Common Core Geometry

  • The fundamental purpose of the course in Geometry is to formalize and extend students’ geometric experiences from the middle grades.  Students explore more complex geometric situations and deepen their explanations of geometric relationships, moving toward formal mathematical arguments.  Important differences exist between this Geometry course and the historical approach taken in Geometry classes.  For example, transformations are emphasized early in this course.  Close attention should be paid to the introductory content for the Geometry conceptual category found in the high school CCSS.   The Mathematical Practice Standards apply throughout the course and, together with the content standards, prescribe that students experience mathematics as a coherent, useful, and logical subject that makes use of their ability to make sense of problem situations.
