Write an introduction that briefly explains the topic of the essay and provides at least three of the ideas you plan to present in the essay. Provide the information in a manner that will encourage the reader to continue reading the rest of the essay.
Write at least three paragraphs in the body. You should provide at least one paragraph for each idea you mentioned in the introduction. These paragraphs should ideally contain a topic sentence and at least four sentences that thoroughly explain that topic.
Provide a concluding paragraph that ties up any remaining details from the essay. Restate your three main ideas, using different words to reinforce those ideas. This is the one place where an emotional appeal is acceptable in an expository essay.
