This project investigates how instructional pedagogy and physical classroom design can encourage students to justify their reasoning and develop conceptual understanding in mathematics. Traditional classroom structures, where students passively receive information while teachers deliver instruction from the front of the room, have remained largely unchanged since the early days of public education. This study asks how both spatial design and teaching strategies can be reimagined to better support students’ sense-making and reasoning.To explore this question, I conducted a comprehensive review of existing literature on mathematics pedagogy, classroom discourse, and learning environments. Drawing from this research, I am constructing a diorama that synthesizes research-based practices into a visual and spatial model.The primary outcome of this project is a three-dimensional model of an ideal mathematics classroom that supports justification, collaboration, and conceptual understanding. This model illustrates how thoughtfully designed tasks, strategic teacher moves, and an intentional classroom culture can work together within a supportive physical space to help students move from memorization and empirical reasoning toward deeper mathematical meaning.
