@lhs20 I'm just trying to get a total, I won't even require it to do division, but I can see no way to do that. No calculated columns at all. This is so basic. I meant Microsoft has done some serious work on Teams for the classroom with all the integrations -- it is like seeing an acrobatic tight-rope walker who is unable to walk up a flight of stairs.
@dbasener I prefer that Teams doesn't try to be a grading program. There are too many ways to determine a grade rather than a simple average. If Microsoft wants to get into the gradebook business then I hope they will embrace standards based grading. That is, assessments should be sorted by standard or learning target and then show students' performance of each standard.
