What Is Expository Text
Expository text explains, describes, or informs the reader about a topic. It's the primary text type students encounter in school starting around 3rd grade, with complexity increasing through middle and high school. Science textbooks, news articles, biographies, how-to guides, and encyclopedia entries are all expository. Unlike narrative text, expository doesn't tell a story. Unlike persuasive text, it doesn't argue a position, though it presents factual information clearly.
For struggling readers and students with dyslexia, expository text presents specific challenges. The dense vocabulary, complex sentence structures, and expectation that readers extract main ideas make expository text harder to decode and comprehend than narrative. Many children read fluently through a story but stumble on a science passage because the text demands both accurate word recognition and active comprehension strategies simultaneously.
Why It Matters for Struggling Readers
By 4th grade, reading shifts from "learning to read" to "reading to learn." About 70% of school reading time involves expository text, yet struggling readers often receive instruction focused primarily on narrative comprehension. This gap widens the achievement gap considerably.
Students with dyslexia using Orton-Gillingham instruction benefit from explicit phonics work on expository vocabulary, which tends toward multisyllabic, Latin-based words. IEPs should include specific goals around expository text comprehension, not just fluency. Research shows that teaching struggling readers to identify text structure (compare-contrast, cause-effect, sequence, problem-solution) improves comprehension of expository passages by 25-30%.
Teaching Strategies for Expository Text
- Preview the text: Walk through headings, subheadings, and images before reading to activate prior knowledge and predict what the passage will explain.
- Highlight text structure: Mark signal words like "because," "as a result," "first," "finally," or "similarly" to help students see how information connects.
- Use graphic organizers: Concept maps, T-charts, and sequence charts help struggling readers track main ideas and supporting details.
- Restate information: Have students explain key points in their own words to check understanding before moving forward.
- Match phonics to vocabulary: For students learning through Orton-Gillingham, pre-teach multisyllabic words and morphemes common in expository text (like prefixes "sub-" or "pre-").
Common Questions
- How is expository different from informational text? Informational text is a broader category that includes both expository and other text types that convey facts. Expository specifically explains or describes a topic in depth.
- Should I teach expository text differently to a child with dyslexia? Yes. Pre-teach vocabulary using structured phonics, use multisensory approaches, break passages into smaller chunks, and explicitly teach text structure. Most children with dyslexia need 2-3 times more exposure to expository vocabulary than typically developing readers.
- What reading level should my child handle expository text? Children typically engage with grade-level expository text 1-2 grade levels below their narrative reading level. A 4th grader reading at a 3rd grade level for stories might read 2nd grade expository text comfortably.
