Geometry is a course for students in 9th and 10th grade. Geometry is offered as a Regents-level course as well as an Honors-level course. The fundamental purpose of the course 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 towards formal mathematical arguments. The course continues the integration of algebra, geometry, transformational geometry, and trigonometry topics, and prescribes that students experience mathematics in a coherent, useful, and logical manner that makes use of their ability to make sense of problem situations. The graphing calculator is used throughout the course to integrate numerical, algebraic, graphical and analytical understanding. Students will be required to use the calculator for class work, homework and for the Geometry Regents exam in June. Successful completion of this course and a passing score on the Geometry Regents exam provide students with the second of three Regents mathematics course credits necessary to earn a New York State Regents Diploma with Advanced Designation.
