This document summarizes 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 type of structure. 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 analyzing what the author is doing and looking for signal words.
