Student lesson
- Resources are limited.
- A choice means giving something up.
- We choose using criteria.
- Looking back helps us choose better.
Words to know
something we use to meet needs and wants
giving up one thing to get another
things we check before we choose
not unlimited
1. Discover: The class garden
The class has enough money for either seeds or a watering can, not both. Kofi wants seeds. Amara wants the watering can. Ms Smith asks, “What do we check? Can we borrow a can? Can we get seeds free?” After talking, they decide to borrow a can from the caretaker and buy seeds. “We gave up the new can,” says Amara, “but we saved money for seeds.”
Think: What did the class give up?
2. Understand: Choices
Idea 1: Limited resources
A resource is anything we use to meet needs and wants: money, time, materials, energy and people’s skills. Resources are limited, so we cannot do or buy everything.
Idea 2: Trade-offs
A trade-off means giving up one thing to get another. If we spend time playing, we have less time for homework. If we spend money on books, we have less for sweets. Looking at what we give up helps us choose wisely.
Idea 3: Choosing well
To choose well, set criteria such as need, cost, safety and how long it will last. Then compare choices, choose, and look back to see whether it worked. Sharing and borrowing can stretch resources.
3. Worked examples
Example 1 (I show you): Spot
What is given up?
- Think.
- Find.
- Say.
Answer: The new can.
Example 2 (We do it together): Criteria
Choose seeds or can.
- List.
- Compare.
- Choose.
Answer: Need, cost, sharing.
Example 3 (You try): Reflect
Was it good?
Show the steps and answer
- Think.
- Check.
- Say.
Answer: Yes, we saved money.
Did you know?
The idea of giving up one thing to get another is so important that economists call it opportunity cost.
Why this matters
Making good choices with limited resources is a skill for life.
4. Explore: Choose and reflect
Give pairs a pretend budget for two class projects. Choose using criteria, write what is given up and reflect after.
- List.
- Compare.
- Choose.
- Reflect.
Think about it: what did you notice?
What did you notice? Every choice gave something up.

Mastery and remediation
| Objective | Bronze (Developing) | Silver (Proficient) | Gold (Advanced) |
|---|---|---|---|
| O1 Say that resources are limited | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
| O2 Explain a trade-off | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
| O3 Make a choice using criteria | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
| O4 Reflect on a choice | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |

If a learner struggles
- Find the misconception: “We can have everything.” Resources are limited.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a choice poster.
- 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 to make choices with limited resources. Please let your child plan a small pretend budget. You do not need to be an expert to help.
- Talk about choices.
- Use pretend budgets.
- Share and borrow.
- 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: say that resources are limited; explain a trade-off; make a choice using criteria; reflect on a choice.
Prerequisite knowledge. Grade 2 ideas: work, occupations, goods and services, producers and consumers.
Materials. Play money, paper. 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 class garden story.
Explanation (10 min). Teach choices.
Guided activity (10 min). Choose and reflect.
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. How do we choose with limited resources?
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. “We can have everything.” Resources are limited.
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 poster. 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.
