How to Teach The Argumentative Essay: A Step-by-Step Lesson Plan (Ireland, Junior Cycle)

The argumentative essay is one of the most transferable things we teach in Junior Cycle English — it underpins the discursive writing our students meet across their three years and beyond. Yet a "just write your opinion" lesson usually produces a pile of unstructured feeling. This is a full lesson walkthrough for a First-to-Third-Year class in Ireland, built the way the NCCA encourages: clear learning intentions, modelling, guided practice and a plenary that checks understanding before students leave the room.

Objectives and success criteria

Share the learning intention in student-facing language: "I can build an argument that states a position, supports it with reasons and evidence, and answers a counter-argument." Tie it explicitly to the NCCA learning outcomes for Writing, and put three success criteria on the board — a clear position, at least two developed reasons, and one acknowledged counter-point. A resource such as Writing a Comment and Argumentative Essay gives you ready models that match these criteria, so students see the target before they attempt it.

Starter (10 minutes)

Open with a low-stakes hook that forces a stance. Post a debatable statement — "Homework should be banned in First Year" — and run a four-corners activity: strongly agree to strongly disagree. Students physically commit, then justify their position to one neighbour. This surfaces the raw material of argument (claim plus reason) before any writing, and it gets reluctant writers talking.

I do — modelling the move (10 minutes)

Think aloud as you build a single paragraph on the visualiser. Narrate the decisions: "I'll state my position… now I need a reason, not just a repeat… here's my evidence… and here I'll concede the other side before knocking it down." Techniques of persuasion transfer directly from speeches, so borrow the devices catalogued in Analysing Political Speeches – Rhetoric and Stylistic Devices — the rule of three, rhetorical questions, direct address — and show students how a rhetorical move strengthens a written claim.

We do — guided practice (15 minutes)

Now build a paragraph together on a new topic. Take suggestions, but hold the standard: reject a vague reason and ask the class to sharpen it. Use a shared structure so everyone has the same scaffold:

1. Position: state your view in one clear sentence.
2. Point: give a reason that supports it.
3. Evidence: an example, fact or reference.
4. Counter and rebuttal: "Some might say… however…"
5. Link: return to the position.

You do — independent writing and plenary (15 minutes)

Students write one full paragraph on a topic of their choice from a short list, applying the structure independently while you circulate and prompt. The persuasive and dramatic techniques students meet studying texts like Shakespeare – Analysing a Drama (Macbeth) — a character arguing a case in a soliloquy — offer a rich model of rhetoric under pressure that stronger writers can imitate. Close with an exit check: students underline their position in one colour and their counter-argument in another, then swap with a partner who confirms both are present. That two-minute check tells you instantly who has met the success criteria and who needs re-teaching next lesson — useful evidence as you build towards the Classroom-Based Assessments and the JCPA.
