Words to know
habits that keep us clean and healthy
to wash the whole body with water and soap
a small brush for cleaning teeth
tiny things that can make us ill
1. Discover: Ready for school
Kayode wakes up, bathes and puts on clean clothes. He brushes his teeth with a small amount of toothpaste. His mother checks that his nails are short and clean. “A clean body is a healthy body,” she says.
Think: Which hygiene habits did Kayode follow?
2. Understand: Keeping clean
Idea 1: Washing the body
We bathe every day with clean water and soap. We wash our face, ears, arms, legs and feet. We dry ourselves with a clean towel.
Idea 2: Teeth, nails and clothes
We brush our teeth with a toothbrush in the morning and before bed. We keep our nails short and clean. We wear clean clothes and wash dirty ones.
Idea 3: Why hygiene matters
Dirt and germs stay on skin, hair and clothes. If we do not keep clean, we can get skin problems, bad smells and tummy sickness. Good hygiene helps us stay well.
3. Worked examples
Example 1 (I show you): Morning routine
Get ready for school.
- Bathe with soap.
- Brush teeth.
- Put on clean clothes.
Answer: Bathing, brushing and clean clothes are good hygiene.
Example 2 (We do it together): Why short nails?
Dirt hides under long nails.
- Germs hide there.
- We eat with our hands.
- Short, clean nails keep germs away.
Answer: Short nails are easier to keep clean.
Example 3 (You try): Share or not?
A friend wants your toothbrush.
Show the steps and answer
- Toothbrushes carry germs.
- Do not share.
- Say, “I have my own.”
Answer: We never share toothbrushes or towels.
Did you know?
A toothbrush should be changed about every three months, or sooner if the bristles bend.
Why this matters
Clean habits keep our bodies healthy and help us feel good about ourselves.
4. Explore: Hygiene chart
Make a daily hygiene chart.
- List morning and night habits.
- Draw a tick box for each day.
- Tick each habit you do.
- Check your chart after a week.
Think about it: what did you notice?
What did you notice? Habits are easier when you do them every day.

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: “We only need to bathe when we smell.” We bathe every day.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Name five habits. Tick the ones you do every day.
- 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 daily hygiene habits that keep the body healthy. You do not need to be an expert to help.
- Do the routine with your child.
- Ask, “Why do we brush our teeth?”
- Praise good hygiene.
- 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: name hygiene habits; say why we keep clean; brush teeth in a simple routine; explain how hygiene prevents illness.
Prerequisite knowledge. None. Learners should be able to look, listen and talk about what they notice.
Materials. Paper, pencils, crayons and a pretend toothbrush for demonstration. 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. Draw a hygiene chart on the board. Prepare picture cards of clean and unclean habits.
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 do you get ready for school?”
Explanation (10 min). Teach hygiene habits.
Guided activity (10 min). Learners sort clean and unclean habits.
Independent activity (10 min). Learners make a hygiene chart.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. Is it a clean habit? Why?
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. “We only need to bathe when we smell.” We bathe every day.
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. Name five habits. Tick the ones you do every day. 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.
