Principle 5: Make It Yours - Adding Personality to Your Math IA

Don't just say "I like basketball"

 The IB’s personal engagement criterion isn’t just about proving you care – it’s your chance to turn a generic math exercise into a unique intellectual journey. While many students tack on a brief “I like basketball” intro, top-scoring IAs weave personal passion into every calculation, graph, and conclusion. Here’s how to do it right.

Personal Passion + Math Concept + Global Relevance

Connect your interests to a math concept and a broader issue to create a compelling IA. Here are two examples: 
  • Music IA: “My violin string tension analysis (personal passion) → Wave equation modeling (math concept) → Preserving traditional instrument craftsmanship (global relevance).” 
  • Sports IA: “My basketball trajectory calculations (personal passion) → Projectile motion with air resistance (math concept) → Optimizing accessibility for wheelchair athletes (global relevance).” 
The IB’s personal engagement criterion isn’t just about showing you care—it’s about making your project uniquely yours. While many students add a generic “I like basketball” intro, top-scoring IAs integrate passion into every calculation, graph, and conclusion.

Tips for Deeper Personal Passion

  • Weak Example: “I chose basketball stats because I play the sport.” This lacks depth and fails to show genuine engagement. 
  • Strong Example: “After missing 12 free throws in last season’s championship game, I became obsessed with quantifying shot consistency. My dataset includes 500 shots from my practice logs, annotated with fatigue levels and court positions.” This shows a personal connection, specific motivation, and a clear link to your analysis.

The “Double Reflection” Technique

  1. First Reflection: Explain how your interest shaped your IA’s direction.  Example: “My love for violin led me to explore string tension because I wanted to understand why my notes sounded off during performances.” 
  2. Second Reflection: Discuss how the math changed your understanding of your hobby. Example: “Using the wave equation, I realized string tension affects pitch more than I thought, inspiring me to adjust my tuning habits.”

The “Raw Data Authenticity” Technique

Showcase your journey by including handwritten raw data in your IA.

Example: append a scanned page from your lab notebook with entries like, “Feb 3: Rain disrupted outdoor measurements—switched to Monte Carlo simulation.” This adds a personal touch, demonstrating your problem-solving process and making your work feel genuine.

The “Real-World Connection” Technique

Engage with the broader community by emailing a relevant organization to share your results or seek their opinion.

Example: if your IA analyzes water bottle designs and plastic usage, email an environmental group to discuss your findings on sustainability. This shows initiative, connects your math to real-world impact, and can even provide feedback to enrich your reflection. Don't forget to include the email communication in the appendix!

Personal engagement turns your IA into a story that resonates with examiners. By starting with your obsessions and using advanced tactics like double reflection and annotated data, you’ll not only meet the IB’s criteria but also create a project that’s uniquely yours—one that stands out and scores high.
