Lesson Overview

In this lesson, students will construct and install doors and windows for their Mai Mai (duck blind) project. The focus will be on ensuring the functionality and aesthetic value of these elements while reinforcing practical construction skills and connections to New Zealand’s outdoor culture.

---

Learning Outcomes

By the end of the lesson, students will:

1. Understand the role of doors and windows in usability, ventilation, and camouflage.
2. Apply measuring, cutting, and assembling techniques to create suitable doors and window frames.
3. Evaluate installation success using durability and functionality checks.

Lesson Breakdown (60 minutes)

1. Introduction & Context (10 minutes)

• Quick recap (5 min):
  • Revisit last lesson’s progress.
  • Discuss the importance of installation accuracy.
• New learning focus (5 min):
  • Show sample doors/windows (if available).
  • Class brainstorm: What makes a door or window effective in a Mai Mai? (Discussion on security, usability, camouflage, and durability).

2. Guided Construction (20 minutes)

• Step 1: Measuring and Marking (5 min)
  • Students mark out door and window dimensions on pre-cut timber according to their design plans.
• Step 2: Cutting & Smoothing (5 min)
  • Using jigsaws or hand saws (with supervision), students cut the necessary supports and frame pieces.
  • They sand edges for a clean finish.
• Step 3: Frame Assembly (5 min)
  • Attaching hinges to door frames.
  • Reinforcing with screws to ensure durability.
• Step 4: Window Installation (5 min)
  • Attaching Perspex/mesh for visibility and protection.
  • Ensuring a snug, waterproof fit.

3. Testing & Adjustments (15 minutes)

• Functional testing (5 min)
  • Each pair/group tests their door and window for ease of movement, fit, and structural integrity.
• Peer review & small fixes (10 min)
  • Partners assess each other’s work against design specifications.
  • Minor fixes (tightening screws, sanding edges for smooth closing/opening).

4. Reflection & Wrap-up (15 minutes)

• Group discussion (5 min)
  • What worked well?
  • What could be adjusted in future builds?
• Connection to real-world applications (5 min)
  • Discuss how similar considerations (insulation, security, aesthetic) apply in home construction.
• Next steps (5 min)
  • Preview next lesson: Weatherproofing and finalising aesthetic details.

Assessment Opportunities

Formative:

• Observation during measuring and assembly.
• Peer feedback in testing phase.

Summative:

• Completed door and window meeting brief specifications.

---

Differentiation & Extensions

• Support:
  • Students needing assistance can use pre-cut frames for assembly practice.
• Extension:
  • Encourage advanced students to add locking mechanisms or weatherproofing features.

---

Māori and Sustainability Integration

• Mātauranga Māori:
  • Discuss traditional Māori shelter designs (whare raupō) and how ventilation and insulation were considered.
• Sustainability Considerations:
  • Encourage discussion on using repurposed materials and minimising waste.

Teacher Reflection

• Did students engage with the practical steps effectively?
• Were there common issues that need to be revisited next lesson?
• Were students able to connect their work to real-world applications?

This structured, hands-on lesson ensures meaningful student engagement and aligns with the New Zealand Curriculum (Technology, Level 6).
