Teaching Informative Writing in Elementary

Teaching Resources › Writing Teaching Guides › Teaching Informative Writing

Ask students to write everything they know about sharks and you’ll get a page of true facts in no particular order: sharks have sharp teeth. sharks live in the ocean. some sharks are big. my cousin saw a shark once. Every sentence might be accurate, but it isn’t informative writing yet — it’s a fact dump. Informative writing is the genre that teaches students to take what they know and organize it so a reader actually learns something. This guide covers how to teach informative (expository) writing in grades 3–6, and pairs with the printable informative writing prompts and activities for classroom practice.

Informative writing — also called expository or explanatory writing — is the workhorse genre of school. It is how students write reports, summaries, how-to pieces, and answers to test questions, and it underlies almost everything they’ll write in science and social studies. It is also the genre where “I have nothing to say” is least true and structure matters most: the content is already there, and the teaching is mostly about shaping it.

What Informative Writing Is — and Isn’t

Informative writing explains a topic or teaches the reader how to do something. Its job is to inform, not to argue or to tell a story. Hold that line clearly, because students blur the three genres constantly:

• Informative: explains, describes, or teaches. Sharks are fish that have lived in the ocean for millions of years. The writer’s goal is to help the reader understand.
• Opinion: argues a position. Sharks are the most fascinating animals in the ocean. The writer wants the reader to agree.
• Narrative: tells a story. The morning I saw my first shark, the water went strangely quiet. The writer wants to take the reader through events.

The key feature that makes writing informative is that it stays focused on a topic and the reader’s understanding of it — not the writer’s feelings about it. A useful rule for students: in informative writing, you can disappear. The piece is about the topic, not about you.

The Shape of an Informative Piece: Introduction, Body, Conclusion

Informative writing has a dependable three-part structure, and giving students that frame turns a fact dump into a piece a reader can follow. Three parts, in order:

1. Introduction. Name the topic and tell the reader what the piece will cover. A strong intro often opens with a hook (a surprising fact or a question) and ends with a sentence that previews the main points.
2. Body. Two or three paragraphs, each focused on one main idea about the topic, with facts and details that develop it. This is most of the piece.
3. Conclusion. Wrap up by restating the topic and the big takeaway — what the reader should remember.

The body is where informative writing lives or dies, and the move that organizes it is grouping: instead of listing facts randomly, students sort related facts together so each paragraph covers one subtopic (what sharks eat / where they live / how they have babies). This is exactly how the informative writing lessons build the skill — gather facts, then group them into focused paragraphs before drafting.

Facts and Details: Teaching Students to Develop a Topic

The single most useful informative-writing skill is developing a main idea with specific facts and details — and it’s the one students most often shortchange. A main idea sentence with no support is just a heading. Teach the layering explicitly:

• Main idea: Sharks are well-built for hunting.
• Supporting fact: A shark can have several rows of teeth, and lost teeth grow back.
• Specific detail: Some sharks go through thousands of teeth in a lifetime.

The test to teach students: after every main-idea sentence, ask “what facts and details prove or explain this?” A strong informative paragraph reads as a main idea followed by two or three pieces of specific support — not one general sentence repeated three ways. Where the facts come from matters too: model pulling details from a text, a diagram, or notes, rather than from memory alone, so students learn that informative writing rests on sources.

Text Features and Transitions That Help the Reader

Informative writing has its own toolkit for guiding a reader, and a short lesson on each pays off immediately. Two are worth teaching directly:

Transitions that signal organization

Informative pieces lean on transitions that show how information is organized — first, next, finally for steps and sequence; for example, in addition, another for adding facts; because, as a result for cause and effect. These signposts tell the reader how the pieces fit. The guide on transitional words and phrases covers the ones informative writers use most.

Text features that organize information

Headings, labeled diagrams, captions, and bulleted lists are part of informative writing, not decoration. Teaching students to add a heading to each body paragraph, or to caption a diagram, doubles as a planning tool: if a student can write a clean heading for a paragraph, that paragraph has a clear main idea. If they can’t, it doesn’t yet.

Where Students Get Stuck (and How to Help)

Four problems account for nearly every weak informative draft. Naming each one for students — and giving it a fix — does far more than “add more detail” feedback.

1. The fact dump

True facts in random order, with no grouping and no main ideas. Fix: the grouping move. Have students sort their facts into 2–3 piles before drafting, and make each pile a paragraph with a main-idea sentence on top.

2. Main ideas with no support

Each paragraph is one general sentence and then it moves on. Fix: the “what facts and details prove this?” question after every main-idea sentence. One well-developed paragraph beats three thin ones.

3. Opinion creeping in

Sharks are the coolest animals ever. The writer slides from informing into arguing. Fix: the “you can disappear” rule — flag feeling words (coolest, best, amazing) and ask whether the sentence teaches the reader something or just says what the writer thinks. (When the goal is to argue, that’s a job for opinion writing instead.)

4. No real introduction or conclusion

The piece starts with the first fact and stops at the last one. Fix: teach that the introduction names the topic and previews the points, and the conclusion restates the takeaway. The same care students learn for conclusion paragraphs transfers directly to landing an informative piece.

A Suggested One-Week Mini-Unit

Informative writing rewards a gather-group-draft sequence that ends in one organized piece, rather than a single “write a report” assignment. A workable one-week shape:

• Day 1 — What informative writing is. Sort informative vs. opinion vs. narrative sentences; pick a shared class topic.
• Day 2 — Gathering facts. Pull facts from a text or diagram onto note cards or a chart — sources, not memory.
• Day 3 — Grouping. Sort the facts into 2–3 subtopics; write a main-idea sentence for each group.
• Day 4 — Drafting. Write the full piece: introduction, body paragraphs from the groups, conclusion.
• Day 5 — Revise and share. Add transitions and a heading per paragraph, strengthen the thinnest paragraph, read finished pieces aloud.

The drafting and revision days pair naturally with the broader guide on paragraph writing — each body paragraph of an informative piece is a paragraph with a clear topic sentence and supporting details.

Where Informative Writing Goes Next

The informative-writing skills students build in elementary school are the foundation for most of the academic writing that follows.

• Research reports and essays. The gather-group-organize process scales directly into the multi-source research papers of middle and high school.
• Writing across the curriculum. Lab write-ups, social-studies reports, and short-answer test responses are all informative writing in disguise.
• Reading comprehension. Students who write informative text read it better — they recognize text structures, use headings and features to navigate, and pull out main ideas and details.
• Standardized writing tests. Informative/explanatory is one of the three core text types assessed on most state ELA exams, alongside narrative and opinion/argument writing.
