Text structure describes how a writer arranges information within a piece. Most informational pieces use one of five typical structures: description, sequence, compare and contrast, cause and effect, or problem and solution. Fictional works instead use a narrative structure that includes characters, setting, plot and a resolution. If students can spot a text's structure, they are better able to guess what information will appear next, identify the main idea sooner and retain more of what they read.
What is text structure?
Every writer writes with a goal, and that goal shapes how the material is arranged. If the goal is to show how a volcano erupts, the writer will typically lay out steps in sequence. If the goal is to explain the Dust Bowl, the focus will be on linking causes with their effects. Text structure acts like a skeleton, holding ideas together whether the writing is a whole book, a chapter, a section, or a single paragraph.
Recognizing different text structures is an important skill for reading comprehension. The Institute of Education Sciences practice guide on improving reading comprehension in kindergarten through third grade recommends teaching children to notice and use how a text is organized. Text structure also appears in state English language arts standards, which expect students to explain the overall arrangement of events, ideas, concepts, or information in a text.
The five types of informational text structure
Informational text, which people also call expository or nonfiction text, is written to explain or give information. Examples include textbooks, articles, reports, and many websites. Teachers usually focus on five main informational text structures, often referred to as expository text structure patterns. Each pattern has common signal words—sometimes called clue words or transition words—that help readers recognize it.
1. Description
An author explains a topic by giving examples and noting its features or characteristics. These items do not need to follow any particular order.
Signal words: Words used include for example, for instance, such as, is like, includes, characteristics, in addition, also.
Example: "A monarch butterfly displays vivid orange wings marked by black veins and dotted with white spots. You can find them throughout North America. They drink nectar from a wide variety of flowers."
2. Sequence (chronological order)
The writer lays out events or steps in the sequence they occur. This format is used for timelines, biographies, recipes, and instructions.
Signal words: Use words like first, next, then, after, before, finally and during, along with dates and times.
Example: At first, the caterpillar breaks out of its egg. After that it feeds and grows larger. Later it forms a chrysalis around itself. In the end, an adult butterfly emerges.
3. Compare and contrast
The author explains how two or more things are alike (compare) and how they are different (contrast).
Signal words: similar, alike, both, same as, however, but, unlike, on the other hand, in contrast, whereas.
Example: "Frogs usually have smooth, moist skin, while toads tend to have dry, bumpy skin. Both frogs and toads are amphibians."
4. Cause and effect
The author explains why something happened (the cause) and what happened as a result (the effect).
Signal words: Common examples are because, since, so, as a result, therefore, due to, consequently, if...then, and leads to.
Example: Several years of scant rainfall in the region caused the crops to fail. Consequently, many families gave up their farms and moved away.
5. Problem and solution
The author describes a problem and one or more ways it was or could be solved.
Signal words: the question is, one way to, to fix this, solve, answer, problem, issue, challenge.
Example: "Many students forget their homework at school. One solution is a daily checklist that students review before leaving the classroom."
In real writing, different structures are often mixed — for instance, a chapter can be organized by sequence while a single paragraph within it illustrates cause and effect. Teachers tend to begin with short paragraphs that stick to one clear pattern and later introduce longer pieces that blend structures.
Text features vs. text structure
Text features and text structure are connected but not identical. Text features include elements like headings, bolded words, captions, diagrams, a table of contents, and a glossary that guide readers to and through information. Text structure refers to the way the ideas are arranged within the writing. Features such as a heading like "Causes of the Civil War" often signal the underlying structure.
Narrative text structure
Narrative texts tell a story. Fiction, folktales and many personal stories follow a predictable pattern often called story grammar:
- Characters: who the story is about.
- Setting: the time and place where the story happens.
- Problem or conflict: what the main character wants or must deal with.
- Events (plot): the actions that occur as the character works to fix the problem, typically building toward a high point.
- Resolution: the way the problem gets resolved and the story concludes.
Many teachers use a "story mountain" or plot diagram with exposition, rising action, climax, falling action and resolution. Understanding narrative structure helps students retell stories, make predictions and write their own stories.
Teaching text structure with graphic organizers
A graphic organizer gives each text structure a visual shape, which makes an abstract idea concrete:
- Description: a web or concept map with the topic in the center.
- Sequence: a numbered flow chart or timeline.
- Compare and contrast: use a Venn diagram or a T-chart.
- Cause and effect: use boxes joined by arrows to show relationships.
- Problem and solution: a box describing the problem that leads to one or more boxes showing solutions.
- Narrative: represented by a story map or a story mountain.
Effective text structure instruction usually follows a gradual release: the teacher names the structure and its signal words, models finding it in a short passage while thinking aloud, fills in the organizer with the class, then has students practice with partners and finally on their own. Students can also write short paragraphs in each structure, since writing and reading support each other.
A few practical tips for teachers and parents: introduce one structure at a time, use short and clearly organized passages first, keep a signal-word poster or card on the desk, and ask students to summarize a passage using the matching organizer. Over time, students learn to analyze longer texts and identify the key structure on their own.
Why text structure matters for students with learning disabilities
Many students with a learning disability, including dyslexia or a specific learning disability in reading comprehension, do not notice how a text is organized on their own. They may read a passage as a list of unconnected facts, which makes it hard to find the main idea or remember details. Students with working memory or executive functioning difficulties may lose track of ideas in longer texts.
Explicit teaching of text structure gives these students a plan for reading. Research reviews on students with learning disabilities have found that explicit instruction in text structure, often with graphic organizers, can improve their comprehension of expository text. It also supports metacognition, because students learn to ask themselves, "How is this text organized, and what am I looking for?"
Text structure instruction fits well with differentiated instruction and Universal Design for Learning. Helpful supports include signal-word lists, color-coding, partially completed organizers and shorter passages. For students with an IEP, a goal might read: "Given a grade-level informational paragraph, the student will identify its text structure and complete the matching graphic organizer with 80% accuracy in four of five trials."
Frequently asked questions about text structure
What are the 5 types of text structure?
Five commonly used informational text structures are description, sequence (chronological order), compare and contrast, cause and effect, and problem and solution.
Are there 7 types of text structures?
Some teaching materials list more than five by splitting or adding categories, for example separating chronological order from steps in a process, or adding question and answer or narrative structure. The core five remain the most widely taught.
How do you identify text structure?
Begin by asking what the author aims to do: describe something, give step-by-step directions, compare ideas, explain reasons, or offer a solution. Next, search for signal words and text features like headings that fit that purpose.
What is the difference between text structure and text features?
Text structure describes how ideas are arranged in writing. Text features are the tools—headings, captions, diagrams, bold words—that help readers move through and understand the text.
Why is it important to teach text structure?
Recognizing text structure helps students find the main idea, organize information, take notes, summarize and remember what they read. It also helps them organize their own writing.
