Explain why Literacy narratives can often have slightly different focuses, so you have a small amount of room for creativity, but they primarily deal with detailing a persons path to reading and writing (education and experiences as a reader) and/or the impact that reading and writing has on their lives. Keep in mind that the focus here is on literacy (the act of reading and/or writing) and not as much on literature (which well be talking about in class). Your literacy narrative can involve your experiences with various great books, but it will more likely encompass your experiences with a variety of texts, from internet reading, to newspapers, to comic books, to whatever you tend to read or even write in your spare time.
The organization of your paper will depend on the focus you want the essay to take. If you are writing about your experience becoming literate (learning to read and write).
