About the Course

Excursions in Pre-algebra

Explore how mathematics relates to food, art, and history in this interactive pre-algebra course. Through weekly meetings, 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. Additionally, students may schedule weekly one-on-one virtual meetings directly with the instructor to answer questions or concerns./p>

Meeting times
In this course, students are required to attend scheduled online meetings. These online meetings may be used to conduct class sessions, office hours, group work, or other instructional needs. Your instructor will communicate with you to schedule the first virtual class meeting and inform you of subsequent meeting days/times. 

The class will meet 1 day each week, for 1 hour. 

In the event you have a scheduling conflict, and cannot attend the synchronous meeting, contact your instructor prior to the meeting. 

Time Commitment: 2-4 hours per week (1-hour of class time, 1-3 hours of independent work).
