Answer:
The main idea of a text is what the text is mostly about. Think about it this way: If you were to read a story, and then tell a friend in one or two sentences what the story is about, chances are that you have described the main idea of the story. When describing the main idea, you might describe details such as who the characters are and what the conflict of the story is.
The theme of a story is harder to determine. The theme is the underlying message or lesson that a reader takes away from a story. The author will not state the theme directly, but the events in the story will help the reader determine the theme or themes. When determining the theme of any story, pay close attention to the main conflict and how it is resolved (or not resolved!) in the story. The theme goes beyond the text. You will never use a character's name or specific events in the story to describe theme.
