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.
Bente

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?
