Rhetorical Triangle Creation

Overview

In this 45-minute lesson, 12th-grade students will explore the rhetorical triangle—ethos, pathos, and logos—and apply these rhetorical appeals to a real crime case study. The goal is for students to deepen their understanding of how rhetoric shapes arguments and narratives in true crime contexts while developing critical analysis and synthesis skills aligned to Common Core standards.

---

Learning Objectives

By the end of this lesson, students will be able to:

• Define and explain the rhetorical appeals: ethos, pathos, and logos.
• Analyze a true crime case study by identifying examples of each rhetorical appeal.
• Create a visual representation of the rhetorical triangle with specific evidence from their case study.

Common Core Standards Alignment

CCSS.ELA-LITERACY.RI.11-12.3
Analyze a complex set of ideas or sequence of events and explain how specific individuals, ideas, or events interact and develop over the course of the text.

CCSS.ELA-LITERACY.RI.11-12.8
Delineate and evaluate the reasoning in seminal U.S. texts, including the application of rhetorical appeals (ethos, pathos, logos).

CCSS.ELA-LITERACY.W.11-12.2
Write informative/explanatory texts to examine and convey complex ideas clearly, using valid reasoning and relevant evidence.

CCSS.ELA-LITERACY.SL.11-12.1
Initiate and participate effectively in a range of collaborative discussions, integrating multiple perspectives on complex topics.

Materials Needed

• Copies or digital access to a short true crime case study (teacher-selected snippets)
• Rhetorical triangle anchor chart (poster or slide)
• Graphic organizer handouts for filling in ethos, pathos, logos
• Markers, colored pencils, or digital creation tools (optional for visuals)
• Whiteboard or digital display for class discussion notes

Lesson Timeline

1. Introduction to the Rhetorical Triangle (10 minutes)

• Direct Teaching: Use a brief mini-lecture supported by an anchor chart to review definitions of ethos (credibility/trust), pathos (emotion), and logos (logic/reason).
• Engagement: Share quick examples from well-known speeches or advertisements to illustrate each appeal and ask students for additional examples to connect to prior knowledge.

2. Case Study Exploration (10 minutes)

• Distribute a short true crime case excerpt focusing on the narrative or argument presented within.
• In pairs, students read and annotate the text highlighting any sentences/examples that seem to appeal to ethos, pathos, or logos.

3. Group Visual Construction of the Rhetorical Triangle (15 minutes)

• Each pair creates a visual rhetorical triangle on their graphic organizer:
  • Label each corner (ethos, pathos, logos)
  • Provide 1-2 quotes or paraphrased examples from the case study for each appeal.
• Encourage creativity in representing the connections (e.g., colors, symbols).
• Circulate and provide scaffolding, prompting students to justify their choices based on text evidence.

4. Collaborative Sharing and Discussion (8 minutes)

• Have 3-4 pairs briefly present their rhetorical triangles to the class.
• Facilitate discussion by comparing examples and analyzing how these appeals influence perceptions of the case.
• Prompt students to critique use of rhetoric and consider its impact on audience understanding and bias.

5. Wrap-Up and Reflection (2 minutes)

• Quick written exit ticket: “Which rhetorical appeal was most persuasive in your case study and why?”
• Collect exit tickets to inform next lesson's deeper dive into rhetorical effectiveness.

Differentiation Strategies

• For advanced learners: Challenge students to identify mixed appeals within single sentences or analyze the effectiveness of appeals.
• For ELL or struggling readers: Provide annotated versions of the case study with simplified language and definitions.
• Provide sentence starters for annotations and visual organizers.

---

Assessment

• Formative assessment through annotations and graphic organizer completion.
• Informal assessment during presentations and class discussions.
• Exit ticket provides individual data on comprehension and rhetorical analysis.
