Designing Stable Towers

Overview

This 120-minute hands-on lesson will engage Years 4-6 students in exploring strength and stability in structures using everyday materials. Students will work collaboratively, building towers from cardboard and hot glue, then critically evaluate their designs. The lesson aligns specifically with Te Marautanga o Aotearoa (the Māori-medium curriculum framework) and integrates relevant technology learning objectives, mathematical spatial reasoning, and key competencies to support your bilingual, diverse rural classroom with high learning needs.

Learning Objectives (WALT = We Are Learning To)

Investigate and understand the concept of stability in physical structures using everyday materials.
Collaborate effectively in small groups to design, assemble, and test sturdy towers.
Critically evaluate and reflect on the strengths and weaknesses of their own constructions.
Use te reo Māori to describe their design process and findings.
Develop problem-solving, creativity, communication, and critical thinking skills.

Success Criteria

Students work in groups of 3-4 to build the tallest and most stable tower using cardboard and hot glue.
Students assess their tower’s stability by observing wobbling, leaning, and ability to support weight.
Students articulate strengths and areas for improvement in their design, using appropriate technical vocabulary, in both English and te reo Māori.
Students follow safety protocols when using hot glue and other tools.

Curriculum Alignment: Te Marautanga o Aotearoa

Technology Learning Area

Whāinga Ako | Learning Intentions:

Manawanui (perseverance): persistence in problem-solving.
Wānanga (critical thinking): analyzing and reflecting on outcomes.
Te Reo Māori me ōna tikanga: using language in real contexts, supporting bilingual learning.

Mathematics Integration

Develop spatial reasoning by building 3D structures and understanding geometric forms.
Use measurement and estimation informally when comparing heights and stability.

Key Competencies

Managing Self: organising tasks and tools safely.
Relating to Others: working collaboratively.
Thinking: evaluating design effectiveness.
Using Language, Symbols and Text: explaining ideas and results.

Lesson Plan Breakdown (120 minutes for 22-25 students)

Time	Activity	Details/Resources
0-15 min	Introduction & WALT explanation	In te reo Māori and English - explain what stability means, show short demonstration of leaning vs stable towers, discuss success criteria.
15-30 min	Brainstorm & Design sketch (in groups)	Students discuss and draw simple designs for their towers, naming parts in te reo Māori. Use large paper, pencils, and vocabulary cards (e.g., "pou" - post, "turanga" - base).
30-50 min	Gather materials & safety briefing	Distribute cardboard, scissors, rulers, and hot glue guns with safety instructions & adult supervision emphasized.
50-95 min	Building towers	Students build towers in their groups. Teacher circulates to prompt questioning, scaffolding, and language support. Encourage testing stability as they build.
95-110 min	Testing & Evaluating	Groups test their towers’ stability by gently shaking or adding small weights (e.g., cubes). Discuss what makes some towers more stable. Record observations conceptually and using drawing/writing.
110-120 min	Group presentations & reflective discussion	Each group briefly explains their design choices and learning points in both languages (te reo and English). Celebrate successful strategies and learning from "failures".

Teaching and Learning Supports

Use language scaffolding: Provide bilingual word cards and sentence starters.
Visual aids of simple building blocks and Māori narrative connection to structures (e.g., whare – Māori meeting houses known for their strong structural design).
Safety is critical with hot glue: model safe use and provide supervised access.
Use flexible groupings to accommodate varying ability levels.
Encourage turn-taking and cooperative problem solving.
Frequent formative assessment conversations and scaffolding to reduce anxiety or frustration.

Assessment Opportunities

Observe collaborative participation and group dynamics (Whanaungatanga).
Use questioning to assess understanding of stability concepts and vocabulary use in both languages.
Evaluate the completed towers against the success criteria.
Review students’ design sketches and verbal explanations to assess critical thinking (Wānanga) and communication skills.
Use simple self and peer-assessment: each group notes what worked well and what to improve in next constructions.

Classroom Environment & Cultural Connections

Build knowledge around traditional Māori architecture (whare and pou) and the importance of stable structures in whakapapa and community.
Incorporate whakataukī (proverbs) related to strength and perseverance, e.g., "Nāu te rourou, nāku te rourou, ka ora ai te iwi" — by sharing resources and working together the group succeeds.
Deliver the lesson predominantly in te reo Māori, consistent with your bilingual approach, while supporting new learners' English understanding.

Reflection & Next Steps

Encourage students to set personal or group goals for their next building challenge (Lesson 4 focuses on refining structures and presentation).
Provide vocabulary review and digital storytelling (e.g., photos or video reflection) as extension activities.
Reinforce the link between everyday structures and the concepts learned.

This lesson plan is designed not only to meet the technological learning goals within Te Marautanga o Aotearoa but also to support your multi-level, bilingual classroom through language integration, hands-on learning, and cultural relevance, fostering engagement and resilience.

If you would like, I can also create bilingual key vocabulary lists or templates for evaluation forms in te reo Māori and English. Please let me know!
