Accelerated Geometry
I. Course Description
This course is a challenging, rigorous, proof-based approach to Geometry. Students in Seminar Geometry
analyze geometric figures using deductive reasoning, make conjectures and formulate hypotheses, draw
conclusions and make connections with other mathematical concepts, and model situations geometrically as a
problem solving strategy. Algebraic and geometric skills are integrated throughout the curriculum.

V. Assignments & Grading
Assignment sheets will be distributed periodically throughout the school year. Homework will
be assigned on a daily basis. Grades will be based on homework, algebra reviews, projects,
group activities, quizzes and tests. All students will take midyear and final exams. The Radnor
Middle School grading system and scale will be used to determine letter grades.
