Duration: 30 minutes
Number of Students: 26
Unit: Explaining the World (Lesson 2 of 5)
Subject: English Language

Learning Objectives

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

1. Identify the three key components of an explanation text: introduction, body, and conclusion.
2. Understand the purpose of each component in helping readers understand the explanation.
3. Break down a simple explanation text into its key parts.
4. Collaborate with peers to analyse and discuss how each part contributes to the explanation.

---

Success Criteria

Students can:

• Point to the introduction, body, and conclusion in a sample explanation text.
• Explain in their own words what each part does.
• Confidently talk with a partner or group about the structure of an explanation.

---

Materials Needed

• Printed sample explanation texts (one per pair of students) on everyday topics (e.g., "How a Seed Grows") written in age-appropriate language.
• Coloured highlighters or markers — 3 colours per pair.
• Whiteboard or flip chart and markers.
• Student notebooks or scrap paper.
• A large graphic organiser poster or slide showing a simple diagram of an explanation’s structure (introduction, body, conclusion).

Lesson Structure

1. Warm-Up & Activation (5 minutes)

• Begin with a brief interactive question: “Can anyone explain how something works or why something happens?” Invite 2-3 brief student answers to activate prior knowledge.
• Introduce today’s focus: “Today, we are detectives! We will look closely at explanation texts to find their important parts: the introduction, body, and conclusion.”
• Display the graphic organiser of explanation components with brief descriptions:
  • Introduction: tells what we will learn about
  • Body: explains the details or steps
  • Conclusion: sums it up

---

2. Guided Exploration (10 minutes)

• Hand out the sample explanation texts in pairs (13 pairs total).
• Instruct students to read through the text quietly together.
• Give each pair three different coloured highlighters.
• Direct pairs to:
  • Highlight the introduction with colour 1.
  • Highlight the body with colour 2.
  • Highlight the conclusion with colour 3.
• Circulate and support as students work, asking prompting questions: “How do you know this is the introduction?”, “What is this part telling us?”

---

3. Class Discussion & Analysis (8 minutes)

• Bring the class back together.
• Select a pair volunteer to share their highlighted text.
• Write their answers on the board or flipchart under headings Introduction, Body, Conclusion.
• Discuss:
  • Why is the introduction important?
  • What kind of information is in the body?
  • How does the conclusion help the reader?
• Emphasise that all parts work together to help explain clearly.

---

4. Independent Application (5 minutes)

• In their notebooks, ask students to write one or two sentences labelling and describing the parts of the explanation text they read.
• Example prompt: “In the introduction, I learned _______. The body explained _______. The conclusion told me _______.”

---

5. Wrap-up & Reflection (2 minutes)

• Ask students to turn and talk with a neighbour: “Can you tell your partner why explanations have different parts?”
• Quick round of a few responses from the class.
• Praise efforts and excitement for next lesson’s focus (writing their own explanations).

---

Assessment & Differentiation

• Formative: Teacher observation during pair work and discussion.
• Differentiation:
  • Support: Provide simpler texts with fewer sentences.
  • Extension: Challenge some pairs to identify signal words in each part (e.g., “First,” “To finish,” “In conclusion”).

---

Additional Teacher Notes

• Encourage expressive reading of explanation texts during demonstration.
• Use positive reinforcement to build confidence in identifying text structure.
• Link back to speaking and listening skills by encouraging students to explain their thinking clearly.
• This lesson supports multiple literacy strands of the Irish primary curriculum (oral language, reading, writing).

This approach “wow” factor:

• Turn students into ‘text detectives’ with colour-coded evidence collection.
• Multi-sensory (visual + verbal + kinesthetic) engagement.
• Peer collaboration supported by playful and purposeful highlighting.
• Clear connection to real-world skills — breaking down information helps them understand everything better!
