- Priorities should be set fairly.
Words to know
a good that one person buys and uses, and others cannot use at the same time
a good that benefits many people and is difficult to limit to those who pay
a person who benefits from something without sharing in its cost
a service provided by or for the community, such as a school or clinic
1. Discover: The street light
Mr Cole tells a made-up story. On a dark road, one shopkeeper puts up a lamp. Everyone who walks by benefits, even those who did not pay. “No one can easily be stopped from seeing the light,” he says. “That is why street lighting is usually a public good, paid for through taxes or community funds. If everybody waited for others to pay, no lamps would be built. Those who benefit without contributing are called free riders.” Roads, public health campaigns and courts work similarly.
Think: What other service in your community benefits everyone?
2. Understand: Public goods and services
Idea 1: Private and public
A private good is bought and used by one person, like a snack. A public good benefits many people and is hard to limit to those who pay, like street lighting, clean air or public health campaigns. A public service is provided by or for the community, such as schools, clinics and courts.
Idea 2: Why collective provision?
If each person waits for others to pay, the good may not be provided: the free rider problem. Governments and communities therefore raise funds, often through taxes or contributions, to provide roads, schools, water systems and defence. Some services also use partnerships with private groups or charities.
Idea 3: Setting priorities fairly
Because resources are scarce, communities must choose priorities: which road to repair, which clinic to build, which school to equip. Fair decisions use clear criteria, evidence of need, public information and a chance for people to be heard.
3. Worked examples
Example 1 (I show you): Define
Public good.
- Think.
- Say.
- Check.
Answer: Benefits many people.
Example 2 (We do it together): Define
Free rider.
- Think.
- Say.
- Check.
Answer: Benefits without contributing.
Example 3 (You try): Name
A public service.
Show the steps and answer
- Think.
- Say.
- Check.
Answer: A school.
Did you know?
Many countries run national vaccination campaigns because a protected community benefits everyone.
Why this matters
Understanding public goods shows why we share costs for things everyone needs.
4. Explore: Community priorities
Read a made-up town budget with tokens for a road, a clinic, a school and a street light. In groups, set criteria for fairness, rank the projects with reasons, and compare rankings across groups.
- Read.
- Set criteria.
- Rank.
- Compare.
Think about it: what did you notice?
What did you notice? Fair criteria help groups agree.

If a learner struggles
- Find the misconception: “Everyone uses public goods so nobody should pay.” Costs are shared.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a public goods 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 studies public goods and services using a made-up town. Please talk about shared services. You do not need to be an expert to help.
- Name public services.
- Discuss fairness.
- Avoid party talk.
- 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 public good, private good, public service, free rider; explain why some goods are provided collectively; describe who provides them; discuss fair priority-setting.
Prerequisite knowledge. Grade 6 ideas: scarcity, opportunity cost, production and consumption, markets and prices, specialisation and trade.
Materials. Budget cards. 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 budget cards.
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 street light story.
Explanation (10 min). Teach public goods.
Guided activity (10 min). Community priorities.
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 do communities provide some goods together?
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. “Everyone uses public goods so nobody should pay.” Costs are shared.
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 public goods 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.
