Abstract
Matrix-based transformations are a central topic in mathematics and a foundational concept in computer graphics, yet students often struggle to connect formal algebraic operations with spatial effects. This paper presents a structured 60–70 minute collaborative classroom assignment that introduces translation, rotation, and scaling transformations through a contextualized computer graphics scenario inspired by the rendering pipeline. Students work in small groups where one learner operates in a virtual reality environment while peers observe, guide decisions, and document transformation sequences. By constructing geometric primitives and applying transformation matrices, learners directly experience spatial effects and the non-commutativity of matrix multiplication. The assignment bridges mathematics and computer science education in secondary school and serves as an entry point to undergraduate computer graphics concepts. We describe learning objectives, classroom orchestration, assessment strategies, and practical implementation guidelines. All materials are provided as an open educational resource to support reuse and adaptation.
