What to Expect in this Course

We will have online class meetings using Zoom during our class time. The goal of our weekly meetings is to use our time together to accomplish tasks that may be more difficult to complete on your own. Of primary importance is to build and strengthen our class community. Learning can be more enjoyable and efficient when we learn together! 

Our online class meetings generally include time for Q&A (question and answer) and small group and class discussions to learn and deepen your understanding of course content. Students will also deliver assignments like projects, presentations, and exams during these meetings. Thus, your attendance and participation is very important for your successful completion of the course(s).

Your typical daily responsibilities are:

  • Read and watch sections assigned and complete assignments (about 2 sections per day). 
  • Respond to journals with short essay responses (generally 1 to 2 pages)

Your weekly time commitment for Math 140 is around 10 hours, which includes our class meetings.



Day 1: There will be a mandatory zoom meeting during the regular class time to welcome you to class and to give you a short introduction about the course and what to expect during the rest of the semester.

Typically on the first day of a face-to-face class, your instructor will say each name on the official roster and mark whether the person is present. A student that is not present on the first day is dropped from the class as a No Show and a waitlisted student is added in their place.

To confirm you are present and wish to continue with the class, you must attend the Day 1 zoom meeting and complete Journal 1 (will be available after the first zoom meeting) posted in Canvas. Please check the Module tab in Canvas once you login to the course in Canvas. If you do not submit Journal 1 within 48 hours of the first class meeting, you will be dropped from the course as a No Show. A waitlisted student will then be added in your place.
