Extracting the main idea - ESL worksheet by cacucacu - Free Printable

Let’s go through each paragraph one by one and find the main idea.

---

First Paragraph: Koala vs. Kangaroo

The paragraph says:
- Many people think a koala is a bear → but it’s not.
- A koala is a marsupial (like a kangaroo).
- Both carry babies in pouches, but in different places (kangaroo = front, koala = back).
- Both feed babies milk and keep them safe until they’re strong.

So what’s the big point? It’s showing that koalas and kangaroos are similar (both marsupials with pouches) but also have differences (where the pouch is). The best answer should cover both similarities AND differences.

Look at the choices:
a. “The koala is not a bear.” → True, but too small — doesn’t cover the whole paragraph.
b. “The kangaroo is nothing like the koala.” → False! They’re actually quite alike.
c. “The kangaroo and koala are mostly alike but have some differences.” → YES! This matches everything said.
d. “Exactly alike” → No, because their pouches are in different places.

✔ So for #1, the answer is c.

Second Paragraph: Lucy’s Messy Room

The paragraph says:
- Lucy’s room looked like a tornado hit it.
- She couldn’t believe how much damage her friends did.
- Friends pulled things out, didn’t put anything back.
- Glue on rug, nail polish on bedspread, chocolate on curtains.
- Ends with: “Wow! What a mess.”

What’s the main point? It’s about how messy the room got because of what her friends did.

Choices:
a. “There is glue on the rug.” → Too specific — just one detail.
b. “Lucy’s friends are messy.” → Close… but the paragraph says *they made* the mess, not that they’re always messy.
c. “A tornado hit the house.” → Nope — that was just a comparison (“looked like”).
d. “Lucy’s friends ate chocolate.” → Again, just one tiny part.

Wait — let’s reread: “She couldn’t believe how much damage her friends had done.” And then lists all the messes they caused. So the main idea is that her friends created a huge mess.

But none say “her friends made a mess” exactly… Hmm.

Actually, option b says “Lucy’s friends are messy.” That might be the closest — even if it’s not perfect, it’s the only one that points to the friends causing the mess.

BUT — wait! Let’s look again. The paragraph starts with “Lucy would never get her room clean. It looked like a tornado had hit it.” Then explains WHY — because her friends messed it up.

So maybe the main idea is that the room is a mess because of her friends’ actions.

Still, among the options, b is the best fit — it implies the friends are responsible for the messiness.

Alternatively… could there be a better way?

Actually, no — the other options are clearly wrong. So we pick b.

Wait — hold on! Let me check again.

Option b: “Lucy’s friends are messy.” — The paragraph doesn’t say they’re generally messy — just that THIS time they made a mess. But since that’s the only choice that connects the friends to the mess, and the others are facts or false, we go with b.

✔ So for #2, the answer is b.

Third Paragraph: Tim’s Fishing Trip

Paragraph says:
- Tim and family went fishing today.
- Stopped at lake, bought snacks.
- Started fishing → Tim caught 4, brother caught 3.
- Laughed, gave high-fives every time someone caught fish.
- Whole family had a great time.
- Maybe they’ll go again soon.

Main idea? It’s not just about catching fish or eating snacks — it’s about the whole experience being fun and enjoyable for everyone.

Choices:
a. “Tim caught four fish.” → Just a detail.
b. “He ate his favorite snack.” → Also a detail.
c. “The family had a great time.” → YES! That’s repeated: “laughed,” “high-five,” “whole family had a great time,” “maybe go again.”
d. “They ate fish for supper.” → Not mentioned at all!

✔ So for #3, the answer is c.
