Student lesson
- Puberty is normal and healthy.
- Hormones cause the changes.
- Timing varies from person to person.
- Hygiene, sleep and talking help.
Words to know
the stage when the body changes toward adulthood
a chemical messenger in the body
a period of rapid growth
habits that keep the body clean
1. Discover: Growing at different times
In Class 6, Kojo has grown 10 cm taller this year while his friend Yaw has hardly grown. “Am I late?” Yaw asks. The teacher explains: “Everyone starts puberty at a different age, usually between 8 and 14. Both of you are fine.”
Think: Why is it important to know that timing varies?
2. Understand: Puberty
Idea 1: What it is
Puberty is when hormones trigger changes: a growth spurt, body hair, sweating more, skin changes, and changes in the body’s reproductive system. Girls begin to have periods; boys’ voices deepen.
Idea 2: Everyone different
Puberty usually begins between about 8 and 14 and takes several years. Early or late is normal. Bodies come in many shapes and sizes.
Idea 3: Looking after ourselves
Wash daily, wear clean clothes, use deodorant if needed, eat well, exercise and sleep about 9 to 12 hours. Feelings can change quickly, so talk to trusted adults, friends or a school counsellor.
3. Worked examples
Example 1 (I show you): List
Changes.
- Growth.
- Hair.
- Sweat.
Answer: Several changes.
Example 2 (We do it together): Explain
Timing.
- Different ages.
- Both normal.
- No comparing.
Answer: Everyone differs.
Example 3 (You try): Plan
Hygiene.
Show the steps and answer
- Wash.
- Clean clothes.
- Sleep.
Answer: Daily habits.
Did you know?
Teenagers need around 8 to 10 hours of sleep, partly because growth hormone is released during sleep.
Why this matters
Knowing what to expect helps young people feel confident and kind to each other.
4. Explore: Hygiene kit
Design a poster of a daily hygiene and wellbeing routine, including washing, sleep, food, exercise and talking about feelings.
- List habits.
- Plan the day.
- Draw the poster.
- Share kindly.
Think about it: what did you notice?
What did you notice? Small habits made a big difference.

|---|---|---|---|
| O1 Define puberty | 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 List common changes | 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 Explain different timing | 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: “Everyone changes at the same time.” Differs.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Explain puberty simply.
- 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 puberty respectfully, following school policy. You do not need to be an expert to help.
- Talk openly and calmly.
- Say changes are normal.
- Offer a trusted adult.
- 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 puberty; list common changes; explain different timing; describe hygiene and wellbeing habits.
Prerequisite knowledge. Grade 5 ideas: the main organs, the senses, healthy eating and keeping the body healthy.
Materials. Posters, markers. 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. Confirm school policy and family notice; prepare an anonymous question box.
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). Look at growth charts and ask, “Does everyone grow at the same time?”
Explanation (10 min). Teach puberty respectfully.
Guided activity (10 min). Learners make posters.
Independent activity (10 min). Learners ask anonymous questions.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. What changes? What helps?
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. “Everyone changes at the same time.” Differs.
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. Explain puberty simply. 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.
