Course Description


Explore how mathematics relates to food, art, and history in this interactive pre-algebra course. Through collaborative activities and hands-on projects, you’ll sharpen your investigative skills, broaden your understanding of pre-algebra concepts, and connect mathematical knowledge to our world as you prepare for a more formal study of mathematics in middle school. This course is ideal for students who have a good understanding of the concepts leading up to pre-algebra, but want to expand their skills through world applications and projects. This course has synchronous virtual class meetings on Saturdays from 5-6 p.m. ET. Students may also schedule weekly one-on-one virtual meetings directly with the instructor to answer questions or concerns. Meetings will be recorded for students who are unable to attend due to scheduling conflicts.

Students will interact in CTY online classrooms and meetings that include peers, instructors, and occasional special guests.  Courses may include videos from the web. Recommendations or links at the end of videos are provided by the video host and are not CTY recommendations.  Students may have the option to post their work on public third-party sites (e.g., YouTube).  Virtual class meetings may be recorded for students to review. After a student completes this course, their projects may be used to illustrate work for future students.
