Slide Deck

My Opinion, My Proof!

What's your favorite animal? Why?

Greet students and start with a fun, engaging question to activate prior knowledge about preferences.

What's an Opinion?

An opinion is what YOU think or feel about something.

It's YOUR idea!

Examples:

  • Ice cream is the best dessert.
  • Blue is the prettiest color.

Explain that an opinion is what you think or feel about something. It's not always a fact!

Opinions Need PROOF!

Just saying something is true isn't enough.

You need to explain WHY you think that!

This 'WHY' is your PROOF or EVIDENCE.

Example:
"Ice cream is the best dessert BECAUSE it is cold and sweet."

Introduce the idea that strong opinions need reasons, or 'proof'. Use simple, relatable examples.

What's an Argumentative ECR?

ECR stands for Extended Constructed Response.

It means you write a longer answer.

An argumentative ECR is when you write down your opinion and all your proof to convince someone!

Think of it like being a detective for your own ideas!

Explain what an argumentative ECR is in simple terms. Connect it to the idea of writing down opinions and proof.

Let's Look at an Example!

Read the story about the best pet. What is the author's opinion? What is their proof?

My Opinion, My Proof Reading

Provide a clear example to model for students. This links to the reading material.

Your Turn to Argue!

Now you get to share your opinions and proof!

Think about things you like or dislike. Why do you feel that way?

Encourage students to think about how they form opinions and find reasons for them.

Reading

The Best Pet

I think dogs are the best pets you can have. They are super fun and always happy to see you!

First, dogs are great because they love to play. You can throw a ball, and they will run and bring it back. They can play fetch, go for walks, and even run around in the yard with you. This makes them really exciting to have around.

Second, dogs are also the best because they can protect you. If a stranger comes to the door, your dog might bark to let you know. They are brave and will try to keep their family safe. It feels good to have a loyal friend like that.

Finally, dogs are very friendly. They love to cuddle and be close to their owners. When you're sad, they often know and will try to make you feel better. Their wagging tails and happy barks can really brighten your day.

So, because they are playful, protective, and friendly, dogs are definitely the best pets!
