I LOVE Roald Dahl, he is one of my favourite children's authors and great to use as a teaching resource.
This is a fantastic presentation that links to the novel of 'The Witches' by Roald Dahl.
With lots of pictures and visuals that allow the concepts of theme, plot, setting and character to be taught over the course of a term (but easy to modify the length to suit your needs).
With 93 slides there is plenty to keep students busy as they read through the novel and easily adapted to use for learning goals and success criteria when teaching. It can also be used in conjunction to the film.
