Course Description

Description

This proof-based geometry course, covers concepts typically offered in a full-year honors geometry course. To supplement the lessons in the textbook, videos, online interactives, assessments and projects provide students an opportunity to develop mathematical reasoning, critical thinking skills, and problem solving techniques to investigate and explore geometry. Students are also introduced to a dynamic software tool, GeoGebra, through projects that they create.

This course has synchronous virtual class meetings and students may also schedule one-on-one virtual meetings directly with the instructor to answer questions or concerns. The instructor will schedule meeting dates/times at the start of the course. Meetings will be recorded for students who are unable to attend due to scheduling conflicts. Additionally, students are invited to participate and ask questions in an open Help Room guided by instructors.

In this course, participation in forums and synchronous online virtual sessions are required as part of the final grade. Discussion forums are located within the course where students will be required to respond to a given prompt and then comment on responses by other students. Online sessions, led by a CTY instructor, are held in a virtual classroom, which allows for video, voice, text, screen sharing, and whiteboard interaction.

Students can contact their instructors via email with questions or concerns at any time. Live one-on-one online review sessions can be scheduled as well, to prepare for the graded assessments, which include homework, chapter exams, and a cumulative midterm and final.

Terms and Conditions

Virtual classrooms, and student activities in the classroom, may be recorded and added to the course as an ongoing asset for all class students to review. Students may be invited to interact in CTY community spaces that include students and instructors and potentially specially invited guests that are not enrolled in their course. Student contributions (e.g., projects, forum posts, etc.) may remain in the course after the student completes the course. These artifacts may be preserved to showcase student work or to continue important conversations.

Topics include:

  • Deductive and inductive reasoning
  • Direct and indirect proof
  • Parallel lines and planes
  • Congruence and similarity
  • Polygons
  • Perimeter, area, and volume
  • Right triangles
  • Circles
  • Coordinate geometry
  • Transformations and symmetry
  • Constructions and Loci

Geometry Help Room

Each week, all active students are invited to an open Geometry Help Room, which is led by a rotating staff of instructors. Students are encouraged to come with questions or just to meet other online students. Topics reviewed vary each week. 

The Geometry Help Room meets each Wednesday from 7 – 8 p.m. ET.

Technical Requirements

This course requires a properly maintained computer with high-speed internet access and an up-to-date web browser (such as Chrome or Firefox). The student must be able to communicate with the instructor via email. Visit the Technical Requirements and Support page for more details.

Zoom online virtual classroom
This course uses an online virtual classroom for discussions with the instructor. The classroom works on standard computers with the Zoom desktop client and also tablets or handhelds that support the Zoom Mobile app. Students who are unable to attend live sessions will need a computer with the Zoom desktop client installed to watch recorded meetings. The Zoom desktop client and Zoom Mobile App are both available for free download.

This course uses Respondus LockDown Browser proctoring software for designated assessments. LockDown Browser is a client application that is installed to a local computer. Visit the Respondus website for system requirements.

While Chromebook can be used to progress through the course, all exams must be completed on a PC or Mac.
