>> Susan Osterhaus: Okay, today we're going
to be talking about a compass.
And I'm going to go ahead and show you a --
one that's called a Staedtler compass,
but you should have seen something like this before.
And it's -- it's -- basically it has two arms that are connected
at the top, one of them is usually a pointed end,
and one has a pencil in it.
Now if I try to draw something with this particular compass --
well this particular one,
actually that pencil's not working very well.
Let me grab another one here.
And what I want to show you really is
that it does have a second arm
that I mean you can put something on.
So I've just put another pencil that's going to work for me,
and we can draw circles.
That's the main purpose of a compass,
to draw circles or arcs.
And you have a -- a radius, whatever this length is,
that would be the radius of your circle.
Now if you're looking at this and you're thinking in terms
of a low vision student, I -- I'm --
you probably can see this quite well with a camera,
but most students would like to use something other
than a pencil.
What's nice about a Staedtler or any compass, what you want is
to be able to pull this particular item either off,
or be able to insert a larger tool.
So this is the thing that I'm the most interested in.
If we put this in, what I'm --
hopefully you can notice is it's got a large opening here.
So you can put maybe something like a ball point pen.
When I was growing up, everything you had were --
all we had were these little cheap ones
that you just put a pencil in, and now this --
this is large enough that you can have a pen.
So let's see how this might look.
Is this going to look any -- any better?
Well it might be a little darker, but that's still --
that's still looking very much like the pencil.
Now -- so you might want to go
with something even a little lighter.
But now let's see if this will go in.
I don't think this will, so I'm going to -- I'm going to try it,
but I'm -- I'm thinking --
you'll notice that this is a little too wide.
So this is -- this is -- this is a good size --
wonder if I can get that to where you can see
that whole again -- but it's not large enough for this Sharpie.
What you're looking for for your student is some type of compass
that has some type of adaptation that it will take the pen
that your student prefers.
So what we're going to do is go to another compass,
which is called a Fiskars compass.
Now this particular one has a pointed end, but I'm going
to point out that this is a rubber tip instead
of a very, very stabby.
You'll notice otherwise I'd be going ouch, ouch.
This is rubber-tipped, and this one is a little safer
in the school system, and I think you can take this
on an airplane with you.
So what we're going to do -- try there is we can go ahead and put
that ball point pen in, so the ball point pen fits.
Let me tighten it up.
Oops got to hold onto that.
But again, that's not very, very good width there
for our low vision students.
So I'm going to go ahead and try that Sharpie and see
if it will fit in there.
Let me see if I can -- make sure
that you can see how -- why that is.
Okay. So this Sharpie should go right in there, and let's see
if that will fit, if this one's going to --
okay, this one's going to open up wide enough, and you're going
to be able to put that Sharpie in there.
So this might be something that your low vision student prefers.
It's getting a little -- it's getting a little thicker line.
But some of you may say well that's still not thick enough
for my particular student.
And again, what you want to do is find a compass
that fits your student's favorite pen.
Now here's an even wider Sharpie,
and for sure this one -- if the smaller one --
the thinner one wouldn't fit into this Staedtler compass,
this certainly wouldn't fit.
But let's try the Fiskars.
Again, I'm going to try to show you how wide --
or how large a diameter that is.
So we're going to slide this wider Sharpie in.
Now some students won't like a Sharpie, they --
they may prefer 20/20 or something else, but we're going
to show you this with a little bit wider Sharpie.
And let's see what we think about that.
Ah, okay so now we're getting -- we're getting even --
we're getting thicker yet --
