This activity is so much fun as students go "trick-or-treating" for must-haves in their Halloween-themed scary story.
I start students off with a short snippet to write from about Halloween night and spooky things happening, then I let them write for a little while. As they are writing, I give them must-haves to include in their story. All of these must-haves are Halloween-themed to make their story extra scary.
This is a great activity to get students writing and enjoying a little bit of Halloween. Format can be adopted to any holiday or topic.
