- Trees are mature perennial plants.
Words to know
fully grown
a plant that lives one year
a plant that lives for many years
to make new living things like itself
1. Discover: The old mango tree
Next to the school stands a tall mango tree. It is older than the school. Every year it flowers and gives fruit. Next to it grows a small bean plant that will die after one season. “Both are mature plants,” says the teacher. “But one lives much longer.”
Think: How are the two plants different?
2. Understand: Fully grown plants
Idea 1: Mature plants
A mature plant is fully grown. It has strong roots, a firm stem, many leaves and flowers. Mature plants can reproduce, making seeds that grow into new plants.
Idea 2: Short and long lives
An annual plant, like a bean, lives for one season. A perennial plant, like a mango tree, lives many years and flowers year after year.
Idea 3: Compare seedling and mature
A seedling is small with few leaves. A mature plant is bigger, has many leaves and can make flowers and seeds. A mature plant makes more food and shelter for animals.
3. Worked examples
Example 1 (I show you): Seedling or mature?
A tall tree with fruit.
- Big and strong.
- Has fruit.
- Mature.
Answer: The tree is a mature plant.
Example 2 (We do it together): Annual or perennial?
A bean and a mango tree.
- Bean: one season.
- Mango: many years.
- Types.
Answer: The bean is annual; the mango is perennial.
Example 3 (You try): Compare
Seedling and tree.
Show the steps and answer
- Small vs tall.
- Few leaves vs many.
- No fruit vs fruit.
Answer: A mature tree is taller and can make fruit.
Did you know?
Some trees, such as bristlecone pines, are more than four thousand years old.
Why this matters
Mature plants give us food, wood and shade and make the seeds for the next generation.
4. Explore: Seedling vs mature
Compare a seedling with a mature plant.
- Find a seedling and a mature plant.
- Measure each.
- Count leaves.
- Compare in a table.
Think about it: what did you notice?
What did you notice? The mature plant was bigger and had flowers.

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: “All plants live for many years.” Some live one year.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Compare a seedling and a mature plant.
- 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 mature plants and plants with short and long lives. You do not need to be an expert to help.
- Walk and find young and mature plants.
- Ask, “Which lives longer?”
- Draw a tree together.
- 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: describe a mature plant; compare a seedling and a mature plant; say what a mature plant does; name different kinds of mature plants.
Prerequisite knowledge. Grade 1 ideas: plant parts (root, stem, leaf, flower), what plants need and caring for plants.
Materials. Rulers, pencils, paper and a hand lens. 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. Choose a safe place with plants of different ages. Prepare comparison sheets.
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, “Which plants are fully grown?”
Explanation (10 min). Teach mature plants.
Guided activity (10 min). Learners compare plants.
Independent activity (10 min). Learners record in tables.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. Is it mature? How do you know?
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. “All plants live for many years.” Some live one year.
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. Compare a seedling and a mature plant. 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.
