Math teacher working with students with visual impairments currently as an aide.

Any graphs that will come up will be helpful, though if the student has a book in braille, will likely have some graph examples, but perhaps a tactile graph that the student could plot points or graphs. Perhaps a tactile circle with discernable spots for any trigonometry that might show up.

Also this student very likely has a Teacher of the Visually Impaired (TVI) working with them that should be in charge of adapting materials. I would ask to speak to them and find out what materials would be best supplemental in this endeavor. I say this as I have had several projects to help our students in math just not go as planned as it was too busy and the studnet wouldn't get far without a lot of help from the TVI or an aide.

If the TVI is not available to help, due to time constraints, sit down with the student and go through the book. Ask the math teacher if they have a plan of what material will be covered, and go through the students braille books to see what might be challenging. Sometimes the visuals are reduced to just usable lines that gets rid of the clutter and so the student can get the core issue the problem presents and nothing should have to be printed.
