There is a great resource on Teachit ( I believe), written by Fran Nantongwe called “Quest for the cure”. I got a copy a while ago through a colleague at a NATE conference and love using it in Year 7.
The idea is that the class develop a novel through pieces of creative writing – all transactional and with a particular focus – persuasive, descriptive etc.
It is brilliant and Fran is a star for developing so much. I attach my PowerPoint for teaching the module, a few of the resources I use to help the students to write and 2 booklets of work from this Year’s Year 7s.
