Words to know
meeting needs today without harming the future
one main part of a larger idea
one of 17 global goals adopted by the UN in 2015
someone affected by a decision
1. Discover: The school garden decision
The school wants to turn the field into a car park. The class holds a meeting. Parents want convenience, the football team wants the field, and the biology club wants a garden. “Sustainable choices consider everyone, now and later,” says Ms Anokye.
Think: Which option meets the needs of the most people over time?
2. Understand: Sustainable choices
Idea 1: Definition
Sustainable development means meeting the needs of today without making it harder for future generations to meet theirs. It balances three pillars: environment, society and economy.
Idea 2: Global goals
In 2015 all UN member states adopted 17 Sustainable Development Goals (SDGs) to be met by 2030, including ending poverty, clean water, quality education, climate action and life on land.
Idea 3: Taking part
Each stakeholder has a role: governments make laws, businesses change how they produce, communities protect resources and individuals make daily choices.
3. Worked examples
Example 1 (I show you): Match
SDG and action.
- Clean water.
- Climate action.
- Education.
Answer: Goals.
Example 2 (We do it together): Weigh
Options.
- Car park.
- Field.
- Garden.
Answer: Trade-offs.
Example 3 (You try): Plan
Action.
Show the steps and answer
- Goal.
- Steps.
- Who.
Answer: Plan.
Did you know?
The 17 SDGs include zero hunger, good health, gender equality, clean energy, and peace and justice.
Why this matters
Your generation will carry sustainable development forward, so your choices and ideas matter.
4. Explore: Decision matrix
List three options for a school issue, score each from 1 to 3 on environment, society and economy, total the scores and justify the best choice.
- Choose an issue.
- List options.
- Score.
- Justify.
Think about it: what did you notice?
What did you notice? The option with the highest total also met more stakeholder needs.

Mastery and remediation
| Objective | Bronze (Developing) | Silver (Proficient) | Gold (Advanced) |
|---|---|---|---|
| O1 Define sustainable development | 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 Link three pillars | 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 Relate to the SDGs | 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 Plan action | 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 |
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: “Sustainability is only about the environment.” Three pillars.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Plan sustainable action.
- 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 sustainable development and plans a small action. You do not need to be an expert to help.
- Choose one sustainable habit.
- Ask “Who does this help?”
- Celebrate progress.
- 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 sustainable development; link three pillars; relate to the SDGs; plan action.
Prerequisite knowledge. Grade 5 ideas: weather, water cycle, ecosystems and human impact.
Materials. Matrix sheets, SDG poster. 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. Print SDG list.
Suggested duration. 45–60 minutes. It can be split into two shorter sessions.
6–9. Teaching procedure, explanation notes, guided and independent activities

Explanation (10 min). Teach sustainable development.
Guided activity (10 min). Learners score options.
Independent activity (10 min). Learners plan.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. Who is affected? What is fair?
Teacher explanation notes. Start with real objects and safe, hands-on observation. Then talk about what was seen, then draw and write. Always say “how do you know?”. Keep to the safety notes, and use local, safe materials.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use real objects and pictures, short sentences and a partner. Let learners point, show or draw instead of writing. Extension. Ask learners to find a new example at home and explain how they know.
