UnLock Math Curriculum
Geometry uses mathematics to study physical and abstract objects in space. Spatial awareness is closely related to geometry and is essential for solving abstract problems in upper-level courses such as Linear Algebra and Calculus.
Curriculum
Geometry
This course requires students to think critically and use logic to prove mathematical theorems and principles. Topics covered in this course include logic and reasoning, distance and length, angles, polygons, circles, perimeter, area, the coordinate plane, transformations, trigonometry, volume, surface area, and probability. This course is best taken in between Algebra I and Algebra II. While not a direct successor to Algebra I, Geometry requires that students have a strong foundation of algebraic skills in order to manipulate equations and solve problems that arise in Geometry. By completing Geometry, students become better prepared for Algebra II, improving their problem-solving skills, abstract and critical thinking, spatial awareness, and logical reasoning.
