Identifying Author's Purpose in Informational Texts

Students determine why an author wrote a particular informational text (to inform, persuade, or entertain).

About This Topic

Author's purpose is one of the foundational lenses through which readers approach any text, and third grade is the right time to make it explicit. CCSS.ELA-Literacy.RI.3.6 asks students to distinguish their own point of view from the author's, but in practice this work begins by understanding why the author wrote the piece at all. The classic PIE framework (Persuade, Inform, Entertain) gives students a concrete starting vocabulary, though strong instruction in US third-grade classrooms moves students beyond labels to analyzing the specific evidence that reveals an author's purpose.

Students learn to examine word choice, the selection of facts, and the way information is sequenced to infer what the author wants the reader to think, feel, or do. A text that includes only positive information about a topic is likely persuasive even if it does not use obvious opinion language. A text that includes surprising or emotionally engaging anecdotes is probably aiming to entertain as well as inform.

Active learning is particularly valuable here because author's purpose is not always visible on the surface. When students discuss their interpretations in small groups and must justify their reasoning with specific text evidence, they encounter perspectives that challenge their initial read, which deepens their critical thinking about the texts they encounter in school and daily life.

Key Questions

1. How can we infer an author's purpose by analyzing their word choice and presentation of facts?
2. Differentiate between a text written to inform and one written to persuade.
3. Evaluate how an author's purpose might influence the selection of details in a text.

Learning Objectives

• Analyze word choice and factual presentation in an informational text to infer the author's primary purpose.
• Compare and contrast two informational texts on the same topic, identifying differences in author's purpose based on evidence.
• Explain how an author's purpose influences the selection and emphasis of details within an informational text.
• Classify informational texts into categories of 'to inform,' 'to persuade,' or 'to entertain' using textual evidence.

Before You Start

Identifying Main Idea and Key Details

Why: Students must be able to identify the main topic and supporting details to understand what information the author is presenting and why.

Understanding Text Features

Why: Recognizing headings, captions, and other text features helps students understand how an author organizes information to achieve a specific purpose.

Key Vocabulary

Author's Purpose	The main reason an author decides to write a piece of text. This could be to inform, persuade, or entertain the reader.
Inform	To give facts or information about a topic. Texts written to inform usually present objective details and explanations.
Persuade	To convince someone to believe or do something. Persuasive texts often present one side of an issue or use strong language to sway the reader.
Entertain	To provide enjoyment or amusement. Entertaining texts might use humor, interesting stories, or vivid descriptions.
Text Evidence	Specific words, phrases, or facts from a text that support an idea or interpretation, such as the author's purpose.

Watch Out for These Misconceptions

Common Misconception

Any text that contains facts is informational and cannot also be persuasive.

What to Teach Instead

Persuasive texts regularly use facts selectively to support a specific argument. Showing students two articles that use different facts about the same topic to reach opposite conclusions clarifies that fact-use alone does not determine purpose. Collaborative analysis activities where students highlight both facts and opinion language help them see the distinction.

Common Misconception

The author's purpose is always clearly stated somewhere in the text.

What to Teach Instead

Purpose must usually be inferred. Students should practice asking, 'What does the author want me to think or do after reading this?' Small group discussions where students defend their inference with evidence build the habit of examining the whole text, not just one sentence.

Active Learning Ideas

Think-Pair-Share: PIE Purpose Sort

Students read three short passages (one persuasive, one informational, one entertaining) without being told the purpose. Individually, they assign each a purpose and underline their key evidence. Partners compare their choices and work to reach agreement, then share with the class.

Collaborative Analysis: Word Choice Detective

Small groups receive the same two-paragraph article with highlighters in two colors: one for 'opinion or loaded words' and one for 'neutral fact words.' Groups compare their highlighted versions and draw a conclusion about whether the author is trying to inform or persuade, citing their highlighted evidence.

25 min·Small Groups

Socratic Discussion: Is This Persuasion?

Present a text that appears informational but contains subtle persuasive elements (e.g., only one side of a debate, emotional language). Students discuss as a whole class whether it is purely informational or contains persuasive intent, and what specific clues they used to decide.

Real-World Connections

• Advertisers for new toys or video games write product descriptions with the purpose to persuade consumers to buy them, using exciting language and highlighting benefits.
• Museum exhibit labels and informational brochures are written with the primary purpose to inform visitors about historical artifacts or scientific concepts.
• Children's book authors often aim to entertain their readers with engaging stories and characters, even when teaching a lesson or providing some factual information.

Assessment Ideas

Exit Ticket

Provide students with a short informational paragraph. Ask them to write one sentence stating the author's likely purpose (inform, persuade, entertain) and one piece of text evidence that supports their choice.

Quick Check

Display two short texts on similar topics but with different purposes (e.g., a factual description of bees vs. an ad for honey). Ask students to hold up a card or point to the text that is primarily meant to persuade and explain why.

Discussion Prompt

Present a text that might serve multiple purposes (e.g., an article about endangered animals that also calls for action). Facilitate a class discussion: 'What is the author's main goal here? How do the facts they chose help them achieve that goal? Could this text also be trying to do something else?'

Frequently Asked Questions

How do I teach the difference between informational and persuasive text to eight-year-olds?

Use concrete, familiar examples: a newspaper report about a school event (informational) versus a letter to the principal asking to change the lunch menu (persuasive). Have students identify what the author wants the reader to think or do. Making that distinction explicit with real-world texts removes the abstraction.

Is the PIE acronym enough for teaching author's purpose in third grade?

PIE is a useful starting point, but students should move beyond labeling to justifying. Ask not just 'which is it?' but 'what did the author do to achieve that purpose?' This prepares students for the more nuanced standard in later grades where purpose becomes tied to point of view.

How does active learning help students grasp author's purpose?

Author's purpose requires inferential thinking that benefits from collaborative sense-making. When students in small groups must agree on a purpose label and defend it with text evidence, the discussion often reveals that purpose can be layered (both inform AND persuade). Hearing classmates' reasoning helps students develop more flexible and evidence-based thinking about texts.

What do I do when students disagree about whether a text is informational or persuasive?

Treat the disagreement as the lesson. Ask both sides to find specific sentences that support their view, then chart them for the class. This meta-conversation about why reasonable readers can disagree is itself a higher-order comprehension skill and models the critical reading that CCSS RI standards are designed to build.
