Lesson Breakdown

1. Introduction & Review (7 minutes)

• Objective: Activate prior knowledge and clarify expectations.
• Brief recap of previous lessons focusing on Harriet Tubman’s story and author intentions.
• Teacher models a strong thesis statement based on these lessons (e.g., “Harriet Tubman’s courage and strategic intelligence demonstrate how she became a pivotal voice for freedom.”)
• Discuss what makes a thesis strong, clear, and arguable.

2. Thesis Development and Essay Planning (10 minutes)

• Objective: Students create thesis statements and organize arguments visually.
• Students individually write their thesis statements responding to: “Why is Harriet Tubman considered a key voice of freedom?”
• Distribute the graphic organizer: students map out 3 main arguments and cite 1-2 pieces of evidence from texts per argument.
• Teacher circulates, provides immediate feedback and prompts deeper thinking (e.g., “Is this evidence directly supporting your point?”).

3. Drafting the Argumentative Essay (15 minutes)

• Objective: Students write a focused, structured essay draft using their graphic organizer.
• Students write a concise intro paragraph (with thesis), body paragraphs (with evidence), and conclusion.
• Remind students to use linking phrases (e.g., “Firstly,” “Moreover,” “In conclusion”) to improve flow.
• Encourage clarity and argument-focused sentences.

4. Peer Review & Feedback (10 minutes)

• Objective: Apply critical reading and constructive feedback skills.
• Pair students and exchange drafts. Each student uses the peer review checklist to:
  • Identify thesis clarity
  • Evaluate strength/relevance of arguments and evidence
  • Suggest improvements for organization and clarity
• Students discuss their feedback politely and specifically.
• Teacher facilitates and guides feedback conversations to keep them positive and productive.

5. Wrap-Up and Reflection (3 minutes)

• Objective: Consolidate learning and set goals for revision.
• Brief class discussion: “What was challenging about crafting your argument?” and “How did peer feedback help you?”
• Homework prompt: Revise their essay draft using peer feedback, focusing on strengthening thesis support and clarity.

Assessment

• Formative assessment through:
  • Thesis statement task
  • Completed graphic organizer

Differentiation and Extensions

• For learners needing extra support:
  • Provide sentence starters for thesis and evidence integration (e.g., “I believe…, because…”).
  • Use a partially completed graphic organizer for scaffolding.
• For advanced learners:
  • Challenge to incorporate counterarguments and rebuttals in their essays.
  • Encourage using a broader range of rhetorical devices studied in prior lessons.
