Words to know
things thrown away
rubbish left in the wrong place
rotted plant material that feeds soil
harm to air, water or land caused by waste
1. Discover: The litter trail
On the beach, the class finds litter: bottles, wrappers and bags. A crab hides in a plastic cup. “Litter harms animals,” says Ms Smith. Back in school, they make a sorting station with four boxes: paper, plastic, food scraps and other. They start a compost heap for fruit peels. “Less waste means a cleaner town,” says Abu.
Think: What waste did you throw away today?
2. Understand: Waste
Idea 1: Waste
Waste is things we throw away. Rubbish in the wrong place is litter. Too much waste causes pollution: it blocks drains, harms animals, dirties rivers and the sea and makes places unhealthy.
Idea 2: Three Rs
Reduce by using less and buying only what is needed. Reuse bottles, bags and boxes. Recycle paper, metal, glass and some plastics. Food scraps and leaves can be made into compost that feeds soil.
Idea 3: Safe action
Use a sorting station with adult help. Never touch broken glass, needles, medical waste or unknown rubbish. Wear gloves, wash hands and tell an adult about anything dangerous.
3. Worked examples
Example 1 (I show you): Sort
Banana peel?
- Think.
- Sort.
- Say.
Answer: Compost.
Example 2 (We do it together): Reuse
Old jar.
- Think.
- Plan.
- Say.
Answer: Pencil holder.
Example 3 (You try): Plan
A class action.
Show the steps and answer
- Think.
- Choose.
- Plan.
Answer: A sorting station.
Did you know?
Plastic bags can take hundreds of years to break down, while a banana peel can rot in a few weeks.
Why this matters
Less waste means cleaner places and healthier lives.
4. Explore: Sorting station
Set up a sorting station with clean, safe items (empty clean paper, plastic tubs). Sort pictures or clean items. Plan a class waste-reduction pledge.
- Set up.
- Sort.
- Discuss.
- Pledge.
Think about it: what did you notice?
What did you notice? Most waste could be reused.

Mastery and remediation
| Objective | Bronze (Developing) | Silver (Proficient) | Gold (Advanced) |
|---|---|---|---|
| O1 Say what waste is | 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 Use the three Rs | 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 Sort waste safely | 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 a class 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: “Litter does not matter.” It harms places and animals.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a sorting game.
- 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 reduce waste. Please reuse items at home and keep children away from dangerous rubbish. You do not need to be an expert to help.
- Reuse jars.
- Compost scraps.
- Stay safe around rubbish.
- 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 what waste is; use the three Rs; sort waste safely; plan a class action.
Prerequisite knowledge. Grade 2 ideas: children worldwide, shared resources, caring for the environment and rights.
Materials. Clean items, boxes, gloves. 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 a sorting station.
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 litter trail story.
Explanation (10 min). Teach waste.
Guided activity (10 min). Sorting station.
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 can we reduce waste?
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. “Litter does not matter.” It harms places and animals.
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 sorting game. 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.
