One of my old schools did a great job of communicating with their feeder Primary Schools. We would be invited in to teach the incoming Year 7s. We took this a stage further by collaboratively teaching lessons with people from other departments. This lesson is designed to be taught to Year 6 students and combines Art and English. It's quite easy to change this to meet the needs of your own school's transitional needs. You'll need to download some Manga style pictures and also, somewhat unsurprisingly, you'll need Art resources too.
