Curriculum Framework

International Baccalaureate Primary Years Programme (PYP)
Transdisciplinary Theme: Sharing the Planet
Central Idea: Human actions affect the environment, and understanding these impacts helps us care for the earth.

Learning Objectives

From IB PYP Language Scope and Sequence:

• Reading (Comprehension & Response):
  Students will identify multiple reasons presented in a text explaining how humans impact the environment.
  (Aligned with IB literacy strand and PYP Transdisciplinary Theme)

• Oral Communication:
  Students will engage in respectful partner discussions, asking clarifying questions or expressing disagreement to enhance understanding.
  (Supports IB learner profiles: communicator, thinker)

• Vocabulary Development:
  Students will use a glossary to determine or clarify the meaning of subject-specific terms (e.g., "energy").
  (Encourages inquiry and language acquisition within concepts)

---

Standards Alignment

Though IB does not map directly to US Common Core, these objectives align with:

• CCSS.ELA-LITERACY.RI.2.8 — Identify reasons in a text to support points.
• CCSS.ELA-LITERACY.SL.2.3 — Participate in collaborative conversations, asking questions and expressing opinions.
• CCSS.ELA-LITERACY.L.2.4 — Use a glossary to understand word meanings.

---

Materials

• Text: What a Waste by Jess French (simplified excerpts provided for 2nd graders)
• Large chart paper or whiteboard and markers
• Student individual dry-erase boards or notebooks
• Glossaries (printable simplified glossary with the word meanings)
• “Thinking Hat” props (e.g., paper hats or headbands) for discussion roles
• Visual aids (pictures illustrating human impact on the environment)
• Timer or visual timer countdown for transitions

Lesson Breakdown

1. Invitation to Wonder (5 minutes)

• Begin with a thought-provoking question: “What happens to the things we throw away?”
• Show a vivid image of pollution or litter affecting animals.
• Ask students to share briefly (1-2 sentences) what they think about it.
• Connect to IB learner profile: “As caring communicators, we want to understand how people’s actions affect our world.”

---

2. Guided Reading and Reason Identification (15 minutes)

• Read the adapted excerpts from What a Waste aloud with students, emphasizing clarity and engagement.
• After each section, pause and ask: “What reason did the author give about how humans impact the environment?”
• Record student responses on chart paper in 3 columns: Human Action → Impact → Reason Given
• Use visual cues or icons next to each point for comprehension support (e.g., a factory icon for pollution).
• Model “thinking aloud” to connect textual evidence to reasons.

---

3. Glossary Exploration: Understanding Energy (5 minutes)

• Present the glossary page with the word “energy” highlighted.
• Guide students to the glossary and model how to use it to find word meanings.
• Explain “energy” simply, using examples in students’ daily lives (e.g., using energy to play or grow).
• Invite 2-3 students to use the glossary to find meanings of other words connected to the text (optional extension).

---

4. Partner Discussion with 'Thinking Hats' (15 minutes)

Objective: Practice respectful discussion, clarifying questions, and disagreement.

• Introduce “Thinking Hats” that students wear (can be simple paper hats) to take roles:
  • Green Hat: Ask a clarifying question
  • Blue Hat: State a reason from the text
  • Red Hat: Politely disagree or offer a different viewpoint
• Pair students and assign roles, swapping hats after one exchange.
• Prompt pairs to discuss: “How do humans impact the environment based on what we read? Can you help each other understand better?”
• Circulate, guide, and gently scaffold respectful listening and responses.

---

5. Closing & Reflection (5 minutes)

• Gather students in a circle.
• Ask volunteers to share one new thing they learned about human impact on the environment or something they asked during partner talk.
• Connect back to the IB attribute of being “reflective learners.”
• Provide a simple exit ticket: On a note card, write one reason why caring for the environment is important.

---

Assessment

• Formative:

  • Observation of student participation during reading and charting reasons.
  • Monitoring partner discussions for use of clarifying questions and respectful disagreements.
  • Exit ticket review for comprehension of human impact reasons.

• Summative:

  • Option for a follow-up drawing/writing task where students illustrate or describe one way humans affect the environment with at least one reason from the text.

---

Differentiation & Inclusion

• Provide sentence starters for students needing support during discussions (e.g., “I’m wondering...,” “I respectfully think that...”).
• Visual aids and glossary support cater to visual and language learners.
• Pairing heterogeneous abilities encourages peer learning.
• Use of props engages kinesthetic learners.

---

Reflection for Educators

• How did students demonstrate understanding of multiple reasons humans impact the environment?
• Did students effectively use the glossary to clarify new vocabulary?
• Were students able to ask clarifying questions and express disagreement respectfully?
• Consider integrating this lesson with a future science or social studies unit on sustainability for deeper inquiry.
