Social Studies
Objective: I can explain scarcity and how it forces people and communities to choose.
Standards: D2.Eco.1.3-5, D2.Eco.3.3-5
Builds on: Needs Week 24 Day 4 (opportunity cost) and Day 3 (budgets). One-minute check: "You choose juice instead of milk. What is the opportunity cost?" (The milk.)
- scarcity – not having enough of something for everyone to have all they want
- Warm-Up (5 min) — Spaced review from Week 24. Ask: "What is the difference between a need and a want?" (A need is something you must have to live and be safe. A want is nice to have.) Then ask the big question: "Name five things you want. Could you buy them all today? Why not?"
- Mini-Lesson (10–15 min) — Say: "Scarcity means there is not enough of something for everyone to have all they want." "Money, time, land, water and materials are all limited." "Scarce does not mean rare, like gold. Everyday things are scarce too." Say: "We have 30 minutes before dinner. You want to draw, read and play outside for 30 minutes each." Ask: "Can you do all three?" (No.) Say: "Time is scarce, so you must choose." Say: "Scarcity makes everyone choose: people, families and whole towns." "A town has enough money this year to fix its old pool or to open the library on Sundays. It cannot do both." "Whatever the town does not choose is its opportunity cost." Ask: "Is time scarce? How do you know?" (Yes. A day has only 24 hours.) "Is a thing scarce only when it is rare?" (No. Anything limited is scarce.) "The town picks the library. What is its opportunity cost?" (Fixing the pool.) If stuck, say: "Is there enough for everyone to have all they want? If not, it is scarce."
- Activity / Source Work (15–20 min) — Part 1, a personal choice. 1) Write eight item cards with prices. Board game $12, book $6, art set $8, soccer ball $10. Puzzle $5, kite $7, headphones $15, movie ticket $9. 2) Give your child the 20 play dollars. Your child picks cards without going over $20 and pays you. 3) Your child fills a chart: Item | Price. Then write the total and the money left. 4) Ask: "Which card did you want most but could not buy?" That next-best card is the opportunity cost. Your child writes it on a sticky note. Part 2, a town's choice. 5) Read the pool or library problem again. On two sticky notes, your child lists who benefits from each choice. (Pool: swimmers and families in summer. Library: readers, students and job seekers.) 6) Your child decides, writes the choice on the last note and gives a reason. Choices vary. Look for a total of $20 or less and a named opportunity cost.
- Notebook Entry (10 min) — Your child completes: "Scarcity means ___. At home, ___ is scarce, so we ___. In a town, ___ is scarce, so leaders ___." Sample: "Scarcity means there is not enough for everyone to have all they want. At home, the bathroom is scarce in the morning, so we take turns. In a town, money is scarce, so leaders choose which projects to pay for."
- Exit Ticket (5 min) — Read each exit question aloud. Your child answers in the notebook. Praise answers that name what is limited.
Watch for: Thinking scarcity means only rare things, like gold.
Try: Use a home example. Say: "There is one last slice of pie and three people want it. That is scarcity."
- Four children want to use the one swing at the same time. What is scarce? What must they do?
- Dev has $10. A ball costs $7 and a game costs $8. Can he buy both? Which economics word explains why he must choose?
- Gold is rare. Tap water is not rare. Can clean tap water still be scarce? Tell why.
Answers: 1) The swing, or time on the swing. They must take turns or choose who goes first. 2) No. 7 + 8 = 15, and $15 is more than $10. Scarcity. 3) Yes. Clean water is limited and costs money to bring to homes, so people cannot use all they want.
