How to Teach Author's Purpose
Your child reads a cereal box, a chapter book, and a science article in the same day. They process the words, understand the sentences, and move on. What they probably do not notice is that each of those texts was written for a completely different reason — and that reason shapes everything about how the text is written and how it should be read.
Author's purpose is the skill of asking "Why did the author write this?" It sounds simple, but it is the gateway to critical reading. A child who understands author's purpose reads more skeptically, evaluates information more carefully, and understands why a text feels the way it does.
The three core purposes
Most elementary instruction organizes author's purpose into three categories, often remembered with the acronym PIE:
Persuade — The author wants to convince you of something. Advertisements, opinion pieces, book reviews, and persuasive essays fall here. The author chooses words and evidence designed to change your mind.
Inform — The author wants to teach you something. Textbooks, news articles, encyclopedias, and how-to guides fall here. The author presents facts and explanations.
Entertain — The author wants you to enjoy the experience. Novels, poetry, jokes, and comics fall here. The author uses storytelling, humor, or creativity to engage you.
These categories overlap — a funny science book both entertains and informs — but they give your child a starting framework for thinking about why texts exist.
Key Insight: Author's purpose is not just an academic exercise. It is a life skill. A child who can identify when they are being persuaded is a child who can think critically about advertisements, social media, and political arguments. This skill matters well beyond reading class.
Start with familiar texts
The best way to teach author's purpose is with texts your child already encounters:
- Cereal box: Why did someone write this? To persuade you to buy the cereal. Notice the exciting words, the bright colors, the claims about how delicious it is.
- Recipe: Why was this written? To inform you how to make something. Notice the step-by-step structure and precise measurements.
- Joke book: Why was this written? To entertain you. Notice how the author sets up expectations and then surprises you with the punchline.
- Letter from Grandma: Why was this written? To connect and share news — a blend of informing and entertaining.
When you use everyday texts, author's purpose stops being abstract and becomes obvious. Your child can see it and feel it in materials they already know.
How purpose shapes the writing
The most powerful lesson is showing your child how author's purpose affects what the text looks like. The same topic — let us say, dogs — looks completely different depending on the author's purpose:
To inform: "Dogs are domesticated mammals belonging to the family Canidae. There are over 340 recognized breeds, ranging in size from the Chihuahua to the Great Dane."
To persuade: "Every family should consider adopting a dog. Dogs provide companionship, encourage exercise, and have been shown to reduce stress and anxiety."
To entertain: "Max the golden retriever had one job: guard the turkey on the kitchen counter. He lasted approximately four seconds."
Read all three aloud and ask: "How are these different? Why do they sound different?" Your child will begin to see that the author's purpose determines the word choices, the tone, and the structure.
Key Insight: Teach your child that author's purpose is not just about what the text says — it is about how and why the text says it. The same topic, written with a different purpose, produces a completely different text. That is the power of understanding purpose.
Identifying purpose in longer texts
With short passages, purpose is usually straightforward. With longer texts, it gets more nuanced. A novel primarily entertains, but it might also inform (historical fiction teaches about a time period) or persuade (the author might have a message about fairness or kindness).
Teach your child to identify the primary purpose — the main reason the author wrote the text — while acknowledging that secondary purposes may exist.
Ask:
- "What is the main reason the author wrote this?"
- "Is the author also trying to do something else?"
- "How do you know?"
That last question is critical. Your child should be able to point to evidence in the text that supports their answer. "I think the author is trying to persuade because they use phrases like 'everyone should' and 'the best choice is.'"
Clues that reveal purpose
Teach your child to look for these clues:
Persuasion clues: opinion words (best, worst, should, must), emotional language, one-sided arguments, calls to action
Informing clues: facts and statistics, neutral tone, definitions, step-by-step instructions, diagrams or charts
Entertainment clues: dialogue, suspense, humor, vivid descriptions, character development, plot twists
Post these clue categories somewhere visible during reading time and practice identifying them together.
Moving toward critical reading
Once your child can reliably identify author's purpose, push toward critical analysis:
- "The author says this product is amazing. But what is their purpose? They are trying to sell it. Does that change how much you trust the claim?"
- "This article gives a lot of facts about climate. Is the author just informing, or are they also trying to persuade you to think a certain way? How can you tell?"
- "This story has a clear moral about honesty. Is the author just entertaining, or are they also trying to teach a lesson?"
These conversations build media literacy and critical thinking — skills your child will need for the rest of their life.
Key Insight: Author's purpose becomes truly powerful when your child connects it to trustworthiness. A text written to inform is structured differently from a text written to persuade — and recognizing that difference helps your child evaluate whether the information is reliable.
Common mistakes to watch for
Confusing topic with purpose: "The author wrote this to tell us about dolphins." That is the topic. The purpose is to inform (or persuade, or entertain) — it is why the author wrote, not what they wrote about.
Assuming fiction is always entertainment: Some fiction has a strong persuasive or informational purpose. Fables teach lessons. Historical fiction informs about real events. Help your child look deeper.
Forgetting that purpose can be mixed: Most real-world texts blend purposes. A nature documentary both informs and entertains. An editorial both informs and persuades. Encourage nuance.
Author's purpose is the question that turns a reader into a thinker. When your child asks "Why was this written?" before absorbing a text, they are building the critical reading habits that will serve them in school, in media consumption, and in life.
