[Blindmath] graphing inequalities feedback

Fri Nov 8 03:46:21 UTC 2013

I haven't been very responsive because I'm just finishing up a week with
students doing math all day long.  I teach this short-term programs' class
once a year - mainly aimed at beginning Algebra I students We are having
an awful lot of fun creating all kinds of tactile graphics.  We've already
created number line graphs; points, figures, and linear equations and
inequalities on the coordinate plane; Venn diagrams; various angles; and
various nets and 3D models using Geometro polygons. We have also worked
with the Orion TI-36X talking scientific calculator, and today we were
immersed in the new Orion TI-84+ talking graphing calculator and a little
review on the Audio Graphing Calculator (AGC).

One way to keep track of which pictures of student graphs go with which
problem is something we devised. Purchase a set of index cards on a
spiral. Each index card can be labeled with a large print number (for the
math teacher) and a Nemeth number corresponding to a "math problem"
number. So, the student graphs the answer to problem 12, flips the index
cards to #12, and places that in a corner of the graph board. If the
student is producing tactile graphics from the AGC to a Tiger, he/she can
just insert the problem number in the title space when printing/embossing
to the Tiger or copying onto PIAF paper. The new Orion TI-84+ allows you
to create a screen print of the graphic by cabling to a laptop and then to
the Tiger; however, soon we should be able to print directly from the
Orion to the Tiger. We'll need to devise a new method for keeping track of
which graph goes with which problem. Perhaps the APH Nemeth feel and peel
numbers?

Subject: [Blindmath] graphing inequalities feedback

I am a parent of a junior in high school who is taking an Integrated Math
Curriculum.  He is on level and has done fine with his high school Math -
but has struggled some with his Geometry.  I have been reading all of the
graphing answers and think most of them would work - depending on what the
teacher is looking for.  I think that is the key here and somewhere in the
original post you indicated is that you would need to get the teacher's
buy in.

My son did a graphing Inequality Math 3 unit earlier this fall and he does
have some usable vision in 1 eye (corrects to around 20/250) so he can use
large print.  He has not had to use tactile graphics except in Geometry
where it is most helpful.  Even though he has the ability to see, he still
does most of his graphing nonvisually.  For instance when determining if a
graph is going to shrink or stretch he can tell by looking at the
coefficients.  With the inequalities - unless the standard is to look at
the reproduce the answer on the graph - he will do it nonvisually also as
most tests these days are multiple choice.  Depending on whether the
answers are positive or negative he knows how to shade them or describe
how they should be shaded.

Even when they are testing the standard that the student calculate and
produce the graph himself, it will probably be on a multiple choice test
where they will be given 4 graphs to look at and then choose the answer
that best represents the answer.  I agree with one of the first responders
who said that learning how to do it nonvisually as much as possible will
help - at least at first.  Also, determining what the standard is and how
it is going to be tested and what the teacher is going to accept as an
answer is really what you need to know to drive the problem of how the
student is going to create the graphs in both classwork (where they are
learning the
concept) And classroom testing (where it will be tested).

I also agree that taking pictures of the graph is cumbersome and difficult
for both the student to keep track of and then for the teacher to make
sense of as a typical homework assignment may have 20 or 30 problems so
you may have 20-30 pictures to correlate graphing pictures to - for
several weeks.
Most high schools allow calculators - but in this case - even with
emulation software you would have the tracking of the answers issue to
deal with.  So
- really to answer your question you need to determine from the teacher
how much of the standard is the student creating the graph himself verses
him knowing how to interpret the graph.  He will probably be tested on
both - but it may help you know how to focus your effort.

I have learned over my son's high school years that some of the tasks that
are tested with my son's Math education are so cumbersome and difficult to
have him do - it detracts from the larger Math concept he is learning and
in that case - I am okay with him not being as adept at creating a graph
and as he is at interpreting it.  That is a difficult call to make - only
the teacher and student can do it.  For instance, I was concerned when the
concept of triangles was first being introduced about him visually
discerning the Incenters, Outcenters ect.  It quickly became clear to me
on his test that if it was a conceptual question asking what type of
triangle had which characteristic he got it.  When he had to look at it,
he did not - that is why we started tactile graphics.

