Telephone Game
See more: Learning Activities & Games
Do you know the "Telephone Game": one person whispers something to person 2, who whispers the same message to person 3, etc. etc. Then, the last person repeats the message out loud, for the whole group. Often: a totally different message!
OK, this is the same game, but in sign language. Everyone lines up or forms a circle without looking at each other. The first person taps person #2 on the shoulder and signs something to him or her. Then, person #2 signs the same (hopefully!) message to person #3, and so on.
Make sure that thee people further along in the line don't see! When the message gets to the last person: ask person #1 to sign the original message, then ask the last person to sign the message that s/he received at the end of the line. Same message? Or: totally different?
