Low to mid tech for students with disabilities

Students with disabilities do not understand math or other topics in the same way or process as students without disabilities.  There is assistive technology for all content areas, but they differ based on skills and levels.  There are oversized calculators for students with visual impairments.  The numbers are bigger and easier to see.  The pads are bigger as well for those with those with physical impairments.  There are number flash cards, coin counters, and applications as well that can be used.  Below are examples of some of the assistive technology for math.  These could be used in groups or in one on one math practices.  I can see using these in my classroom if I taught younger students.
