For a shorter paper, the above might represent three paragraphs; if you are writing a long paper and have a great deal of information, you may choose to write about each point, A, B, and C, in separate paragraphs for a total of six. However you decide to organize, make sure it is clear why you are examining this subject. You might be able to compare apples and oranges, for example, but why would you? Include any insights or opinions you have gathered. And yes, in general, three is the magic number. While there is no hard-and-fast rule that precludes creating a paper based on two points, or four, or five, a three-point discussion is manageable, especially for complex or abstract subjects. At the same time, a three-point structure helps you avoid oversimplifying, especially when addressing controversial topics in which discussions tend to become polarized–right or wrong, black or white, for or against. Three-point treatments encourage discussion of the middle ground.
This interactive guide provides an introduction to the basic characteristics and resources that are typically used when students compose comparison and contrast essays. The Comparison and Contrast Guide includes an overview, definitions and examples. The Organizing a Paper section includes details on whole-to-whole (block), point-by-point, and similarities-to-differences structures. In addition, the Guide explains how graphic organizers are used for comparison and contrast, provides tips for using transitions between ideas in comparison and contrast essays, and includes a checklist, which matches an accompanying rubric .
