It can easily be adapted to any other languages if you just change a couple of words.
It takes up a lesson and it works well for differentiation as it is an open task including a personalised vocab. mat that students create prior to choose a topic to write about.

It prepares them for the new GCSE spec where they have to write on the spot about different topics.
