Trade-offs & Choices
The Art of Decision Making Under Scarcity
📚 Learning Intentions
- Define "Trade-off" and "Opportunity Cost" in a survival context.
- Analyze the consequences of forced choices between competing essentials (Water, Food, Shelter).
- Model household budgeting decisions when resources are severely restricted.
✅ Success Criteria
- I can identify the opportunity cost of three different spending decisions.
- I can create a survival budget that prioritizes long-term health over short-term wants.
- I can explain the reasoning behind a difficult decision made in a disaster scenario.
👩🏫 Teaching Instructions
Focus on the 'hidden cost'. Students often focus on what they *get*; this lesson forces them to focus on what they *lose* by making a specific choice.
Scenario: "I have 10 hours. I can study for a test or play games. I cannot do both." surfaced the concept of limited time as a resource.
Run the Budgeting Task. Force a price hike halfway through (Inflation spike) to simulate real-world economic shocks.
Debrief the Role-Play. Ask: "If someone else made the choice for you, is it still a trade-off? How does this connect to power?"
🚀 Haerenga Ako (Lesson Flow)
1. Role-Play: The Survival Choice
Groups use the Scenario Cards to decide how to allocate the final remaining crates of relief supplies. Each choice leaves one group in need.
2. Numeracy: Survival Budgeting
Completing the Budgeting Task. Students must feed a whānau of five on a severely restricted weekly budget.
Kaiako Moves
- Ask: What is the emotional cost of having to choose between medicine and healthy kai?
3. Reflection: The Cost of Choosing
Guided writing using the Reflection Prompt. Focus on defining the opportunity cost of their specific budget decisions.
🎯 Tahua Aromatawai (Assessment)
Mātainuku Evidence

- Written explanation of the opportunity cost of one specific trade-off.
Mātairea Support
- In-class debate on the 'fairest' way to distribute scarce resources.

📋 Teacher Planning Snapshot
Ngā Whāinga Ako — Learning Intentions
Students will engage with this resource to investigate the intersection of kai (food), culture, and climate — exploring how mātauranga Māori approaches to food production, preservation, and distribution offer powerful responses to contemporary food security and climate challenges in Aotearoa New Zealand and globally.
Ngā Paearu Angitū — Success Criteria
- ✅ Students can explain how traditional Māori kai practices (maramataka, kūmara cultivation, rāhui) embody ecological knowledge and food security principles.
- ✅ Students can connect kai culture and climate scarcity to contemporary community action and food sovereignty movements.
Differentiation & Inclusion
Scaffold support: Provide graphic organisers that map traditional kai practices to modern food security concepts at the entry level. Offer extension tasks asking students to research a specific iwi's traditional food system and evaluate its contemporary relevance, or to investigate a local food sovereignty initiative.
ELL / ESOL: Pre-teach domain vocabulary (food sovereignty, food security, kaitiakitanga, rāhui, maramataka) using visual diagrams and real-world examples. Draw connections to students' own cultural food traditions — these are valid entry points into the unit's themes. Allow oral or visual presentation of learning as alternatives to written tasks.
Inclusion: Kai is a universal human experience — all students have a relationship with food, seasonality, and sharing. Neurodiverse learners benefit from concrete, hands-on engagement with these concepts (e.g., examining a kūmara, mapping seasonal foods). Acknowledge diverse economic circumstances sensitively when discussing food security. Choice in how students demonstrate understanding (written, visual, oral) supports inclusive assessment.
Mātauranga Māori lens: The maramataka — the Māori lunar calendar — is one of Aotearoa's most sophisticated environmental data systems, encoding centuries of ecological observation about planting, harvesting, fishing, and weather patterns. Kūmara cultivation in pre-colonial Aotearoa was a feat of agricultural knowledge adapted to a new climate. Rāhui (temporary resource restrictions) is indigenous resource management — conservation before conservation. Kaitiakitanga frames the relationship between people and kai not as extraction but as reciprocal guardianship. These are not historical curiosities — they are living solutions to contemporary problems.
Prior knowledge: Students benefit from foundational understanding of climate change and food systems. No specialist mātauranga Māori knowledge required for entry-level engagement — the unit builds this knowledge progressively.
Curriculum alignment
- Place and Environment — Social Studies: Understand how people's management of resources reflects their values and their view of sustainability — and how mātauranga Māori frameworks provide models for sustainable resource management.
- Ecology — Living World: Understand how human activities and natural factors affect the distribution and abundance of organisms; evaluate the impact of changes on ecosystem health and food systems.
