Rubric Breakdown

The IA is assessed based on five criteria, totalling 20 marks:

Criterion A: Presentation (4 marks)

1. This criterion tests your mathematical communication and presentation quality.
2. It evaluates your organization, clarity, and mathematical language usage.

Criterion B: Mathematical Communication (4 marks)

1. This evaluates your mathematical explanation and reasoning clarity.
2. It tests your mathematical notation, explanations, and logical development.

Criterion C: Personal Engagement (3 marks)

1. This criterion assesses your personal connection and mathematical thinking.
2. It evaluates your genuine interest, creativity, and independent thinking.

Criterion D: Use of Mathematics (6 marks)

1. This is a major criterion - testing your mathematical content and techniques.
2. It assesses mathematical relevance, complexity, and understanding.

Criterion E: Reflection (3 marks)

1. This evaluates your mathematical reflection and critical thinking.
2. It tests your evaluation of methods, results, and mathematical significance.

How to Interpret Your Grade from the Tool

1. The embedded grader calculates your total score out of 20 marks across all five criteria.
2. Here's how to interpret your results:
   1. 18-20 marks (Grade 7 territory): Excellent work with sophisticated mathematical applications. Minor refinements needed.
   2. 15-17 marks (Grade 6 range): Strong investigation with good mathematical modeling. Focus on application depth and interpretation.
   3. 12-14 marks (Grade 5 level): Competent work meeting basic requirements. Strengthen mathematical applications and real-world connections.
   4. 9-11 marks (Grade 4 range): Adequate foundation but needs significant improvement. Review mathematical content and practical applications.
   5. Below 9 marks (Grade 3 or lower): Major revision required across most criteria. Restructure approach and strengthen mathematical fundamentals.
