At my school we developed a track for math for students with disability for whom the traditional math courses are inappropriate. Many of the topics and concepts from the traditional courses are addressed but in a practical or applied approach, with the principles of UDL incorporated. This is not a typical dumping ground situation that many of us have encountered. These are courses for students who need support in being independent and who will not benefit from being exposed to simplifying math like (5x + 2y – 3xy) – (7x – 8y + 9xy). Here is a link to some documents, including the units and topics.
