Words to know
a piece of work planned and done together
a group working together
to decide steps before doing
to think about what we learned
1. Discover: The clean school project
Class One decides to make their school clean. They draw a plan. Some children sweep, some sort waste, some water the plants and some make posters. An adult helps with sharp items. At the end they look at the clean yard and smile. “We did it together,” says Aliyu.
Think: What jobs did the class share?
2. Understand: A clean school project
Idea 1: Plan it
A project starts with a plan. We decide what to do, who does what and what we need: brooms, bins, gloves and bags. We choose a day and an adult helper.
Idea 2: Do it safely as a team
A team shares the jobs and takes turns. We wear gloves, never touch sharp or hazardous waste, and wash our hands afterwards. We sort waste into bins and water the plants.
Idea 3: Reflect
When we finish we reflect. What went well? What could be better? What will we keep doing every week? Small habits keep the school clean for everyone.
3. Worked examples
Example 1 (I show you): Plan the jobs
A messy yard.
- Sweepers.
- Sorters.
- Waterers.
Answer: Share jobs among the class.
Example 2 (We do it together): Stay safe
Sharp waste found.
- Do not touch.
- Tell an adult.
- The adult removes it.
Answer: Tell an adult about sharp things.
Example 3 (You try): Reflect
After the clean-up.
Show the steps and answer
- What went well?
- What was hard?
- What next?
Answer: We plan to clean every Friday.
Did you know?
Many schools around the world run weekly clean-ups, and some turn waste into compost for their gardens.
Why this matters
When everyone helps, our school is healthier and happier.
4. Explore: Class clean-up project
Plan and do a small clean-up.
- Make a plan with jobs.
- Put on gloves.
- Sweep and sort waste.
- Reflect together.
Think about it: what did you notice?
What did you notice? A team can do a lot in a short time.

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: “The caretaker does all the cleaning.” Everyone helps.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Plan a clean-up with three jobs and one safety rule.
- 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 plans and takes part in a school clean-up and reflects on the year. You do not need to be an expert to help.
- Do a family clean-up.
- Ask, “What did you learn this year?”
- Praise teamwork.
- 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: plan a school clean-up; share jobs fairly; work safely as a team; reflect on what we learned this year.
Prerequisite knowledge. None. Learners should be able to look, listen and talk about what they notice.
Materials. Brooms, bins, gloves, bags, chart paper and crayons. 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. Choose a checked area. Gather tools. Remove sharp items yourself. Prepare a plan sheet.
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). Ask, “How can we make our school cleaner?”
Explanation (10 min). Plan together.
Guided activity (10 min). Learners do the clean-up with adults.
Independent activity (10 min). Learners reflect.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. Who does which job? How do we stay safe?
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.
Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.
Misconceptions. “The caretaker does all the cleaning.” Everyone helps.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 12-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. Plan a clean-up with three jobs and one safety rule. Enrichment. Look for one new example near your home or school, draw 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.
