Geometry provides a curriculum focused on the mastery of critical skills and the understanding of key geometric concepts. Through a "Discovery-Confirmation-Practice"-based exploration of these concepts, students are challenged to work toward a mastery of computational skills, to deepen their understanding of key ideas and solution strategies, and to extend their knowledge through a variety of problem-solving applications.
Course topics include reasoning, proof, and the creation of a sound mathematical argument; points, lines, and angles; triangles and right triangles; quadrilaterals and other polygons; circles; coordinate geometry; and three-dimensional solids. The course also includes a look at special topics in geometry, such as constructions, transformations, symmetry and non-Euclidean geometry. The course concludes with geometric models related to probability and statistics.
This course supports all students as they develop computational fluency, deepen conceptual understanding, and apply mathematical process standards. Students begin each lesson by discovering new concepts through guided instruction, and then confirm their understanding in an interactive, feedback-rich environment. Modeling activities equip students with tools for analyzing a variety of real-world scenarios and mathematical ideas. Journaling activities allow students to reason abstractly and quantitatively, construct arguments, critique reasoning, and communicate precisely.
