Louis Braille was born on this day in 1809. His invention is a writing system that allows blind and partially-sighted people to communicate, using patterns of raised dots that can be identified as letters by touch.
There are a number of opportunities to raise awareness of Braille in the maths classroom:
- There are a limited number of configurations of dots in a Braille cell. Can you work out how many?
- Can you describe the layout of dots in a Braille cell in words? (Promotes use of language such as ‘parallel’, ‘rows’ and ‘columns’.)
- Which letter in the Braille alphabet has the most lines of symmetry?

And here is a very engaging maths activity that use Braille to encourage mathematical thinking:
