Okay, I've dug up some more Harry Potter oriented lesson materials that were gathering dust in the Raven Vault! Even if they're not quite right for your actual classroom use, I hope at least they can give you some materials writing ideas.
First of all, a series of lesson materials based around the first chapter of the first Harry Potter book (depending on where in the world you live: Harry Potter and the Philosopher's Stone or Harry Potter and the Sorcerer's Stone). They are quite high level (post-intermediate at least), on account of the input but also because I basically developed these materials to use as examples in a teacher development seminar (hence wanted it to be reasonably challenging for the teachers, too!). I had just taken over DoS responsibilities at a school that insisted on having different teachers for different skill areas (so learners had four different teachers all focusing on something different - reading, grammar, listening/speaking, and writing; and each teacher used a completely different textbook). I wanted to show the school and teachers how we might use a more integrated approach with united topical content, while still allowing for skill-specific focus. I was also getting reading to implement a more process-oriented approach to the writing curriculum and wanted to show the teachers how this worked through real examples as well.
READING & VOCABULARY
There's also a nice little cover to go with the materials above if you want to put them together and create a unit 'kit':
But that's not all! (Ready for the free steak knives pitch?)
I also found some related materials I developed for an advanced group of teenagers using Harry Potter and the Order of the Phoenix as their main reading material:
All of these materials were exhausting to make, but they worked brilliantly in the classroom (given the massive topical appeal to learners) and I had high hopes of making many more of the same type for all of the books at differing levels of English proficiency. I thought at the time that I was really onto something and I might even get some writing work out of it! That was, until Peter Usborne politely asked in an email me how on earth I'd managed to get permission from the Rowling Empire to feature the actual name Harry Potter on any of my potentially commercial materials... There went that idea!
There are some more Harry Potter learning materials elsewhere on this blog, too:
