Hi @lenz,
Yes, that is correct. ---> I think you're saying that, if I only take attendance for one day of the week, the other 4 (unmarked) days are automagically (⬅️ love that and will use it forever) ignored. Is that correct?
For only have 10 dates to be visible, that is not something you can do and it would need to be submitted as an Idea in the Community.
For having the attendance "grade" be extra credit, while a little more work my recommendation would to:
- set "Attendance" to have a value (for calculating purposes)
- set "Attendance" to not count toward the final grade
- create an assignment called something like "Attendance (Extra Credit)"
- with a "Submission Type" of "No Submission"
- worth 0 points
- from within "SpeedGrader" for "Attendance (Extra Credit)" or from the "Grades" of the course, enter the points earned from the actual "Attendance" assignment (where attendance was logged) for each student
When combined together, steps 3 and 4, are similar to what is mentioned for the "Create New Assignment with Zero Point Value" option in How do I give extra credit in a course? - Instructure Community - 1253.
Technically, you could also use the "Create Extra Credit with Assignment Groups" (basically you would need to use weighted assignment groups and set the total value of the course so that it is above 100%) option from above link but that would depend on the layout of the rest of your course.
I hope this helps and makes sense.
