Tutoring abilities

Imagine you want your school principal to make recess fifteen minutes longer.

To convince them, telling a funny story or listing the playground rules won't work — you need **opinion writing** to make your case.

Before you can persuade anyone, how do you tell the difference between a simple fact and an opinion?

A **fact** is a statement that can be proven true or false using evidence, observations, or tests.

An **opinion** is a personal belief, feeling, or thought that people can agree or disagree with.

Now that you can spot an opinion, how does an author turn that opinion into a complete piece of writing?

Writers choose their writing style based on their **author's purpose**, which is the main goal of their piece.

The three main types are **narrative writing**, **informative writing**, and **opinion writing**.

What makes an opinion piece strong enough to actually change someone's mind?

Just shouting your preference isn't enough — an opinion piece requires a clear **point of view** supported by solid **reasons**.

A common mistake is thinking an opinion is just an emotional guess, but strong writers support their opinion with real evidence and facts.

Whenever you read an article, ask yourself: is the author telling you a story, teaching you facts, or trying to convince you to agree with them?

Understanding What Opinion Writing Is. Explain what opinion writing is and how it is different from informative and narrative writing.

KS2 English: What is Persuasive Writing and How Does it Differ from Information Texts?

Developing Evidence-Based Opinion Writing in the Elementary Classroom

When introducing 4th graders to opinion writing under standard W.4.1, start by establishing the 'Purpose Triad' (Persuade, Inform, Entertain). Use short, high-interest mentor texts on familiar topics (e.g., school uniforms, pets, screen time) where students examine three different texts on the same subject to see how each genre approaches it differently. Emphasize early that an opinion is not just a preference, but an argument supported by reasons ('why') and evidence ('proof').
