This document discusses six common patterns of text structure: chronological, cause and effect, compare and contrast, problem and solution, sequence/process, and spatial/descriptive. It provides examples and definitions for each pattern. Chronological structure organizes information in time order, while cause and effect explains an action and its results. Compare and contrast tells how two things are similar and different. Problem and solution suggests a problem and answer. Sequence/process lists steps in order. And spatial/descriptive describes something in terms of space. The document advises identifying text structure by determining the author's purpose and looking for signal words.
