IB MYP Investigation Task:Construct _Substituting Algebraic Expressions

IB MYP task based on constructing and substituting algebraic expressions in the context of travel tickets. This task aligns with Criterion D (Applying mathematics in real-life contexts) strands

• Construct Algebraic Expressions
• Substitute Values
• Analyze and Interpret
• Reflection

Criterion D: Applying Mathematics in Real-life Contexts
Strand D1: Identify relevant elements of authentic real-life situations.

Understand the ticket types, base prices, and discount structures.
Strand D2: Select appropriate mathematical strategies.

Use algebra to create expressions that represent ticket pricing with discounts.
Strand D3: Apply the selected mathematical strategies correctly.

Substitute values into your expressions to calculate total costs accurately.
Strand D4: Discuss results considering the context.

Analyze which ticket combination offers the best value and reflect on discount effects.

Reflection on ATL Skill: Transfer
After completing the task, students can reflect on their use of transfer skills with questions such as:

• How did the mathematical concepts I learned in class help me solve a real-world problem involving ticket pricing?
• Can I think of other areas or subjects where understanding discounts and constructing algebraic expressions might be useful?
• How can I apply the strategies I used in this task to other situations outside of mathematics?
• By integrating transfer skills into this task, students are encouraged to recognize the wide applicability of their learning, fostering a deeper understanding and appreciation of the relevance of mathematics in everyday life.
