Student lesson
- An animal life cycle has stages.
- Animals are born or hatch, grow, become adults and have young.
- The cycle repeats with the next generation.
- Different animals have different cycles.
Words to know
the stages of life from birth to adult and back to young
the start of an animal’s life
a fully grown animal that can have young
to have young
1. Discover: The goat family
On the school farm, Mr Ansah draws a circle on the board. “A kid is born. It grows. It becomes a nanny goat. She has a kid. And it begins again.” The class draws arrows between pictures.
Think: Where does the circle start?
2. Understand: Animal life cycles
Idea 1: Stages
An animal’s life cycle has stages: birth (or hatching), growing, becoming an adult and having young.
Idea 2: A cycle
When the adult has young, a new life cycle starts. The stages repeat, which is why we call it a cycle.
Idea 3: Different cycles
A goat’s young looks like a small goat. A butterfly goes through very different stages. Every animal has a life cycle, but they are not all the same.
3. Worked examples
Example 1 (I show you): Order
Adult, born, grow, young.
- Born first.
- Then grow.
- Then adult, then young.
Answer: Born, grow, adult, have young.
Example 2 (We do it together): Why a cycle?
New young start again.
- Adult has young.
- Young grow.
- It repeats.
Answer: It repeats.
Example 3 (You try): Different
Goat and butterfly.
Show the steps and answer
- Goat grows bigger.
- Butterfly changes shape.
- Both have cycles.
Answer: Both have life cycles but different ones.
Did you know?
The mayfly may live as an adult for only a day, yet it also has a life cycle.
Why this matters
Life cycles help us understand how animals live and how populations continue.
4. Explore: Life cycle wheel
Make a life cycle wheel for a goat or hen.
- Draw four stages.
- Cut and arrange in a circle.
- Add arrows.
- Explain to a partner.
Think about it: what did you notice?
What did you notice? The cycle returns to the start.
5. Practise

Mastery and remediation
| Objective | Bronze (Developing) | Silver (Proficient) | Gold (Advanced) |
|---|---|---|---|
| O1 Say what a life cycle 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 Name the stages | 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 Put stages in order | 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: “Animals stop at adult.” They have young.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Put four life stages in order and explain.
- 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 what an animal life cycle is. You do not need to be an expert to help.
- Talk about a pet’s life stages.
- Ask, “What comes next?”
- Draw a cycle.
- 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 a life cycle is; name the stages; put stages in order; draw a simple life cycle.
Prerequisite knowledge. Grade 1 ideas: animals around us, what animals need and how animals are alike and different.
Materials. Paper circles, pencils, crayons and safe scissors. 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. Cut paper circles. Prepare a model wheel.
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, “What happens after an animal grows up?”
Explanation (10 min). Teach life cycle.
Guided activity (10 min). Learners make wheels.
Independent activity (10 min). Learners present.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. What stage is next? Why does it repeat?
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. “Animals stop at adult.” They have young.
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. Put four life stages in order and explain. 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.
