Decoding Writing Prompts

Overview

Lesson 13 of 20 in Literacy Skills for CAAs. Students learn to unpack writing prompts by identifying the topic, purpose, audience, form, key instruction words and evidence required. They apply a repeatable planning process to several realistic CAA-style prompts.

Learning intentions

• WALT identify the essential parts of a writing prompt.
• WALT explain how instruction words shape a written response.
• WALT distinguish between purpose, audience, form and content.
• WALT create a focused plan that responds directly to a prompt.

Success criteria

• I can highlight the important words in a writing prompt.
• I can explain what the prompt is asking me to do.
• I can identify the purpose, audience, form and key content.
• I can produce a brief plan that clearly matches the prompt.

Curriculum links

• Writing to communicate ideas clearly for a specific purpose and audience.
• Reading and viewing: interpreting, analysing and responding to texts and task instructions.
• Developing control over language features, structure and organisation.
• Key competencies: managing self; thinking; using language, symbols and texts; participating and contributing.
• Preparation for NCEA literacy writing tasks, including selecting relevant ideas and shaping writing for a clear purpose and audience.

Lesson structure (60 minutes)

1. 0–5 minutes – Hook: What does “write about” really mean? Open with the prompt-decoding introduction slides. Display two prompts: “Write about a memorable event” and “Write a formal email to the principal persuading them to improve lunchtime activities.” Students briefly discuss how the expected responses would differ. Emphasise that successful writers respond to the whole prompt, not just one interesting word.

2. 5–15 minutes – Teach the prompt code Use the prompt-decoding introduction slides to introduce the six-part prompt code: topic, instruction, purpose, audience, form and content requirements. Model the process with a prompt such as: “Write a persuasive article for the school website arguing whether students should have a later start time. Include two reasons and respond to one opposing view.” Think aloud while identifying each part and explain words such as describe, explain, persuade, compare and justify.

3. 15–22 minutes – Teacher modelling and checking Continue with the prompt-decoding introduction slides. Highlight the model prompt in different colours and build a quick plan: viewpoint, reason one, reason two, opposing view and conclusion. Ask students to identify what would make an answer incomplete, such as writing a narrative instead of an article or forgetting the intended audience.

4. 22–38 minutes – Pair prompt detectives Distribute the writing prompt analysis worksheet to pairs. Students analyse three varied CAA-style prompts, identifying the six parts and underlining instruction words. They then write one sentence explaining what each response must achieve. Circulate and ask: “Who are you writing for?”, “What form is required?” and “Which ideas must be included?”

5. 38–48 minutes – Compare and improve Students compare their responses with another pair. Display the prompts again using the prompt-decoding introduction slides and invite pairs to justify different interpretations. As a class, correct common misunderstandings, particularly confusing topic with purpose or treating a suggested idea as the entire task.

6. 48–56 minutes – Independent transfer task Students choose one new prompt from the writing prompt analysis worksheet and independently complete a six-part breakdown followed by a four-point plan. They should include a possible opening sentence and at least two relevant ideas. This provides evidence that they can transfer the process without peer support.

7. 56–60 minutes – Plenary and exit response Use the prompt-decoding introduction slides for the final reflection. Students complete the sentence: “Before I start writing, I will always check…” and name one instruction word whose meaning they can now explain. Collect the independent breakdowns for formative assessment and preview that the next lesson will turn a decoded prompt into a structured draft.

Resources

• the prompt-decoding introduction slides
• the writing prompt analysis worksheet
• Whiteboard or projector
• Highlighters in at least three colours
• Pens or pencils
• Timer
• Exercise books or writing paper

Assessment

• During pair work, listen for accurate identification of purpose, audience, form and instruction words; question students who identify only the topic.
• Check the independent six-part breakdown and plan for direct alignment with the selected prompt.
• Use the exit response to identify students who need further teaching on instruction words or audience and purpose.

Differentiation

• Provide a prompt code card or colour key for students who need support, and pre-highlight one example prompt before they begin.
• Pair students strategically and provide sentence frames such as “The writer must…”, “The audience is…”, and “The purpose is to…”.
• For EAL learners, clarify instruction words with simple definitions and examples; allow oral rehearsal before writing.
• Extend confident students by asking them to rewrite one prompt for a different audience or form and explain how the expectations change.
• Allow students with literacy or processing needs extra time, enlarged text, reduced copying and the option to give their explanation orally before recording it.
