Many assistive technology devices, both low-tech and mid-tech, have been created to assist learners with disabilities in completing their math work. These devices or items can include, but are definitely not limited to, rubber stamps, number lines, laminated addition and multiplication tables, and special rulers that can be used as transparent overlays in order to assist students with understanding the relationships between units of measurement (Dell, Newton, Petroff, 2012). Additional technologies that students with poor fine motor control, learning disabilities, and visual impairments can benefit from include large calculators with over-sized buttons, talking calculators that read aloud the buttons that are stroked, and "See N' Solve" calculators that show students an entire math problem on the screen.
