Lesson Objectives

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

1. Identify key elements of BCITO Unit Standard 12936 and explain their relevance to Mai Mai construction.
2. Understand the role of building codes and standards in ensuring safe and effective structures.
3. Analyse real-world examples of compliant and non-compliant structures.
4. Collaborate in small groups to assess building plans for potential compliance issues.

Lesson Structure

1. Introduction (10 minutes)

• Engage: Show students an image of a well-built Mai Mai and a poorly constructed one. Ask:
  • “What differences can you see?”
  • “Why do you think some structures last longer than others?”
• Discussion: Briefly introduce BCITO Unit Standard 12936. Explain that in New Zealand, even structures like huts and Mai Mais need to meet certain standards. Relate this to their personal experiences—e.g., have they ever been in a building that felt unsafe or unstable?

2. Direct Instruction: Understanding BCITO Unit Standard 12936 (15 minutes)

• Key Points:

  1. Why Building Codes Matter – Ensure safety, longevity, and environmental sustainability.
  2. Key Aspects of Unit Standard 12936
     • Materials selection
     • Structural integrity
     • Weatherproofing requirements
     • Environmental considerations
  3. Compliance vs. Non-Compliance
     • Real-world consequences (e.g., structural collapse, safety hazards)
     • NZ case studies of unsafe builds

• Demonstration: Show an example of building plans and explain how they meet or fail to meet standards.

3. Interactive Activity: Code Compliance Challenge (20 minutes)

Activity Breakdown:

• Step 1: Divide students into small groups (3-4 per group).
• Step 2: Provide each group with a simplified Mai Mai building plan—some following the NZ Building Code, and some with intentional errors (e.g., incorrect material use, weak structures, lack of weather protection).
• Step 3: Groups use highlighters to identify compliance issues in the faulty plans.
• Step 4: Students present their findings to the class, explaining why the identified issues violate standards.

💡 Teacher's Role: Circulate among groups to guide discussions and encourage critical thinking.

4. Reflection and Exit Ticket (15 minutes)

• Class Discussion: Ask:
  • “What surprised you most about these building codes?”
  • “What are the biggest risks if we ignore construction standards?”
• Exit Ticket (Written Response):
  • Name one rule from BCITO Unit Standard 12936 that you didn’t know before.
  • Describe a potential consequence of violating this rule in real-world construction.

---

Assessment and Homework

✔ Formative Assessment: Group presentations and exit ticket responses.
✔ Homework: Research an example of a faulty structure (past or present) in New Zealand and prepare a brief summary on why it failed.

Teacher Notes & Differentiation

• Scaffolding: Provide visual aids and simplified versions of the building codes for students who need extra support.
• Extension Task: Encourage high-achieving students to explore sustainable building materials that comply with NZ standards.

Conclusion

By linking building codes to real-world applications, students will not only understand regulatory standards but also appreciate why they exist. Engaging discussions and hands-on analysis will cement these concepts, setting the foundation for future construction lessons.

🚀 Excited to see their problem-solving skills at work in the next lesson!
