I'm looking for a single book that I can read with a mixed ability year 7 class and a mixed ability year 9 class. It is purely for pleasure - no assessments etc. attached. However, I would really like it to increase their cultural capital and, things being as they are, copies of the book need to be cheap - I'm talking £2.50ish. I've been looking at the Wordsworth children's classics. I also really like the idea of Greek myths, but I'm struggling to find a collection that fits our budget. The main thing is that it's quality stuff that the kids enjoy. Any ideas?
