What do the numbers mean in a braille cell?
The dot positions in the braille cell are represented by a number 1-6 as shown in the image above. The numbers correspond to the keys of a braille writer used to produce the embossed material. If a braille cell has more than one raised dot, each key on the braille writer must be held down at the same time to produce the correct braille cell.
What can I use to teach Braille to blind students?
There are many strategies teachers have used to teach the spatial position and dot numbers of specific dots in the braille cell. One of the most widely used method is using a muffin tin with tennis balls. Half dozen egg cartons can also be used or you can find an egg/shape match game.
What is the basis of the Braille system?
The basis of the various braille codes for the world’s natural languages is a straightforward assignment of most of the dot patterns to letters of the alphabet, punctuation marks and other symbols.
