This document discusses different patterns of paragraph development that writers can use to organize ideas. It identifies four main patterns: 1) Narration and description, which focuses on telling a story or providing details about people, places, or things. 2) Definition, exemplification, and classification, which aims to explain or define concepts. 3) Cause and effect and comparison/contrast, which analyzes how things are similar/different or why things happen. 4) Problem-solution and persuasion, where an issue is presented along with a resolution or argument is made to convince readers. For each pattern, the document provides examples and explanations of how to structure paragraphs using that organizational strategy.
