Geometry – CLOSED

This course is designed to analyze and apply geometric concepts and measurements. The critical area focuses on properties of geometric figures and applying them in real-world situations. Students will engage in methods of using proofs to explain their answers.

For some students, this will be a new way of doing mathematics. Developing thinking and reasoning abilities used for proof-based mathematics is significant because students will be expected to do this type of mathematical thinking in Algebra 2 and beyond.

All Excelsior math instructors will be utilizing the Middle School & High School Big Ideas Math curriculum written by Ron Larson, Ph.D. and Laurie Boswell, Ed.D.  This material will prepare students for upper level and college math classes. Students will have access to a digital platform that has many tools to facilitate learning. The material Excelsior Classes math classes will use is not common core aligned.

Parents and students can expect weekly homework assignments, weekly quizzes, chapter tests, a midterm and final exam. 

Before registering, math students new to Excelsior Classes math classes should take the Geometry Readiness Assessment. While this course is typically done in high school following Algebra I. The goal of this assessment is to ensure students are well prepared to succeed in geometry.  If you have any questions about the results of the readiness assessment, please contact the instructor. Please know our goal is to set up your student for math success.

This class meets twice per week. Each meeting is 60 minutes. Regular, live attendance is strongly advised. Recordings are available if a class is missed or there is a conflict with another course. Students should watch the recording as soon as possible.

Please see this video for more about Excelsior Classes math courses and why you should choose us for your math education.

NOTE: As in all Excelsior Classes courses, math class instruction is tied to the curated syllabus, and the teacher will teach to the syllabus and not to a particular skill set of a student. In other words, the teacher cannot sacrifice content and expectations overall for an individual student as we need to stay in alignment with educational goals, class participant expectations, and NCAA approval of our courses.

Susan Hefner “retired” from her career as a mechanical engineer upon the birth of her oldest daughter in 2001.  She worked as a Senior Project Engineer for Corning Optical Fibers in Wilmington, N.C. after receiving her M.S. in mechanical engineering from UNC, Charlotte in 1996.  Her graduate coursework and thesis focused on precision engineering and specifically calibration methods for nanometer measurement devices.  Susan worked for Duke Energy (formerly Duke Power Company) as a Design/Systems Engineer Mechanical/Nuclear Engineering at Oconee Nuclear Station between her undergraduate and graduate degrees.  She graduated with a B.S. in mechanical engineering from NCSU in 1993.  Through her work experience and graduate work, Susan has experience in precision machine design, nanometer technology, fluid dynamics, structural analysis, nuclear reaction physics, regulatory compliance, chemical process engineering, heat transfer, thermodynamics, statistical process control, electrical system design, project management, production support, and she even completed an independent study in biomedical engineering.  Susan has always loved science and math and how they expose and reinforce the beauty of God’s creation.
