My thesis has to answer: what is the portrayal of children in The Little Prince. Children are described as imaginative, innocent, and open minded, but I'm not sure I could turn that into a thesis or how to format the essay with that information.
This would be a thesis: Throughout the story, " The Little Prince" by Antoine de Saint-Exupéry, the children are described as imaginative, innocent, and open minded. The thesis should tell the reader exactly what you are going to write about later in the essay. The thesis should also be the last sentence in the introductory paragraph.
To format the essay write a body paragraph per trait. You would have 3 paragraphs, one per trait about the children.
