Unit: Real-World Numeracy Skills

Lesson 1 of 31 Lesson Title: Introduction to Health Numeracy

---

WALT (We Are Learning To)

Understand basic health-related numerical concepts, including calculating and interpreting Body Mass Index (BMI) and pulse rate, using visual aids and graphic organisers.

---

Success Criteria

• Identify and explain at least two health measures (BMI and pulse rate).
• Use graphic organisers to interpret data related to health measures.
• Explain the importance of health numeracy in real-life contexts.

Victorian Curriculum Connections

Mathematics: VCE Numeracy and Victorian Pathways Certificate (aligned standards)

• AC9M7N09: Use mathematical modelling to solve practical problems involving rational numbers and percentages, formulate problems, choose representations and efficient strategies, interpret and communicate solutions.
• AC9M9M05: Use mathematical modelling to solve practical problems involving rates relevant to health contexts, interpret solutions.
• AC9M9ST05: Plan and conduct statistical investigations involving collection and analysis of different kinds of data and report findings.

General Capabilities

• Numeracy: Apply mathematical skills in health contexts.
• Critical and Creative Thinking: Analyse health metrics and their implications.
• Personal and Social Capability: Understand personal health data.

---

Resources

• Graphic organisers (BMI chart template, pulse rate tables)
• Visual aids (icons, images for BMI factors and pulse rate measurement)
• Calculators or digital devices (optional)
• Whiteboard and markers

Lesson Structure

1. Introduction / Do Now (8 minutes)

• Activity: Quick mental maths warm-up with health-related questions, e.g., "If a person weighs 70 kg and is 1.75 m tall, how do you think you could use these numbers to understand their health?"
• Purpose: Activate prior knowledge and engage interest with relatable health data.
• Materials: Whiteboard for jotting responses, images depicting health measures.

2. Explicit Teaching (10 minutes)

• Explain what BMI is: Body Mass Index as a ratio (weight ÷ height²), why it’s used, and typical BMI categories.
• Explain pulse rate: What a pulse rate is, how it relates to health, and normal ranges depending on age and activity.
• Use visuals: Display BMI charts and pulse rate tables, use icons to visualise each component.
• Link to Victorian Curriculum: Reference interpreting and communicating solutions applied to real-world health problems using rational numbers and percentages.

3. Guided Practice (10 minutes)

• Activity: Students work in pairs using a graphic organiser to calculate BMI for different fictional people and interpret pulse rates from provided data.
• Support: Provide step-by-step prompts in the organiser, dyslexia-friendly icons and labelled diagrams.
• Teacher Role: Circulate and scaffold mathematical modelling and interpretation of data.

4. Independent Practice (10 minutes)

• Activity: Individually, students identify another health measure (e.g., blood pressure or daily water intake) from a list and briefly research its importance and how it might be measured numerically.
• Differentiation: Use simple bullet-point resources or visual icon summaries for support; encourage advanced learners to explore more complex health metrics.
• Dyslexia-friendly: Research guided by images and icons, clear structured notes.

5. Review and Reflection (5 minutes)

• Discussion: Students share one health measure they identified and explain why numeracy helps understand it.
• Teacher summarises: Emphasise the practical importance of health numeracy in daily life and future lessons.
• Success criteria check: Ask students to confirm if they can identify and explain at least two health measures.

---

Differentiation Strategies

• Use graphic organisers and dyslexia-friendly written and visual materials.
• Pair work to support diverse learners through peer discussion.
• Provide calculators or digital tools for computation support.
• Allow oral responses or sketches for students who prefer non-written outputs.

---

Extension Activity (Optional / Homework)

• Research additional health metrics (e.g., cholesterol levels, blood sugar) and explain how numeracy helps monitor these.
• Create a simple infographic using icons to describe what the health metric measures and why it matters.

---

Teacher Notes

• Maintain gradual release of responsibility: beginning with whole-class introduction, moving to paired work, and then independent tasks.
• Emphasise relevance by situating health numeracy within students’ own lives.
• Use supporting visuals extensively to improve engagement and accessibility.
• Ensure vocabulary is clear; avoid jargon or provide explicit explanations.

This lesson aligns closely with the Victorian Curriculum Mathematics standards focused on real-world numeracy, mathematical modelling, and data interpretation, using relevant health contexts to engage Year 11 students in practical, meaningful learning.
