I made this number line for one of my students with a cortical visual impairment (CVI). He is learning about number lines in his kindergarten class and we needed a more functional one that would be not only easy to visually fixate on, but also to manipulate.

You can adapt this to your student’s preferred color. It will also work for a low vision student and braille student. For low vision, make sure you use the contrast colors that work best for that specific student and for a braille student, ensure the lines are tactile and incorporate the braille numbers below.
