Exploring Expository Writing

Objective

By the end of this 30-minute lesson, 6th grade students will be able to:

• Define expository writing and explain its purpose.
• Identify different types of expository texts (e.g., how-to, informative, comparison).
• Recognize key characteristics of expository writing that distinguish it from narrative and persuasive writing.

Standards Alignment

• CCSS.ELA-LITERACY.W.6.2: Write informative/explanatory texts to examine a topic and convey ideas, concepts, and information clearly.
• CCSS.ELA-LITERACY.RI.6.2: Determine a central idea of a text and how it is conveyed through particular details.
• CCSS.ELA-LITERACY.RI.6.5: Analyze the structure an author uses to organize a text, including how the major sections contribute to the whole.
• CCSS.ELA-LITERACY.SL.6.1: Engage effectively in collaborative discussions with diverse partners on grade 6 topics.

Lesson Breakdown (30 minutes)

1. Warm-Up & Activation – What is Writing? (5 minutes)

• Ask students: "What kinds of writing do you know?" Accept answers like stories, essays, reports, etc.
• Quickly categorize their responses into narrative, persuasive, and expository writing on the board.
• Introduce the lesson focus: Expository Writing — writing that explains or informs.

Teacher script:
"Expository writing helps readers learn or understand something new by explaining facts or ideas clearly. It’s all around us—in textbooks, instructions, news articles, and more."

2. Defining Expository Writing & Its Purpose (7 minutes)

• Show the formal definition in kid-friendly language:
  “Expository writing explains information clearly and logically to teach or inform the reader.”
• Discuss with class: Why is it important? Where do we see it in real life?
• Introduce 3 common types of expository writing:
  1. How-to (explaining steps or processes)
  2. Informative (sharing facts or information)
  3. Comparison/Contrast (explaining similarities and differences)

Activity:
Display 3 short excerpts (1 for each type) on the board/projector.
Quick read-aloud and brief class discussion identifying which type each excerpt belongs to.

3. Characteristics Exploration (10 minutes)

• In small groups (6 students per group, total 8 groups), students receive a printed short expository text.
• Task: Identify and underline or highlight key features such as:
  • Clear topic sentence
  • Supporting facts or details
  • Use of transition words (e.g., first, also, however)
  • No opinions or stories
• Each group writes one characteristic they found on chart paper or sticky notes.
• Groups share 1 key characteristic with the class; teacher records on whiteboard/chart paper under “Key Features of Expository Writing.”

4. Wrap-up & Exit Ticket (8 minutes)

• Conduct a quick group discussion reinforcing:
  • Expository writing explains and informs, not tells a story or tries to persuade.
  • It uses facts, clear structure, and transitions.
• Exit Ticket: Give each student a sticky note or quick sheet to write:
  “One important thing about expository writing is...”
  Collect and quickly scan to check understanding.

Differentiation and Engagement Tips

• Provide sentence starters or graphic organizers for students who need additional support.
• Challenge advanced learners by asking them to come up with their own short how-to topic.
• Use visuals and concrete examples to appeal to diverse learners.
• Encourage peer discussion to build oral language skills aligned with CCSS.SL.6.1.

Assessment

Formative assessment through:

• Group work product (identifying features)
• Exit ticket responses to assess understanding of lesson objectives.
