Divide students into pairs. Member A of each pair should be blindfolded, and Member B of the pair is not allowed to talk. (In this way, the pair is like Helen Keller and Anne Sullivan.) Write a task on the board that Member B has to try to get Member A to do, such as "sit down on a chair and clap hands." Member B of each pair must try to get Member A to understand what to do within thirty seconds, without talking at all. The two then switch places and repeat the activity with a different, more complex prompt, such as "Say 'hello.'" After the activity, discuss with students how it felt to be unable to hear or see the directions, as well as how it felt to try to give directions to someone else without being able to talk to them or show them what to do.
