Words to know
not having enough resources to meet everyone’s wants
something essential for living, such as food, water, shelter and safety
something we would like to have but can live without
selecting one option from several
1. Discover: One mango, three friends
Ms Smith holds up one mango and asks, “Three friends want it. What do we do?” “Share it,” says Abu. “Toss a coin,” says Mei. “Yes, there is not enough for everyone,” says Ms Smith. “That is scarcity. Every household, business and government faces it. A school might want new books, a bigger playground and a new roof, but have money for only one. It must choose.”
Think: How would you decide fairly when there is not enough for everyone?
2. Understand: Scarcity and choice
Idea 1: Scarcity
Scarcity means there are not enough resources (money, time, materials, land) to meet everyone’s wants. It affects rich and poor, families, businesses and governments. Even when something is plentiful, our time and attention are limited.
Idea 2: Needs and wants
A need is essential for living: food, clean water, shelter, safety, health care and education. A want is something we would like but could live without, like a toy or a new game. Sometimes it is hard to tell them apart; talking together helps. Needs usually come first when resources are limited.
Idea 3: Making choices
Scarcity makes people take a choice. A thoughtful choice lists the options, thinks about benefits and costs, asks who is affected, and picks what best meets needs. A farm family might choose between buying seed and repairing a roof; a government might choose between building a bridge and a clinic.
3. Worked examples
Example 1 (I show you): Sort
Need or want: clean water.
- Think.
- Say.
- Check.
Answer: Need.
Example 2 (We do it together): Sort
Need or want: a new toy.
- Think.
- Say.
- Check.
Answer: Want.
Example 3 (You try): Define
Scarcity.
Show the steps and answer
- Think.
- Say.
- Check.
Answer: Not enough for all wants.
Did you know?
Economics is sometimes called the study of how people make choices when resources are scarce.
Why this matters
Understanding scarcity helps you make wise choices about time, money and resources.
4. Explore: Choice cards
Each group receives a pretend budget of 10 tokens and a list of 8 items with prices. Choose how to spend the tokens, sort items into needs and wants, and explain the choices. Compare with another group.
- Sort.
- Choose.
- Explain.
- Compare.
Think about it: what did you notice?
What did you notice? We could not buy everything.

Courseversity badge thresholds (overall quiz score): Gold = 90–100%; Silver = 80–89.9%; Bronze = 70–79.9%. A badge is never a full record of progress.
If a learner struggles
- Find the misconception: “Scarcity only affects poor people.” It affects everyone.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a choice chart.
- Guided practice: work through one example together and let the learner try the next one.
- Reassess: use the quiz again or the worksheet.
- Move on when the learner shows Silver-level evidence independently.
For parents and guardians
In this lesson your child learns about scarcity and choices using pretend tokens. Please talk about needs and wants. You do not need to be an expert to help.
- Talk about needs and wants.
- Make choices together.
- Praise thoughtful decisions.
- Ask “how do you know?” after each answer, and listen.
- Praise effort, not only right answers. Mistakes are how we learn.
- Ten to fifteen minutes a day is better than one long session.
Teacher package
1–5. Objectives, prerequisites, materials, preparation, duration
Lesson objectives. Learners will: define scarcity, needs, wants, choice; distinguish needs from wants; give examples of choices; make a thoughtful choice.
Prerequisite knowledge. Grade 4 ideas: scarcity, resources, production, specialisation and trade.
Materials. Item cards, tokens. Low-resource options: use chalk or charcoal on a board or wall, drawings in the sand, and objects from the classroom instead of printed materials.
Preparation. Prepare item cards and tokens.
Suggested duration. 45–60 minutes. It can be split into two shorter sessions.
6–9. Teaching procedure, explanation notes, guided and independent activities
Introduction (5 min). Tell the one mango, three friends story.
Explanation (10 min). Teach scarcity and choice.
Guided activity (10 min). Choice cards.
Independent activity (10 min). Discuss.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. Why must we make choices, and how can we choose wisely?
Teacher explanation notes. Start with a picture, story, map or local example. Then talk about what was seen, then draw and write. Always ask “how do you know?” and invite more than one view. Treat every family, culture and community with respect, and never ask learners to share private information.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use pictures, maps, real objects and short sentences, and let learners work with a partner. Let learners point, show, act or draw instead of writing. Extension. Ask learners to find a new example from their own community and explain how they know.
Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.
Misconceptions. “Scarcity only affects poor people.” It affects everyone.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 10-mark exam practice and the worksheet on this page. All answers and marking guides are in the answer sections above. Re-check every answer before use.
16–19. Remediation, enrichment, homework, teacher reflection
Remediation. Make a choice chart. Enrichment. Find one new example near your home or school, draw or write about it and explain it to someone. Homework. See above.
Teacher reflection. After teaching, record: which ideas learners understood; which misconceptions occurred; which activities worked; which learners need more practice; and what to improve next time.
