[blindkid] Fwd: [LCA] math question

Another point of view... I do like the BrailleNote for Math, Pre-algebra,
Algebra, Chemestry, Calculus...
My daughter Carolina is in high school. I believe that the Perkins Brailler
is a great tool to learn how to work out problems. Still as your kids move
over to middle school and high school I have found that the braillenote has
its advantages. Nemeth code is found in the textbooks in a less spaced out
way than in elementary, no longer is a full cell used to represent a blank.
Fractions are written in a single line form. The BrailleNote allows you to
write in the higher level one line format and you can insert as you solve
the problem. You can't do that in embossed paper. Our kids will need to pay
attention to special separators in this more compact format (Begin exponent,
end fraction, etc).
An apparent difficulty of the BrailleNote for math is that you can't see
what is written on screen or on print. This is because the Braillenote
interprets the Nemeth code as if it was Grade 2 Braille and it looks like
garbage. To that effect I found a work around. We embossed the Nemeth code
files from the BrailleNote via Bluetooth to a PC and then passed the files
to Braille 2000. The result is that you can actually print algebra or
fractions (Nemeth code) and see it in black print algebraic notation (like
teachers write it) and you as the parent can see what mistakes your kid is
doing with the code as soon as he writes it. Not having to have an expert
transcriber check the code.
I love the BrailleNote for Pre-algebra, chemistry, etc. (Nemeth code), for
it has many advantages. But for your little ones I always would recommend
for them to learn through elementary with the Perkins Brailler and don't
forget the abacus. They should be able to compute the same number of digits
and speed their sighted peers can do, that is add subtract, multiply, divide
with connected abacus for the additional digits and decimals.

Similar situation here-- the brailler works best for our soon-to-be 4th
grader. Kendra is as skilled a BrailleNote user as you will find, especially
for her age. She's quite good with an abacus. We've used things like the
math window product. They all have their uses, but so far, when it comes to
math, the braillewriter gives the best access to the entire math problem at
once. It is just hard to deal with large problems with access to only one
line at a time, and yes, the math window does solve this and work really
well as a learning tool, but in practice there are so many "fiddly bits"
that it doesn't seem to be usable to solve problems in much quantity.
