Truth, Lie and Opinion: For Kids

Critical Thinking: Ages 6-8

What Is True? A Little Lesson in Thinking

Let's learn three big words: Truth, Lie, and Opinion — and how to tell them apart.

Have you ever said something is "true" or "false" without really knowing why? That's okay — most people do! Let's figure out what these words really mean.

✅ Truth

A truth is something we said, and when we look at the real world, it matches. It's real, and we checked it.

Example: "Cats have four legs." Go look at a cat — yep, four legs! That matches the real world, so it's true.

❌ Lie (or False)

A lie, or a false statement, is something we said that does not match the real world when we check.

Example: "Cats have ten legs." Go look at a cat — nope, no ten legs! That does not match reality, so it's false.

🤔 Opinion

An opinion is something we said that we can't check yet — maybe it's a feeling, or maybe it's about something that hasn't happened.

Example: "Chocolate ice cream is the best flavor." That's just how someone feels — it isn't true or false, it's an opinion. So is "Our team will win tomorrow's game" — the game hasn't happened yet, so nobody can check it!

Here's a big idea: just because a grown-up, a teacher, or someone famous says something, that doesn't make it true all by itself. We should always ask: "Does this match the real world?" That's how we check, not just who said it.

One more surprise: being true and being kind are two different things! A statement can be true and still be about something sad. And someone can say something false while still trying to be nice. Truth just tells us if words match the world — it doesn't tell us if something is good or kind. That's a different, important question all on its own — one about how we treat each other. So being honest matters, and so does being kind — we need both!

🎯 Try It Yourself!

Read each sentence below and tap what you think it is: Truth, Lie, or Opinion.

1. "A week has seven days."

That's right! A week really does have seven days — we can check a calendar. That matches reality, so it's true.

2. "Fish can fly like birds."

That's right! Fish swim, they don't fly like birds. That does not match reality, so it's false.

3. "Puppies are the cutest animals."

That's right! Cuteness is a feeling — different people feel differently. It's an opinion, not something we can check.

4. "It will be sunny tomorrow."

That's right! Tomorrow hasn't happened yet, so we can't check it. It's an opinion (or a guess) until tomorrow comes.

Next time someone tells you something, try asking yourself: is this a truth, a lie, or just an opinion? Learning to notice the difference is one of the best thinking skills you can grow. 🌱
