Yesterday at the end of my class the students were very tired and I decided to apply a very amusing activity to make them relax and laugh a little bit. It was a writing exercise called "one word story". Each student had a piece of paper and they were supposed to write one word each time and pass the sheet to the colleague on their right (or left) successively in order to create the story.
E.g. Student A: John
Student B: went
Student C: to
Student A: Africa...
They had to keep in mind the structures of sentences and also use verbs in past simple because I wanted them to review the previous content. Very funny stories came up!
