- We put waste in bins.
Words to know
things we throw away
rubbish left on the ground
to use again
to make into something new
1. Discover: The plastic bag
Fatmata finds a plastic bag in the stream. A fish nibbles it. “Oh no,” she says. “Litter can hurt animals.” She asks her teacher how to help. “We can use a cloth bag instead,” says Ms Smith. “We can reuse bags and put waste in the bin.”
Think: What waste do you make?
2. Understand: Waste
Idea 1: Waste and litter
Waste is what we throw away. It becomes litter when it is dropped in the wrong place, like a wrapper on the road or a bottle in a stream.
Idea 2: Harm
Litter makes places dirty and ugly. It can block drains and cause floods. Animals can swallow or get trapped in plastic. Rubbish in rivers reaches the sea.
Idea 3: 3 Rs
We can reduce (use less), reuse (use again) and recycle (make into something new). We use a cloth bag, refill a bottle, reuse a jar and sort paper, plastic and metal for collection.
3. Worked examples
Example 1 (I show you): Sort
Sort waste.
- Look.
- Group.
- Put in bins.
Answer: Paper, plastic, food waste.
Example 2 (We do it together): Reuse
Reuse a jar.
- Think.
- Clean.
- Use again.
Answer: Use it for pencils.
Example 3 (You try): Reduce
Use less.
Show the steps and answer
- Think.
- Say.
- Do.
Answer: Use a cloth bag.
Did you know?
A plastic bottle can take hundreds of years to break down, so it is very important not to litter.
Why this matters
Less waste means cleaner places and safer animals.
4. Explore: Waste sort
Sort clean sample waste (paper, plastic, metal, food peelings) into groups. Think of one way to reuse an item.
- Look.
- Sort.
- Reuse idea.
- Share.
Think about it: what did you notice?
What did you notice? Much waste could be reused.

Mastery and remediation
| Objective | Bronze (Developing) | Silver (Proficient) | Gold (Advanced) |
|---|---|---|---|
| O1 Define waste and litter | 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 harm | 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 Reduce reuse recycle | 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 disappears.” It stays.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Draw waste in a bin and litter on a road.
- 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 about waste and litter. Please reuse things at home together. You do not need to be an expert to help.
- Use cloth bags.
- Reuse jars.
- Show how to use bins.
- 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 waste and litter; explain harm; reduce reuse recycle; sort waste.
Prerequisite knowledge. Grade 1 ideas: natural and human-made features and sharing resources.
Materials. Clean paper, plastic, card. 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 clean sample waste.
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 plastic bag story.
Explanation (10 min). Teach waste.
Guided activity (10 min). Sort.
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. What is waste? What is litter? How can we reduce it?
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 disappears.” It stays.
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. Draw waste in a bin and litter on a road. 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.
