Braille Hundred Chart

Description
A 3D-printed braille hundred chart designed for students with visual impairments. Numbers 1 to 100 are displayed in Nemeth Code (lower-cell digits) across a 10×10 grid. The high-contrast layout — dark cells with raised white braille dots — supports both tactile reading for blind students and visual reading for those with low vision. Teachers, parents, and special education professionals can print this at home as a hands-on math manipulative.
