The student may need specific orientation training in relation to the school buildings and grounds.
Note that red, green and blue markers can be more difficult for the student to read when one is writing on the whiteboard.
Lighting should be adequate but without glare.
Windows should be behind the student, and the teacher should never teach from in front of the window.
Contrast with background should be considered when utilising print.
Consider using paper that is neither glossy nor glaring.
Students may need extra time to complete work. If doing repetitive work assign them fewer questions/problems than their peers. If using a manual signing system, ensure signs are accurate and consistent.
