This document discusses different text structures used in writing. It defines text structure as how a piece of writing is organized. Different structures are used for fiction versus non-fiction. Six common non-fiction structures are then described: chronological order, compare/contrast, cause and effect, problem/solution, position/reason, and description/categorization. Each structure is defined, examples are given of how it organizes information, and key words typical of each structure are identified. The document aims to help readers understand and identify different text structures.
