Make sure your paragraph has 3 distinct parts. 1. Topic sentence: 1. This sentence is the first sentence of a paragraph and summarizes the main idea of the paragraph. 2. All of the following sentences will add information that expands upon or supports the idea stated here. 2. Supporting sentences: 1. The second sentence identifies the first major supporting detail. 2. The third sentence brings up a second supporting detail. 3. Similarly, the fourth sentence mentions a third supporting detail. 4. Additional sentences can be added here for additional supporting details or to divide one lengthy supporting detail into separate, easier-to-read sentences. 3. Conclusion: 1. The last sentence of your paragraph is your concluding sentence, which quickly ties your supporting thoughts together. 2. It also might restate your first topic sentence using different terms.
