Hello. I admire your determination to Braille this very challenging material accurately. As a retired TVI, however, may I add a word of caution? Unless you are working closely with the teacher, how can you be sure that the concepts you identify are what she is actually teaching? I've always been told that a braillist is a braillist, not an editor and not a teacher. It can be a fine line, but one we do have to watch carefully.
