This document provides guidance on identifying the theme of a story using the Pixar film Finding Nemo as an example. It explains that the theme is the overall message or idea that an author wants to convey. To identify a theme, one must first determine the big idea or topic of the story, then make inferences about what the author is saying about that topic. For Finding Nemo, the big idea is determined to be "trust." After analyzing key events in the film, the identified theme is: "Sometimes you have to let go and trust in your friends and family." The document then models using the same process to identify the theme of another story.
