Slide-A-Round Math Manipulatives for Kids who are Blind or Visually Impaired
https://slidearoundmath.com/
Abstract math concepts such as understanding and comprehension of place value, simplifying and comparing fractions, and estimating and rounding of whole numbers and decimals are challenging for anyone. But to explain them to someone with vision loss, you might want to check out this tool. Slide-A-Round Math Manipulatives were created by Jim Franklin, an elementary special education teacher in Georgia who was looking for a tool to teach abstract math to his students.
The manipulatives feature movable, interchangeable slides, and are manufactured in the US of recycled plastic with steel reinforcement. It also folds up in a pretty nifty way, for easy storage. The site offers free downloadable worksheets on rounding numbers, money, decimals, elapsed time and more.
There are braille versions for those with visual impairment. For more information on this, including how to order, visit slidearoundmath.com .
