1. Before writing a first draft: Organizing paragraphs *before* you start writing helps ensure a logical flow and prevents you from getting bogged down in revising structure later. This involves outlining your main points and sub-points, and then deciding which points will form the basis of individual paragraphs. This pre-writing stage allows for a more coherent and well-structured piece.
2. After writing a first draft (but before editing for grammar and style): Once you have a complete first draft, reviewing paragraph structure is crucial. This allows you to see the overall flow of your argument and identify places where paragraphs are too long, too short, disjointed, or don't logically follow each other. You can then restructure, combine, split, or rewrite paragraphs to improve clarity and coherence.
