Student lesson
- Reptiles have dry, scaly skin.
- They breathe with lungs.
- They are cold-blooded.
- Most lay eggs on land.
Words to know
a vertebrate with dry scaly skin
body temperature changes with surroundings
a tough plate on the skin
to lie in the warmth of the Sun
1. Discover: The lizard on the wall
Every morning a lizard climbs onto a sunny wall near school and lies still. “Why does it do that?” asks Ebo. His teacher says, “It is warming its body. Reptiles use the Sun for warmth.”
Think: Why might it move into shade later?
2. Understand: Reptiles
Idea 1: Reptile features
Reptiles are vertebrates with dry scales. They breathe air with lungs and most lay leathery eggs on land.
Idea 2: Cold-blooded
Reptiles are cold-blooded: their body temperature follows their surroundings. They bask in sunlight to warm up and rest in shade to cool down.
Idea 3: Kinds of reptiles
Snakes, lizards, crocodiles and tortoises are all reptiles. Each has special adaptations, like a tortoise’s shell.
3. Worked examples
Example 1 (I show you): Skin
Dry scales.
- Scaly.
- Dry.
- Reptile.
Answer: Reptiles have dry scales.
Example 2 (We do it together): Warm
Basking.
- Sun warms.
- Needs heat.
- Cold-blooded.
Answer: Reptiles bask to warm.
Example 3 (You try): Group
Tortoise.
Show the steps and answer
- Shell.
- Scales.
- Reptile.
Answer: A tortoise is a reptile.
Did you know?
Some tortoises live for over 150 years.
Why this matters
Reptiles help control pests and are part of many food webs.
4. Explore: Reptile detective
Compare reptile pictures to find shared features.
- Look at four reptile pictures.
- Find shared features.
- Make a poster of shared features.
- Add one adaptation for each.
Think about it: what did you notice?
What did you notice? Different reptiles shared dry scales.

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: “Reptiles are slimy.” Their skin is dry.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Name reptile features and explain basking.
- 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 reptiles. You do not need to be an expert to help.
- Watch lizards from a distance.
- Ask, “Why in the Sun?”
- Never touch wild snakes.
- 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 reptile features; explain cold-blooded; name reptile groups; compare reptiles with amphibians.
Prerequisite knowledge. Grade 2 animal ideas: animals grow and change, young and adult animals, simple life cycles and animal needs.
Materials. Reptile pictures, paper, pencils. 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. Print reptile pictures.
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 a lizard and ask, “Why does it lie in the Sun?”
Explanation (10 min). Teach reptiles.
Guided activity (10 min). Learners make posters.
Independent activity (10 min). Learners compare.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. What features does it have? How does it keep warm?
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. “Reptiles are slimy.” Their skin is dry.
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. Name reptile features and explain basking. 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.
