Jason is in 8th grade and is completing High School Algebra 1, no one in his
class is using graphing calculators yet. The IA makes braille paper into
graph paper using the Braille Writer to make the lines. Jason uses alligator
clips to clip the graph paper to cork, he marks the graph paper using small
push pins then uses dry spaghetti noodles to plot the lines. For a graph he
needs to look at for data the IA uses the same graph paper with Wikki Stixs
to make the bars then he has a written descritption for the data. I hope
this makes sense, I am not much involved in his math since he surpassed my
ablilities long ago. The technique must be working as he is a straight A
math student.

Interesting you say that, Mike. We made lots of
graphs for Serena to use for algebra I & II. She
did use them and plotted away. However, when she
took physics, she did all of it via math
formulae. I really don't know if one was more
meaningful to her than the other.

For graphing, we glued two pieces of string down
for the axes. String is good because it allows
the person to see the axis and the background at
the same time, thereby giving context. Then
Serena would plot the graph with bits and lines
of Wikki Stix. For the ones that needed shading,
we used aluminum foil. It was nice because when
you pressed it down over the graph paper, you
could still feel the graph lines, again giving
context, yet it felt different from the bare graph paper. Seemed to work
well.
