GeoGebra enables students to dynamically explore geometric figures, preserving dependency relationships to reveal invariants and deepen understanding. In our active learning classroom, students engage with GeoGebra to investigate Euclidean, spherical, hyperbolic, and taxicab geometries. I’ll share how GeoGebra facilitates mathematical discovery, transitioning from visual exploration to formal proofs. Additionally, I’ll discuss the interplay between GeoGebra and physical manipulatives, emphasizing when and why each is most effective in fostering geometric intuition. Attendees will receive access to a comprehensive set of GeoGebra activities and classroom worksheets.
