Create a pair or two small groups. Find the corners that ‘communicate’ between each other and use the connection to say a phrase or a word to the other person/group. Be careful to not speak at the same time.
Write here your phrase/word, indicating also the name of the group/person to whom you address it.
Ex. To David: I wish I could eat your lunch.
Listen to the message said by the other group/person and write it here, indicating the speaker.
Ex. Yellow group: To be honest, our favourite colour is blue.
