After describing some images of classical tales frozen on the stage...
...we played the funny game "Sausage" - they forget they are shy and afraid of speaking- and then, in a three/four-people team, they were given the beginning of a sentence and started a story.
They wrote the next line and passed the paper to another team to go on with the story.
- I've got a good story. Would ypu like to listen to it?
- Oh, it's so boring. What can we do?
Next day we'll see if they are imaginative enough as to present a good story.
