Home Activity: Author's Purpose

Help your child understand WHY authors write

Dear Families,

Your child is learning to identify the author's purpose—the reason an author wrote something. On the FAST test, students must not only identify whether the purpose is to persuade, inform, or entertain, but also EXPLAIN how they know using evidence from the text. Practice this skill everywhere—ads, articles, stories, and more!

Why This Matters for the FAST Test

The FAST asks questions like "What is the author's MAIN purpose?" and "Which sentence BEST shows the author's purpose?" Students must understand the difference between persuade, inform, and entertain—and find evidence to support their answer.

P = Persuade

To convince you to think, believe, or do something

I = Inform

To teach you facts and give information

E = Entertain

To make you enjoy, laugh, or have fun

Activity 1: Commercial Detectives

Spot persuasion in TV ads

  1. Watch 2-3 TV commercials together (or find ads in magazines).
  2. After each ad, ask: "What does this ad want you to DO or THINK?"
  3. Look for persuasion clues: "You should..." "The best..." "Don't miss..."
  4. Discuss: "How is the ad trying to convince you?"
Sample Discussion:
"This cereal commercial shows happy kids eating breakfast. They want us to BELIEVE their cereal is fun and will make kids happy. The clue words are 'the most delicious' and 'kids love it!'"

Activity 2: Book Purpose Sort

Identify purpose in different types of books

  1. Gather 5-10 books from around your home (fiction, nonfiction, how-to books, etc.).
  2. For each book, read the back cover or first page together.
  3. Ask: "Why did the author write this? To persuade, inform, or entertain?"
  4. Sort the books into three piles based on purpose.
  5. Discuss: Some books might have more than one purpose!
Examples:
Inform: Encyclopedia, science book, biography
Entertain: Comic book, fiction novel, joke book
Persuade: "Why You Should Recycle" (opinion book)

Activity 3: News vs. Opinions

Tell the difference between informing and persuading

  1. Find a news article AND an opinion piece about the same topic (or use examples below).
  2. Read both together. Ask: "Which one is trying to INFORM? Which one is trying to PERSUADE?"
  3. Find clue words that show the difference.
  4. Discuss: News articles have facts. Opinion pieces have words like "should," "must," "best," or "worst."
Inform: "The new library will open on March 15. It has 50,000 books."
Persuade: "The new library is the best thing for our town! Everyone should visit on opening day!"
