The lesson

Warm-up — which order?

5 min
  1. Give three reasons for one opinion. Put them in order of strength.
  2. Ask whether the strongest goes first or last.

Teach — order is an argument

13 min
  1. Write the opinion and three reasons in note form.
  2. Order them: strongest last, so the piece builds.
  3. Write reason one as a paragraph with a linking word and an example.
  4. Show what happens with the strongest first: the piece deflates.
  5. Write the conclusion, naming the reasons rather than repeating the opinion.
“Put your best reason last. The reader should finish more convinced than they started.”

Guided practice — plan the order

12 min
  1. Students plan three reasons and rank them.
  2. A partner checks the ranking makes sense.
  3. They draft the first two paragraphs.

Independent practice

8 min
  1. Students complete the opinion writing page.
  2. The prompt and a planning grid are on the sheet.

Close

2 min
  1. Read one plan's reason order and say why it builds.

What goes wrong, and why

Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.

Writes reasons in the order they were thought of.

Why: That is the order they arrived, and no other order was considered.

Fix: Rank before drafting. The ranking is a separate decision from the generating.

Three reasons that are one reason split three ways.

Why: One strongly held reason produces the most to say.

Fix: Partner check at the note stage. Overlap is visible in notes and invisible in paragraphs.

The conclusion is the introduction reworded.

Why: Both state the opinion.

Fix: The conclusion names the reasons; the introduction does not. That is what distinguishes them.

If they are not there yet

  • Two reasons rather than three.
  • Give the ranking.

If they finish early

  • Acknowledge a reason against and answer it.
  • Write for a reader who disagrees.
  • Reorder the reasons and say what changed.

Exit ticket

List your three reasons in order and say why that is the order.

What to look for: A reason for the order. 'That is how I thought of them' means the ranking step needs to be separate.

Three, each a reasoning error rather than carelessness: writes reasons in the order they were thought of; three reasons that are one reason split three ways and the conclusion is the introduction reworded. The plan gives the thinking behind each one and the teaching move that addresses the thinking rather than the symptom.

How do I know whether the lesson worked?

The exit ticket asks: “List your three reasons in order and say why that is the order.” A reason for the order. 'That is how I thought of them' means the ranking step needs to be separate. That tells you whether the class needs a reteach or a thirty-second conversation before you plan tomorrow.
