The way our school is doing it, and how many in the state are, will be basing this semester's grade on just the 3rd quarter. That's great for students who did well for the 3rd quarter, not great for those who didn't. However, we decided for students who work really hard during this online learning, we can bump their grades up. We won't be reducing grades for students who slack off this quarter.
This basically follows guidance from the state that this is more an enrichment time rather than typical expectations. We are still teaching our students as close to normal as possible, but it is technically not required that they do the work. The longer they go without finding out it's optional, the better.
