An informative essay has five parts:
1. Introductory paragraph.
2. First body paragraph.
3. Second body paragraph.
4. Third body paragraph.
5. Concluding paragraph.
A thesis statement appears in the introductory paragraph of an informative essay, usually by the end. It offers a brief summary of the claim of the essay. A thesis statement serves as the focus sentence for the entire essay (all parts) thus providing organization.
