Description
This is a board I made that can give access to math learners who are visually impaired. It's a coordinate plane slash geoboard. Use rubber bands to "graph" lines and investigate their intersections. The pegs are numbered from 0 to 4 in Braille. Raised numbers are positive; recessed numbers are negative.
