Autumn Armstrong
Geometry teacher | Experienced educator in USA
I'm passionate about Geometry and hold a degree from Roanoke College. My journey in education has been shaped by a deep curiosity for shapes, patterns, and spatial relationships. With years of experience, I guide students through the intricacies of Geometry, making concepts clear and accessible. My goal is to instill a love for problem-solving and critical thinking in every student I teach. Let's explore the fascinating world of Geometry together!
