Unit Context

This lesson (Lesson 11 of 30) forms part of the Year 12 unit "Navigating the Numeracy Landscape". The focus is to investigate a variety of financial products and understand their numeracy implications, aligned closely with the Australian Curriculum (v9) Mathematics for senior secondary students.

---

Learning Objectives

By the end of the lesson, students will be able to:

• Analyse and compare different financial products including savings accounts, loans, credit cards, and investment options, focusing on features such as interest rates, fees, and compounding effects.
• Apply numeracy skills to calculate outcomes associated with these financial products using appropriate mathematical methods and digital tools.
• Evaluate the implications of choosing specific financial products in real-life contexts.
• Communicate findings effectively using mathematical language and representations.

Australian Curriculum Links

• Mathematics > Year 12 > Number and Algebra
  • ACMMG293 (v9 code example for Year 12 equivalent) — Interpret and use the structure of financial products, including percentages, interest rates, and compounding.
  • ACMMG294 — Use financial mathematics to solve problems involving loans, compound interest, and investments.
• Mathematical proficiencies developed:
  • Understanding and Fluency
  • Problem-solving
  • Reasoning and Communicating

Note: Year 12 curriculum codes are typically extensions or applications of financial numeracy elements from senior secondary. The above codes have been extrapolated based on Years 9–10 and Years 11–12 continuums in the AC v9.

Lesson Breakdown

Time	Activity	Description	Resources
5 mins	Warm-up: Introduction and Context Setting	Introduction to financial products - ask students what financial products they know (e.g., savings accounts, loans, credit cards). Briefly discuss why understanding these products is important for managing money.	Whiteboard, markers
10 mins	Research and Exploration (Group Work)	Divide students into 4 groups. Each group explores one financial product (e.g., savings account, personal loan, credit card, investment fund). Provide fact sheets outlining key terms: interest rates (simple and compound), fees, minimum balances, repayment schedules. Groups discuss the numeracy involved, especially how costs or gains accumulate.	Fact sheets, calculators, laptops/tablets (for digital research)
10 mins	Calculations and Modelling	Each group performs calculations based on example scenarios:

• Calculate total interest earned on $5,000 in a savings account at a 2.5% annual compound interest over 3 years.
• Calculate the total repayment of a loan of $10,000 over 5 years at a given interest rate.
• Estimate interest charges on credit card debt for one month with minimum repayments.
• Model the growth of an investment with regular monthly contributions.
  Reinforce use of formulas, digital tools or spreadsheets where applicable. | Calculators, spreadsheets (Excel/Google Sheets), formula sheets | | 10 mins | Group Presentation and Discussion | Groups present their findings focusing on numeracy implications and consumer decision-making impact. Teacher facilitates discussion highlighting the importance of mathematics in evaluating financial decisions. | Presentation slides or posters from groups | | 7 mins | Individual Reflection Task | Students write a brief reflection: How can an understanding of numeracy in financial products influence your future financial decisions? Encourage referencing vocabulary and calculations from the lesson. | Student notebooks or digital document | | 3 mins | Summary and Homework Introduction | Summarise key points, clarify doubts. Introduce homework task to research a financial product independently and prepare a short report analysing its numeracy features and costs. | Homework instructions sheet |

Assessment

• Formative assessment: Observation of group discussions and calculations.
• Group presentations evaluated for understanding of numeracy concepts and clear communication.
• Individual reflection task to assess personal understanding and ability to connect numeracy to financial literacy.

---

Differentiation Strategies

• Provide scaffolded worksheets for students needing extra support with calculations.
• Challenge advanced students to compare multiple financial products or simulate scenarios with varying interest rates or terms.
• Use digital tools to aid understanding and calculations for diverse learning preferences.

---

Digital and Cross-curricular Connections

• Use of spreadsheets supports ICT capability.
• Discussions around financial products link to personal, social, and ethical capability.
• Incorporate First Nations perspectives by discussing traditional and modern financial practices where relevant.

---

Teacher Notes

• Emphasise real-world application to motivate learners.
• Reinforce mathematical terms: compound interest, principal, rate, term, fees.
• Encourage questioning of financial product terms and conditions.
• Provide calculators or apps capable of compound interest calculations for efficiency.

This lesson plan is designed to actively engage Year 12 students in the Mathematics curriculum, developing critical financial numeracy skills aligned with the Australian Curriculum v9 framework while fostering practical decision-making capabilities.
