Common Core Critical Areas

Instructional time should focus on

  • forming, analyzing, testing and applying geometric con-jectures;
  • applying geometric transformations to build understanding of congruence, similarity, and symmetry;
  • developing deductive and inductive reasoning skills through proof; and
  • extending the study of two- and three- dimensional analy-sis of plane and space figures using postulates, theorems, and corollaries.
