As a future teacher, I will surely have to deal with students who have special needs such as being blind or dyslexic. I believe that blind students still have the required abilities to perform well with languages. Maybe their sight is completely impaired, but they still have other senses.
There are many games that can be played simply using sound, or touch, or any other senses. We can also combine sesnses to create a fun game.
For example, students could play a matching game. They would hear a sound and they would have to identify which animal they hear. Or, you could give them objects in their hands and ask them to describe them as well as they can using the target language.
Blind people have very good auditory skills and we should take advantage of these when creating activities for them. There are thousands of ideas for cool games involving only sound.
