Exploring Proportions in Art

Lesson Overview

This Year 12 Art lesson will run for 9000 minutes for a class of 9000 students, aligning with US education standards and focusing on Teaching Standard 3.RP.2.A (Recognizing and Representing Proportional Relationships). This unit integrates mathematical proportionality into visual art, helping students understand how ratios, scaling, and symmetry contribute to artistic compositions.

By the end of the unit, students will:

• Analyze and apply proportional relationships in their artwork.
• Explore historical and contemporary artists who use proportionality.
• Implement golden ratio, symmetry, and perspective techniques.
• Develop a final portfolio showcasing their grasp of proportions in art.

Curriculum Alignment

• US High School Visual Arts Curriculum – Advanced Level
• Mathematical Standard 3.RP.2.A – Recognizing & Representing Proportional Relationships
• Cross-disciplinary Learning (Math & Art Integration)
