A braille teaching device presents a planar base with opposed writing and reading surfaces. A plurality of cells in the base comprises an array of six bores corresponding to the location of potential embossed dots in the braille matrix. Dowels in each bore have writing and reading ends. To simulate the writing of a braille character selected dowels in each cell are plunged through the bores until the writing end of each dowel is positioned flush with the writing surface. Upon presenting the reading surface to the user, the user can read the previously written braille character by tactilely sensing the reading ends of each previously plunged dowel as displaced from the reading surface.
