Record your central thesis statement at the top of your outline page. Each paragraph of an expository composition must support this thesis using anecdotal or factual evidence. For example, if the topic of your composition is bullying, your thesis statement must articulate what the paper will prove or illuminate regarding bullying.
Outline the paragraphs of your expository composition with your thesis as the central starting point. Divide the paragraphs by subject and assign each one two or three points of evidence. For an expository composition on bullying, for example, create three or four paragraphs with subjects such as history, national trends, current disciplinary measures and proposed solutions.
Arrange the evidence paragraphs in a logical order that proves your thesis. Experiment with different sequence orders to determine the most compelling arrangement.
Write the opening paragraph with your thesis as the concluding sentence. The opening of your expository essay must introduce the subject matter in an objective by compelling way. For example, introduce the subject of bullying by describing a recent incident within the community.
Write your supporting paragraphs of evidence using the order outlined in steps two and three. Explain individual points or anecdotes as though the audience knows nothing about the subject. Educating and informing the reader is critical when writing an effective expository essay.
Write the concluding paragraph of your expository composition. This section must summarize the main points or examine the issue from an alternative angle. For example, an expository essay examining how school administrations handle bullying would conclude by explaining how students could protect themselves and others from bullying.
