This document provides guidance on writing an effective opinion paragraph. It explains that an opinion paragraph should follow the standard paragraph structure of a topic sentence, supporting details, and concluding sentence. The topic sentence should clearly state the opinion or viewpoint. It should not include phrases like "In my opinion." The supporting details are arguments or evidence to back up the opinion, and examples are helpful for clarifying the arguments. The concluding sentence should echo or rephrase the topic sentence to maintain unity. Coherence, organization, and persuasive language are important. The arguments should use facts rather than assumptions to convince the reader.
