Correct option is A
To accommodate students with low vision, teachers should avoid providing visually cluttered notes as they can be difficult to read and understand. Providing magnifying glasses, large font textbooks, and tactile maps and diagrams are actually helpful accommodations for students with low vision. These aids make learning materials more accessible and cater to their specific visual needs. Therefore, the practice that should be avoided is giving visually cluttered notes, as they can exacerbate the difficulties faced by students with low vision.
