2. History of Braille Developed by Louis Braille

3. Braille Overview
Uncontracted (formerly Grade One) Braille consists of the 26-letter alphabet, numbers, and punctuation.
Contracted (formerly Grade Two) Braille adds 189 contractions and short-form words.

4. Braille Cell
All Braille characters are based on six dots called a Braille cell.

5. A through J
The first 10 letters of the alphabet are made using the top four dots in the Braille cell (dots ).

6. K through T
The next 10 letters of the alphabet are made by adding dot three to the first 10 letters.

7. U through Z
The last six letters of the alphabet are created by adding dot 6.
What happened to “W”? It was added later and does not quite fit the pattern.

9. That’s nice, but…
How do we remember the alphabet?

10. Braille and Print
You already know the print alphabet, and the Braille letters look like the print letters.
Let’s connect the dots!

13. Numbers
Braille uses a special sign (dots ) to show that what follows is a number.
Logically, this sign is called…the number sign!

14. Letters to Numbers
Braille uses the first 10 letters of the alphabet, preceded by the number sign, to stand for the single-digit numbers.
“a” is 1, “b” is 2, “c” is 3, etc. through “j,” which is 0

15. Numbers in Literary Braille
3 = #c
4 = #d
5 = #e
6 = #f
7 = #g
8 = #h
9 = #i
0 = #j

16. Multidigit Numbers
12 = #ab
25 = #be
30 = #cj
46 = #df
51 = #ea
63 = #fc
74 = #gd
87 = #hg
