Nobody has ever asked me for advice about how to teach and I don’t think they ever will. But if they do, I’ll say this: If you’ve got a good text to share and some good questions to ask, everything might be fine.
As well as being good and well-written and worthy in their own right I think that these stories are all broadly appropriate for study with 11-18 year olds. In my experience they ‘work’, either as something fun to read aloud, or as something thought-provoking to discuss.
If you are a teacher and you would like PDFs of the stories, do get in touch.
