Phone Plan Comparison investigation task, aligning it with an IB MYP unit structure, including Key Concept, Related Concepts, Global Context, and a Statement of Inquiry.
Key Concept:

• Relationships: The task focuses on the relationship between the number of months and the total cost of each phone plan. Students explore how changing variables (months, fees) affect the outcomes (total cost).

Related Concepts:

• Equivalence: Students explore equivalence when they compare two different phone plans by setting their total costs equal to each other to find when they are the same.
• Simplification: The task requires students to simplify and rearrange linear equations to find answers.
• Modeling: The phone plans are modeled using linear equations, helping students understand how real-world situations can be represented mathematically.

Global Context:

• Globalization and Sustainability: The task can be framed within this context by discussing how financial literacy and comparing costs help individuals make informed, sustainable financial decisions in a global economy. Understanding costs and savings impacts economic choices on a personal and societal level.

Statement of Inquiry:

Effective decision-making is influenced by un: derstanding the relationships between variables and applying mathematical models to real-world financial situations.

This structure emphasizes how mathematical thinking is vital for understanding and managing personal finances, encouraging students to apply their knowledge to everyday contexts.
