In a literature class, I'd probably use one of these assignments as an informal or journal writing. Most of these assignments can be easily modified to focus on students' reading process as well. Write a fable, tall tale, Uncle Remus tale, or fairy tale that will tell me about you as a writer and about your understanding of the writing process. Think about the genre of the tale you'll use. A fable, for instance, includes animal characters and tells a short didactic tale.
Fables end with a moral, a short, pithy saying that summarizes the lesson of the story.
It's a lot like putting your thesis statement at the end. To compose a fable about writing, think of a lesson you've learned as a writer and compose a tale that fits the characteristics of the genre. I'd probably offer two options rather than all four. Describe your biggest success as a writer. Pretend you are about to be interviewed on a show such as Today or the Barbara Walters special.
