Check Canvas.
You'll be able to see (on a Jamboard) which problems we went over, and what we wrote down about them. That said, what you won't see are the extra comments/insights/questions that I or other classmates add to the work written on the page. So it would be a good idea to also review those Jamboard notes with a trusted classmate to get a fuller picture and deeper understanding.
Whenever there is a P&P (Participation and Presentation) quiz in Canvas for a class day you miss, you should fill out the quiz.
The first question asks if you completed the tasks/problems for that day. If you did, then give yourself credit!
The second question asks if you worked with a group/team on a Jamboard during class time. You'll have to say no on this one.
The third question asks if you presented (at least a part) of your group's work during class. You'll also have to say no on this one.
If your absences are rare and/or occur because of some extenuating circumstances (like, maybe you have a prolonged illness), then by the end of the term, your average on the P&P portion of your grade will be good by the end of the semester.
If your absences are frequent and not excused, then your lack of participation in class will have a negative impact on your final grade. Discussion with your classmates and with me is an important part of the learning process.
If you find you need an extension on some assignment, you may submit the following Google Form. The form amounts to a "no questions asked" extension policy, but does come with some Terms and Conditions.
Well, here are some slides to accompany a super-over-simplified lecture I gave on my point of view.
But, if you want much more info, you should visit the Academy of Inquiry-Based Learning website.
