sleep and quiet time
1. Discover: The handwashing song
Before lunch, the class sings a twenty-second song while washing hands with soap. “Why so long?” asks Kofi. “Soap and time remove germs,” says the teacher. “That keeps all of us healthy.”
Think: Why do we wash before eating?
2. Understand: Habits
Idea 1: Hygiene
Hygiene means keeping clean. Wash hands with soap and clean water before eating and after the toilet to remove germs. Brush teeth twice a day.
Idea 2: Body care
Children need enough sleep, regular activity, safe drinking water and healthy food. Rest helps the brain learn.
Idea 3: Mind care
Feelings matter too. Talk to a trusted adult when worried. Play, laugh and spend time with friends.
3. Worked examples

If a learner struggles
- Find the misconception: “Water alone cleans hands.” Soap is better.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Explain healthy habits.
- 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 healthy habits. You do not need to be an expert to help.
- Wash hands together.
- Ask, “Why twenty seconds?”
- Talk about feelings.
- 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: list healthy habits; explain why hand washing matters; describe good sleep and activity; show care for feelings.
Prerequisite knowledge. Grade 2 body ideas: the five senses, parts of the body, healthy food, exercise and washing hands.
Materials. Paper, pencils, soap, water. 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. Set up handwashing 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). Show glitter hands and ask, “How did it spread?”
Explanation (10 min). Teach habits.
Guided activity (10 min). Learners test.
Independent activity (10 min). Learners make posters.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. Which habit keeps us healthy? 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. “Water alone cleans hands.” Soap is better.
