What Is Nonfiction?
Nonfiction refers to writing that is based on facts and real events. Unlike fiction, which is made-up or imaginary, nonfiction deals with true information about the world. It presents ideas or tells stories about real people, places, or events. Nonfiction can include many forms such as books, articles, and reports – as long as the content is factual.
Examples of Nonfiction:
- Textbooks
- Biographies of famous people
- News articles
- Science books
- Diaries and journals
Types of Nonfiction
Nonfiction comes in several types or categories. In 4th grade, you should know about three major types of nonfiction writing and some sub-types:
1. Narrative Nonfiction (Telling a True Story)
Narrative nonfiction is a type of writing that tells a true story, often using elements like characters, setting, and a plot. This type includes:
- Biography – A biography is the story of a person's life written by someone else. It includes factual details about the person's childhood, family, and career.
Example: A book about the life of Martin Luther King Jr. written by another author.
- Autobiography – An autobiography is the story of a person's life written by that person themselves.
Example: Helen Keller writing about her experiences growing up without sight or hearing.
| Biography (Life story by another) | Autobiography (Life story by oneself) |
| Written by someone else | Written by the person themselves |
| Uses third-person pronouns (he, she) | Uses first-person pronouns (I, me) |
| Example: Who Was Walt Disney? | Example: Diary of a Young Girl by Anne Frank |
Other types of narrative nonfiction include memoirs (focusing on a specific time in someone's life) and personal journals/diaries.
2. Expository Nonfiction (Providing Information)
Expository nonfiction is writing that explains, informs, or gives factual information about a topic. The purpose is to educate the reader about real-world topics in a clear, organized way.
Examples:
- Textbook chapters
- Informational articles
- Science and history books
- Encyclopedia entries
Expository writing often includes main ideas and supporting details to present information clearly.
3. Persuasive Nonfiction (Sharing Opinions and Arguments)
Persuasive nonfiction is writing that tries to convince the reader about a certain opinion or to take a specific action. The author presents arguments, reasons, and evidence to persuade the reader to agree with their viewpoint.
Examples:
- Opinion essays
- Persuasive letters
- Speeches
- Newspaper editorials
Persuasive writing supports its viewpoint with facts and logical reasoning.

Nonfiction Text Structures (Organization of Ideas)
Nonfiction writing is structured in different ways. Understanding text structures helps readers find information easily.
| Text Structure | Description | Example |

| Sequence/Chronological | Presents events in time order. | A history book listing events leading up to the American Revolution. |
| Cause and Effect | Shows how one event leads to another. | An article explaining how pollution causes climate change. |
| Compare and Contrast | Explains how two things are similar and different. | A passage comparing frogs and toads. |
| Problem and Solution | Presents a problem and suggests solutions. | An article about plastic pollution discussing recycling as a solution. |
Nonfiction Text Features (Formatting and Visual Aids)
Nonfiction texts often include text features that help readers locate and understand information quickly.
| Text Feature | Description | How It Helps |
| Title | The name of the book or article. | Tells what the text is about. |
| Heading | A short title for a section. | Breaks the text into sections. |
| Subheading | A smaller heading. | Organizes information under main headings. |
| Table of Contents | A list of chapters with page numbers. | Helps find topics quickly. |
| Index | An alphabetical list of topics with page numbers. | Helps look up specific terms. |

Main Idea and Supporting Details
The main idea is the most important point of a text. Supporting details help explain or prove the main idea.
How to Find the Main Idea:
- Ask: What is this text mostly about?
- Look for key sentences that introduce the topic.
- Find supporting details that explain or give evidence.
Example:
- Main Idea: Exercise is good for health.
- Supporting Details:
- Exercise strengthens the heart.
- It improves mood by releasing endorphins.
- It helps control weight by burning calories.
Author's Purpose
The author's purpose is the reason for writing the text. It usually falls into three categories: Persuade, Inform, Entertain (PIE).
| Purpose | Description | Examples |
| Inform | Provides facts and teaches something. | Textbooks, news articles. |
| Persuade | Tries to change opinions or actions. | Advertisements, opinion essays. |
| Entertain | Engages the reader with true stories. | Memoirs, travel stories. |
Ask: What is the author trying to do? If the goal is to educate, it is to inform. If the goal is to convince, it is to persuade. If it tells an interesting true story, it is to entertain.
Fact vs. Opinion
A fact is a statement that can be proven true or false. An opinion expresses someone's belief or judgment and cannot be proven.
| Purpose | Description | Examples |
| Inform | Provides facts and teaches something. | Textbooks, news articles. |
| Persuade | Tries to change opinions or actions. | Advertisements, opinion essays. |
| Entertain | Engages the reader with true stories. | Memoirs, travel stories. |
Checking facts: Facts can be verified with evidence. Opinions cannot be proven but may be supported with reasoning.
