Nemeth rules about basic shapes are in Rule 17.1.
The circle shape symbol in Nemeth is 1246, 14 which is illustrated in Example 17-2. (1246 is the shape indicator and 14 is the letter c for circle)
When a shape is filled in or shaded, an indicator is placed right after the (1246) shape symbol:
The filled-in indicator is 456
The shaded indicator is 46A filled-in ellipse and a shaded ellipse are illustrated in Examples 17-9 and 17-10. For a circle, the letter c (14) will be used instead of the letter e (15) for ellipse.
Whether a shape is shaded or filled in is a judgment call on your part. The two indicators allow for three different representations of a shape. In other words, "filled in" could be a color, "shaded" could be polka dots. If you feel your reader needs to know what the different circles look like in print, a transcriber's note can explain.
Proportional spacing is important to maintain. To show a point halfway between, ideally the lead line should be drawn as a tactile. Simple pin pricks on the back of the page are quick and easy, but if this is meant for production then I understand the temptation to use (456) instead. If you do this, it must be identified in a transcriber's note as a lead line, otherwise it looks like a math symbol.
If you will be using (456) as the lead line you will need to put three (2356)s between each tick mark in order to align halfway between the whole numbers. Start the number line at -3 and end it at 4 which allows room for the x label. (GSTG 6.5.1.10, third bullet, says you can omit unused portions of the line in order to accommodate a long number line.) If you feel the student needs to know that the print number line goes from -5 to 5 you can say so in a transcriber's note.
It's not clear to me whether the 5/2 point requires a (123456) above the number line. The blue markings seem to be arrowheads. It seems to me that it is simply pointing to the halfway spot on the number line, which is labeled below with the fraction.
Other things to fix in your transcription:
--There is no tick mark at the 5/2 point on the number line; do not use one in braille.
--The letter x should be included at the right end of the number line.
--Delete the errant symbol in the numerator (the first (34) symbol).
--I believe the fraction can be on line 10 unless that means the vertical line is too short. (GSTG 6.5.1.10, fifth bullet)
I hope this helps clarify the issues. If you think I have misled you, please let me know.

The box method does lend itself well to a modified table. I would align everything to the left. See attached brf.
I think the lattice method would be most clear as a tactile diagram. I would use thinner lines for the diagonals. It will be pretty big if you include numeric indicators. See what you think about not using NIs. But those little 1's in the corners will be a challenge. I don't really understand the lattice method. Are there hints to how it is read?
The stick method looks to me like something that would be done with actual sticks. I am not a TG expert, so I can't make suggestions here but it seems to me that it would be pretty confusing as a tactile graphic. I know you are good at that, so I am leaving it in your hands, Julie. My best suggestion is to follow print as best you can and describe the colors in a transcriber's note.
This looks like a very interesting project.

Hi Julie.
I am not aware of these methods. If you can send an image later, we can brainstorm approaches.

The definition of "exercise set" appears in the 2024 Update to Braille Formats which is why there is no reference to it in the 2022 Nemeth code book. We follow this Braille Formats pagination guideline in a Nemeth transcription.
Braille Formats defines "exercise set" as follows: Directions, examples, questions, and answer choices.
In a Nemeth transcription, directions translate to Nemeth instructions. There are no instructions preceding the itemized homework problems in your file. This is a simple vertical list and should follow the Braille Formats pagination directives given in BF Section 8.3.
What an interesting puzzle.
I would place each identifier on the same line as the top line of the problem. Then I would simply follow print alignment, using appropriate Nemeth spacing rules:
The logical sum symbol is an operation symbol so it is unspaced. NC 20.5
The tilde meaning "not" is also an operation symbol so it is unspaced. NC 20.9
The therefore symbol should be spaced. NC 23.18I think the word "invalid" reads better if it is put on the same line as each 'therefore' answer. Use the single-word switch.
Please note, if you are using the Nemeth lesson manual as a resource, the first edition is obsolete. The second edition is available for downloading at https://nfb.org/programs-services/braille-certification/mathematics-braille-transcribing

The highlighted paragraph is a subparagraph to the Example 3 sentence. Since you put the example in 3-5, the subparagraph should be in 7-5. There should not be a blank line between the two.

Hi Shellee.
As with any typeform, the surrounding text will give you a clue. If there is no context from which to determine an answer to your question, either bold or barred will give the reader the same information. As I research the use of the bold vs. the barred letter Z in mapping notation, I find that either is used. In this case, the typeform itself bears no specific or unique mathematical meaning.

Hi. Sorry for the delay. I am having trouble contacting the folks who wrote the Graphing Calculator Guidelines. If the answer is affecting your work, I would go ahead and follow established Nemeth rules regarding the English-letter indicator.

Hi Rodney.
I would not use this method for a second grade reader. I would borrow the method used for labeled chemistry arrows shown in Section 3.1.2.a of that code book. It's more graphic and follows print layout so a sighted helper is more likely to understand the braille.
See the attached brf file which illustrates this nice layout. Be sure to insert a blank line before *and after these constructions.
I also suggest using the general omission symbol for the omissions above the arrows. You can explain this layout and the substitution in the teacher notes that accompany your transcription.
Lindy
I understand your question and I agree with you that these letters do not qualify as "single letters" according to Nemeth Rule 6.3.1. Since I was not on the committee who wrote the Graphing Calculator Guidelines, I would like to check with them to be sure I have not missed something in those rules. I'll get back to you ...

Hi Susan.
These look like fun. I like your solution.
A couple of observations:
There's no need to show the words as bold unless there is significance to the typeform.
You can place the opening Nemeth Code indicator on the same line as the closing transcriber's note indicator.
Punctuate the words and the keyed abbreviations with a literary comma.
Make sure all your numbers are Nemeth numbers in the lower part of the cell. (There is a 1 and a 5 that need fixing)
I would move the problem to the left so the first cell of the separation line is in cell 1. This will give you more room for the comments.Lindy
