally unaware of what
they are doing while studying—
videotaping provides feedback
Word Problems
Learn key words
“and,” “sum,” “increased” mean add
“take away,” “difference,” “less” mean subtract
“of,” “times” means multiply
“per,” “out of,” “ratio of,” “quotient” mean divide
Highlight what is important
– Look for key words
List information
Draw pictures
Auditory Math
Math books in MathML
– Create in MathType or Scientific Notebook
MathPlayer reads and highlights
– Free download from Design Science
– http://www.dessci.com/
Read&Write Gold, Dolphin Tutor, and WYNN
work with MathPlayer
– Kurzweil only works from the Web interface.
Please Note
Many LD students do not find hearing
problem sets helpful
HOWEVER, many LD students find
hearing word problems extremely

Tips for Blind Students
Be wary of assumptions
Blindness covers a range
– Most blind folks have some sight
– Many do see color
Not all blind people read Braille
– In fact, many CC students do not
Not all students who read Braille read
Nemeth math Braille
Nemeth Braille Example
– 1234567890
– x² + 2x + 2 = 10
– x^2"+2x+2 .k #10
Use Meaningful Words
Use concrete terms
– “Here is the equation.”
– “We start with the equation and factor.”
– “Set both factors equal to zero and solve
to get the result.”
– This, that, here, there, thing
In the following example,
you would say everything!
Don’t just write it; verbalize it! Say each step.
6x2 = 53x + 9
Subtract 53x and 9 from both sides
6x2 – 53x – 9 = 0
Trinomial factoring gives us
(6x + 1)(x – 9) = 0
Set both factors equal to zero
6x + 1 = 0 and x – 9 = 0
Solve each equation…etc.
Braille options
Brailling math is expensive and timeconsuming
– Algebra books can cost $25,000+
– Calculus books can cost $100,000+
Check books already in Braille and see if
instructor is willing to use the problem sets
Work with an instructor on “independent
study” with a book already in Braille
Lots of Math in Braille!
Alternate Text Production Center (ATPC)
– www.atpc.net
ATPC produces Braille and tactile graphics
free for the CCCs
– Sells books to those outside CCC system
Must have syllabus to begin project
– They braille only required chapters
– The more advance notice, the better

Nemeth on Campus
Scientific Notebook documents can be
translated into Nemeth math Braille
– www.mackichan.com
– From other equation editors, save as
– Take into Scientific Notebook and save
– Open with Duxbury Braille Translation
Software (www.duxsys.com)
Nemeth Back Translation
A student’s work in Nemeth will have
to be translated into a printable format
For hard-copy work, student will have
to read to a scribe
With an electronic braille notetaker,
can use Nemetex
– Nemeth to LaTeX conversion
