Objectives

• Analyse how Duffy uses the extended onion metaphor to redefine love across the whole poem, citing specific lines.
• Explain how structural choices — including the isolated single-word line 'Lethal' and the volta after 'I am trying to be truthful' — create a shift in tone.
• Identify and interpret the connotations of specific diction choices, including 'platinum loops,' 'possessive,' and 'cling,' in the context of love and power.
• Write an evidenced analytical paragraph that embeds relevant context about the commercialisation of Valentine's Day and Duffy's challenge to romantic convention.
• Compare Duffy's presentation of love in 'Valentine' with at least one other poem or text, supporting claims with close textual reference.

The sequence

1. Lesson 1: The Honest Onion: Close Reading Duffy's Central Metaphor

   55 min · ch. 1

   Do now

   Write down one gift you would give to someone you love and one word that captures what love feels like at its worst. Make sure to keep both answers. You’ll need them when we read the poem — no looking anything up.

   Teacher input

   Model the extended metaphor by reading aloud lines 1–9 ('Not a red rose or a satin heart… It will blind you with tears / like a lover'). On the board, annotate 'a moon wrapped in brown paper': illustrate how 'moon' suggests romance and light, while 'brown paper' takes away from that — the gift feels ordinary, genuine, and domestic. Next, explore how the same onion produces conflicting ideas (light / tears, unveiling / blindness) within nine lines, showing that Duffy creates a metaphor that captures both the beauty and pain of love at the same time instead of selecting one.

   Independent task

   Choose ONE image from the second half of the poem — either _“Its platinum loops shrink to a wedding ring”_ or _“Its scent will cling to your fingers, / cling to your knife”_ — and write a complete PEEL paragraph (8–12 sentences) that explains the literal meaning of the image, what it suggests about love's possessiveness or danger, and how Duffy's word choices (including _“cling,” “knife,”_ or _“platinum”_) shape the reader's response. Underline every quotation you use.

   In two sentences, explain why Duffy ends the poem on the single isolated word 'Lethal' rather than incorporating it into the previous line — what effect does that structural choice create for the reader?

2. Lesson 2: Love as Danger: Writing a Contextualised Exam Response

   55 min · ch. 1

   Do now

   Read the final six lines of the poem again ('I give you an onion… Lethal'). Without referring to your notes, write one sentence expressing your thoughts on Duffy's attitude toward romantic love, and another sentence discussing the real-world context that may have influenced her to write this poem in 1993.

   Teacher input

   Duffy presents love as something that commercial culture has falsified. In the opening lines, “Not a red rose or a satin heart,” she deliberately rejects traditional symbols of love, suggesting that these images are mere products of mass production. The phrase “satin heart” evokes a synthetic material, highlighting its artificiality and hollowness, which reflects how consumerism distorts genuine emotion. This is particularly relevant considering that the greeting-card industry's imagery for Valentine's Day was at its commercial peak in the 1990s, illustrating how the context of consumer culture enhances our understanding of Duffy's critique rather than overshadowing it.

   Independent task

   Write a full exam-style response of three to four paragraphs (around 350–450 words) to the question: 'How does Duffy present love as both desirable and dangerous in "Valentine"?'. Be sure to refer to at least three specific moments in the poem — the opening refusal ('Not a red rose or a satin heart'), the central metaphor of the onion's kiss ('Its fierce kiss will stay on your lips'), and the closing lines ('Its scent will cling to your fingers, / cling to your knife'). Additionally, include a reference to relevant context regarding Duffy's challenge to traditional romantic or gender norms.

   Write one sentence identifying the strongest piece of evidence you used in your response today and one sentence explaining what you would change or add if you had ten more minutes.

Activities

Assessment

• Lesson 1 do-now responses reveal whether students already associate love with negative emotions, giving the teacher a baseline before the poem is introduced.
• Whole-class feedback from the Metaphor Mapping activity shows whether groups can distinguish the literal vehicle (onion) from the tenor (love) and track how the metaphor darkens.
• The Tone Shift Tracking sheet checks whether individual students can name specific structural features — the isolated line, the volta — rather than describing tone in vague terms.
• The Lesson 1 exit ticket assesses whether students understand that the isolated word 'Lethal' is a deliberate structural choice with a specific tonal effect, not merely a dramatic flourish.
• The Lesson 2 do-now sentence on context reveals how much students already know about Duffy's 1993 cultural moment before the teacher models contextualised writing.
• Peer-marking in the Comparative Quick-Write shows whether students can apply the three analytical criteria (argument, embedded quotation, genuine difference) to someone else's work before submitting their own.

Standards covered

Common Core 11 12

• RL.11-12.1 — cite strong and thorough textual evidence to support analysis of what the text says explicitly as well as inferences drawn from the text.
• RL.11-12.4 — determine the meaning of words and phrases as they are used in the text, including figurative and connotative meanings; analyse the impact of specific word choices on meaning and tone.
• RL.11-12.5 — analyse how an author's choices concerning how to structure specific parts of a text contribute to its overall structure and meaning as well as its aesthetic impact.
• W.11-12.1 — write arguments to support claims in an analysis of substantive topics or texts, using valid reasoning and relevant and sufficient evidence.

AP Literature

• Literary Argumentation (Skill 1.A) — make a defensible claim that requires literary analysis of a poem.
• Explain the function of figurative language (Skill 3.B) — explain how Duffy's extended onion metaphor contributes to the poem's meaning.
• Explain the function of structure (Skill 3.D) — analyse how the isolated line 'Lethal' and the volta after 'I am trying to be truthful' shape the reader's experience.
• Use evidence to support a line of reasoning (Skill 7.C) — select and embed quotations that directly support the analytical argument rather than merely illustrating it.

AQA

Eduqas
