omissions in spatial fractions

[Fred Van Ackeren]

Hi Kyle,

A math book on fractions shows fractions with omissions. I interpret spatial examples to be "for teaching purposes" and have inserted the underscore in place of blanks, squares and question marks.

I've attached the following: I couldn't upload the braille file so I put the info in a Word doc (braille may not be aligned properly).

pages 364, 370, 371, braille pages in word.

ALSO: I'm not sure about formatting the spatial material: operation signs, dividing lines in fractions, etc. If you could have a look I would appreciate it (and any other that I may have missed).

thanks, Fred

Kyle, sorry for the extra copies uploaded; I didn't see attachments when I edited so I re-attached; couldn't figure out how to delete them. Fred

Thank you for sharing this question and these examples, Fred.

I can certainly understand why you are interpreting some of the fractions in your examples to be spatial and "for teaching purposes." Being able to read a series of denominators across a single line, for instance, makes excellent instructional sense.

It looks like you have placed symbols of operation and comparison on the same braille line as a spatial fraction's horizontal line. I tend to agree with that placement, with the note that I am not 100% sure about having the minus symbol (and by extension any other operation symbol) UNspaced from the horizontal line of a spatial fraction.

Let me gather thoughts from the other members of this UEB Tech committee and get back with you.

Good morning Kyle,

I contacted the agency with the same questions and got this response:

-----------

I have a Summary of Advice for UEB Technical handout and Spatial Problems Rules and Advice slideshow that was given by Kyle DeJute (National Braille Association UEB Technical Committee) at a conference. This is what is on one of the slides: "As a guiding principle, if print alignment can be reasonably reproduced in braille, then follow print for the sign used to indicate omission. If print alignment cannot be reasonably reproduced in braille, use a visible space for each printed object that indicates omission."

I think because of this advice that I would use a question mark, a square or blue box (example: dots 4,5,6; 1,2,4,6; 3,4,5,6; 1,4,5) if it fits. If not, I would use the visible space symbol (dots 3,4,6). I like how you did the question marks!

Thanks!

I'm checking with you to see if this method is still valid.

thanks, Fred

[kdejute]

Yes, that method is still valid. 👍

It is not the only right way. But it can be a practical solution.

Braille on!
