Collect a list of superstitions from your friends, family or the internet. Write a story called "The Unlucky Day" or write a list poem using some of the superstitions you found.
Here is my example list poem on Poems of Silliness.
I have a free list poem product in my Teachers Notebook Store. List Poems is also available in my Teachers Pay Teachers Store.
Update October 2015: I recently packaged all my superstition activities as a freebie in my Teachers Pay Teachers and my Teachers Notebook stores.
