Geometry 8

Geometry 8: This is a rigorous, fast paced program. Student will complete the Common Core curriculum of Geometry. Students must be highly motivated and possess the work ethic necessary to handle a challenging and fast paced level of instruction. Students will take the Common Core Geometry Regents in June. Students who successfully complete this course will receive on high school credit. Topics include analyzing geometric shapes and relationships, informal and formal proof, transformational geometry and coordinate geometry. The final exam is a local departmental exam.


Please note that the timelines listed below are a guide. Teachers modify their pacing based on student needs in order to ensure concept mastery.
