In developing open source textbooks and resources for college algebra and trigonometry courses, the greatest challenge has been making these materials available to students with disabilities. Salt Lake Community College has solved this problem through frequent ongoing meetings of a Math Accessibility Working Group, comprised of math faculty and disability resource experts. The presenters will share the plan developed through this group, along with its implementation. Several features, such as text reading and alt-tagging, will be demonstrated. Attendees are encouraged to ask questions. All textbooks and resources developed through this collaboration are available and will be shared with interested attendees.
