Unit 10: Kai, Culture and Climate — Surviving Scarcity

"What Will We Eat Tomorrow?" — A 9-week exploration of how people in different places and times have responded to food scarcity

Unit 10 · Week 5

⚖️ Week 5: Trade-offs & Choices (Economic Thinking)

Students deepen their understanding of economic thinking by exploring how scarcity forces trade-offs. Through role-play, budgeting, and reflection, they experience making difficult choices when resources are limited.

Focus Question

How do scarcity and trade-offs shape decisions?

🎯 Learning Intentions

  • Understand what trade-offs are and why they exist
  • Experience making choices under scarcity
  • Create and manage a budget with limited resources
  • Reflect on the reasoning behind choices

✅ Success Criteria

  • I can explain what a trade-off is
  • I can make decisions when resources are limited
  • I can create a budget that covers essentials
  • I can explain why I made my choices

📚 Curriculum Alignment

  • Social Studies: Understand economic decision-making
  • Mathematics: Budgeting and financial literacy
  • English: Write explanatory paragraphs

Ngā Mahi - Week 5 Activities

1. Role-Play: Disaster Scenario (25 mins)

Activity: Use the Trade-offs Role-Play handout. Students role-play choosing between investing in water, food, or shelter after a disaster.

  • Scenario: Natural disaster has struck, resources are limited
  • Groups must choose: invest in water, food, or shelter
  • Each choice has consequences - discuss trade-offs
  • Groups present their decisions and reasoning
  • Debrief: What trade-offs did you make? Why?

2. Numeracy: Budgeting Task (25 mins)

Activity: Use the Budgeting Task - Limited Resources handout. Students have limited $50 to cover 3 essentials.

  • Students receive a list of items with prices
  • Must choose 3 essentials within $50 budget
  • Calculate total cost and remaining money
  • Justify choices: Why these 3? What did you give up?
  • Extension: Vary the complexity (add constraints, transport costs)

3. Literacy: Choice Reflection (20 mins)

Activity: Use the Choice Reflection handout. Students write a paragraph explaining why they made their choices.

  • Reflect on the role-play and budgeting decisions
  • Write about: What trade-offs did you make? Why?
  • Connect to unit concepts: scarcity, choices, consequences
  • Share reflections in pairs or small groups

4. Video: Trade-offs & Opportunity Cost (15 mins)

Activity: Watch videos about trade-offs and economic choices.

Before, During & After Watching

Before watching: What is a trade-off? Give an example from your life.

During: Note examples of opportunity cost. How does scarcity force trade-offs?

After: Think-Pair-Share: How do trade-offs connect to food scarcity?

💡 Differentiation Strategies

  • Lower support: Provide simpler scenarios, pre-calculated options, work in pairs
  • Extension: Vary the complexity of trading (add constraints, transport costs, cultural rules)
  • Cultural connection: Discuss how whānau make financial decisions, connect to values and priorities

Curriculum Alignment — Achievement Objectives

  • Learning Areas: Social Studies (economic reasoning, opportunity cost, decision-making frameworks), Mathematics (profit/loss calculations), English (argument construction)
  • Achievement Objective: Students will understand how scarcity, trade-offs, and food systems shape human decisions and cultural practices across time and place
  • Key Competencies: Thinking, Using Language Symbols & Texts, Participating & Contributing

Inclusion & Accessibility Guidance

  • ESOL / ELL learners: Pre-teach key vocabulary before each activity. Provide visual vocabulary cards and allow responses in home language before English. Pair with a bilingual buddy where possible.
  • ADHD / neurodiverse learners: Break activities into clearly timed segments with visible countdown. Offer movement breaks between activities. Provide choice in response format (verbal, visual, written).
  • Accessibility / dyslexia: All handouts available in larger font on request. Read aloud instructions for students with reading difficulties. Accept drawn or verbal responses as alternatives to written tasks.
  • Cultural inclusion: Validate diverse food traditions as equally valid — avoid framing any culture's food practices as primitive or inferior. Connect to students' own whānau food knowledge.

🌿 Mātauranga Māori Lens — Utu me te Tika

Economic trade-offs connect deeply with mātauranga Māori through the concept of utu — reciprocity and balance. In te ao Māori, decisions are not made in isolation but in relationship with whānau, hapū, and future generations (uri whakatipu). The principle of kaitiakitanga (guardianship) asks ākonga to consider: what is the cost to whenua, wai, and tangata (land, water, people) of each economic choice? This connects Western economic thinking with tikanga-based decision frameworks — both are valid lenses for evaluating trade-offs.
