[Blindmath] Creating graph and charts

Wed Feb 29 16:48:35 UTC 2012

Hi Maureen,

The APH Graphic Aid for Mathematics (rubber graph board) is still my
favorite tool for graphing manually, and it can be used for many years -
even at the college level! I have several YouTube videos on using the APH
Graph Board and other math tools and technology. You can access these in an
organized fashion by going to:
http://distance.tsbvi.edu/osterhaus_math_intro.html  However, at the present
time, you will find the videos outlined below. By the way, I teach my
students (Yes, they are blind!) how to take their own digital photos of
their graphs, but I allow parents and siblings to join in the fun if they
REALLY want to help. Very little labeling is done. However, index cards on a
small binder can be brailled and printed with large numbers (and letters if
need be) for identifying each problem number. So your student could
independently flip the tiny "flipchart" to the correct problem number and
place it in the corner of the graph board that is hopefully clear of data.
This way he has "labeled" each graph to match each homework problem. As your
student gets older, I'm sure they will come up with all kinds of
modifications on their own. The math teacher may have some suggestions as
well.

I have created some other videos, but apparently my media person has not yet
downloaded them to YouTube, so he and I will be getting together tomorrow to
go through his computer and find more videos for your viewing "pleasure" or
not. <grin>

I'm not as crazy about geoboards. They are definitely less expensive than
other items on the commercial market, but the APH Graphic Aid for
Mathematics is available on federal quota monies if you live in the United
States and meet certain student restrictions. So, it is essentially free of
cost.

Although your student is still a bit young for the AGC, I would recommend
that they start using an Orion TI-36X talking scientific calculator
(non-graphing) when the math teacher is ready for the entire class to start
using calculators. Hopefully your student is already proficient on the
abacus. If so, or even if not, be sure they know how to prime factor on the
abacus - very easy really. One of my students in my week-long intensive
short term program class on math tools and technology remarked that his
favorite two tools for the week were the abacus for prime factoring and the
AGC. That shows that there is a place for both low tech and high tech.

I'm also attaching a suggested adaptive tools and materials list that should
assist your student from now through high school and possibly even into
college.

Best wishes,
Susan

Oh, my goodness. I read all the way to the end wondering how she was going
to travel back and forth on the bus with the graphic aide, then I read that
you take a photo....that is ingenious!

How does the student label the charts?

Has anyone tried this?
The Accessible Graphing Calculator (AGC) From ViewPlus Software? Too much
too soon for an advanced math student in middle school?

Yes! The student I work with (an 8th grader) uses the Graphic Aid for
Mathematics from APH (1-00-460-01). We use a combination of differently
shaped push pins (to represent different data) and rubber bands of different
lenghts.  When necessary we also use rubber bands to create the X/Y axis.
She keeps one at school and one at home. For homework, her parents take a
picture of her graphs and she attaches them to her homework.
Let me know if you have any more questions.