However, he still conceptually understood the triangles and this helped
going into Math for his Sophomore and Junior Year.  Conics are about to
become his Math world and already they are talking about which standards
he needs to able to do in what way.  You student sounds like he is in
middle school because of the fact that they are not allowing him to use
calculators.  What helped my son the most last year was when he started
printing the Math standards and discussing them with his teacher.

By him opening the dialog - the teacher bought in more that certain areas
might be more difficult for him to learn.  That is what I would recommend
here - take the graphing standards and have the student, you and the
teacher sit down together and see how much they really have to be able to
create and how much they need to understand and I am hoping the teacher
will jump on board and figure it out with you.

Hi, I am a first year theoretical physics student, one of the first term
modules includes a worksheet on wolfram alpha but I can't seem to make it
work with jaws. I find the links and text that are apparently close to the
answer text, but jaws won't read the answer itself.
Does any-one know if wolfram alpha is accessable? If not, what would you
recommend for an unexperienced computer user with jaws?
Sage has been recommended but uses a virtual machine to run Linux which I
have never used before, is the Lenux environment first-time-user-friendly?
Thank you

In my work as a TVI we produced a grid with axis.  I then had my student
locate intercepts and press the grid down I those intersections so he
could find them.  He would then place a ruler or straight edge on the two
depressions and draw the appropriate line (solid or dashed). Then without
removing the ruler would use it as a guide to 'shade' the region.

The dilemma with this mood is that the student is purely learning how to
'produce' a product useful for the sighted.  Which is anti-thetical to all
graphing for learning math.  The graph is meant to be a tool for
interpretation and connection.  Since the answer is a region a table or
list of data points isn't very useful either.

A puff pun would at least make something more useful.  If the student were
particularly savvy they could pin or stylus the points and then do the
shading and drawing of the line by flipping the paper and using the
reference marks.  But again we are creating a lot more work than the
sighted peer to create a tool that is less useful.

In the light side most sighted kids perform poorly in the concept area of
hush is task.  At least in my experience as a math teacher...

This will put a smile on Sue O's face, who is on this list I believe. The
series of videos is a great on, thanks Sue! I was able to send it to the
math teacher. Since it came from another,math teacher, it was well
received.

We live in a visual world, so I know my students will always have to prove
they know what they understand in visual formats, or at least will most
often have to. At least the graphic aid from APH allows them to plot
points and lines in a similar way to the sighted peers.

Thanks, all!

Maureen,

If your student doesn't have the money to purchase this or needs something
more portable there is another option.  I took a piece of braille graph
paper that had the 4 quadrants and taped it around the edges on to a cork
tile that I got at an office supply place.  I was able to give the
students pins and yarn and rubber bands and they had a portable graphing
board that they could stick in their backpack and take to class.  When the
braille paper got too many holes in it from use, we just taped on a new
piece.
Going back to your inequality question you could use yarn between pins for
the solid lines and a series of pins for the dashed lines.  They could use
the yarn at first as a guide to make sure the pins are placed correctly
and then remove the yarn.

Thanks Bente! I like your portable idea. The graphic aide is indeed big!

Maureen,

If your student doesn't have the money to purchase this or needs something
more portable there is another option.  I took a piece of braille graph
paper that had the 4 quadrants and taped it around the edges on to a cork
tile that I got at an office supply place.  I was able to give the
students pins and yarn and rubber bands and they had a portable graphing
board that they could stick in their backpack and take to class.  When the
braille paper got too many holes in it from use, we just taped on a new
piece.
Going back to your inequality question you could use yarn between pins for
the solid lines and a series of pins for the dashed lines.  They could use
the yarn at first as a guide to make sure the pins are placed correctly
and then remove the yarn.

This will put a smile on Sue O's face, who is on this list I believe. The
series of videos is a great on, thanks Sue! I was able to send it to the
math teacher. Since it came from another,math teacher, it was well
received.

We live in a visual world, so I know my students will always have to prove
they know what they understand in visual formats, or at least will most
often have to. At least the graphic aid from APH allows them to plot
points and lines in a similar way to the sighted peers.

Thanks, all!

HEY,

Can you guys tell me where I an get Braille Graph Paper??!!??
I am GOING to need some!
OMG!! WHO KNEW!
I'd like vendor and/or item # if possible

Also, are there good how-to's on using what my district calls "Patty
Paper" or semi-transparent wax paper for doing geometric constructions?
Are there other / better blind ways to do constructions?

Ian
