Words to know

main idea
What a text is mostly about. The big idea.
detail
A small piece of information that tells more about the main idea.
retell
To tell a story again in your own words, in the right order.
sequence
The order things happen in: first, next, then, last.
beginning, middle, end
The three parts of a story.

What is it mostly about?

Imagine a friend asks, "What was that book about?" You would not say every word! You would tell the big idea.

The main idea is what a text is mostly about. The details are the small pieces that tell more about the main idea.

Main idea (tabletop)detaildetaildetail
The main idea is like a tabletop. The details are the legs that hold it up.

Read-aloud: Busy Beavers

Beavers are busy builders.

A beaver has strong front teeth. It chews through trees to cut them down.

Beavers build dams across streams with sticks and mud. The dam makes a pond.

In the pond, beavers build a home called a lodge. The doors to the lodge are under the water. This keeps the beavers safe.

Worked example

Let's find the main idea and details

What is Busy Beavers mostly about? What details tell more?

  1. Ask: What is the topic? Beavers.
  2. Ask: What does the text mostly say about beavers? That they build things. The first sentence tells us: "Beavers are busy builders."
  3. Find details that hold up the main idea: they chew trees with strong teeth; they build dams with sticks and mud; they build a lodge with doors under water.

Main idea: Beavers are busy builders. Details: strong teeth to cut trees, dams of sticks and mud, a lodge with underwater doors.

Funny but true

A beaver's front teeth are orange, and they never stop growing! 🦫 The orange colour comes from iron, which helps make them extra strong for chewing trees.

Look at the first sentence

In many fact texts, the first sentence tells the main idea. Check it by asking: "Do all the other sentences tell more about this?"

Retelling a story

When you retell a story, you tell the important parts in order, in your own words.

  • Beginning: Who is in the story? Where are they? What is the problem?
  • Middle: What happens?
  • End: How is the problem solved? How does it end?

Use order words: first, next, then, last.

Read-aloud: Leo Learns to Skate

Leo went to the outdoor rink with his big sister, Nia. It was his first time skating. Leo wobbled and fell down. Bump!

"I can't do it," said Leo.

Nia held his hands. "Push with one foot, then the other," she said. Leo tried again. He fell two more times. But he kept trying.

At last, Leo glided all the way across the ice by himself. "I did it!" he shouted. Nia cheered.

Retelling Leo Learns to Skate: the important parts in order, from the beginning to the end.
Worked example

Let's retell together

Retell Leo Learns to Skate using first, next, then, last.

  1. First, Leo went skating at the outdoor rink with his sister Nia, and he fell down.
  2. Next, Nia held his hands and showed him how to push with one foot, then the other.
  3. Then, Leo fell two more times, but he kept trying.
  4. Last, Leo skated across the ice by himself, and Nia cheered.

A good retell tells the important parts in order and uses our own words. We don't need every little detail.

Hands-on activity

Five-finger retell

You need: your hand and a favourite storybook.

  1. Read the story with your grown-up.
  2. Hold up one finger at a time and tell:
  • 👍 Thumb: Who is in the story?
  • ☝️ Pointer: Where does it happen?
  • Middle finger: First, what happens? (the problem)
  • Ring finger: Then what happens?
  • Pinkie: Last, how does it end?
  1. Bonus: Draw 3 boxes on paper. Draw the beginning, middle and end.

For parents and teachers

Big idea: Children learn to find what a text is mostly about (main idea), pick out supporting details, and retell stories in sequence. These are early summarizing skills.

How to help at home:

  • After reading, ask "What was that mostly about?" Accept short answers, then ask for one detail.
  • Use order words in daily life: "First we put on boots, next our coats, then our mittens, last our toques."
  • Let your child retell a story to a stuffed animal or a grandparent on a call.

Common difficulties:

  • Retelling every tiny detail. Use the five-finger retell to stay focused.
  • Giving one detail as the main idea ("Beavers have teeth"). Ask "Is the whole text about teeth? What is it mostly about?"
  • Mixing up the order. Draw quick beginning/middle/end boxes and put them in order together.
