What a great question Mark. My school is starting its face to face instruction tomorrow (Sept. 3), but parents had a choice in Texas to either do virtual or face to face learning. Since our numbers were so high we put all kids on virtual learning for the first three weeks starting back in August. But, tomorrow is the day the face to face group comes back on campus. I am not going to lie, we are all a little nervous. We have lots of plans in place for social distancing and spacing kids out at our high school, but 70% of our population decided to choose face to face. Needless to say we will have a lot of kids at school tomorrow. The protocols make school feel more like a prison than a school. So wish us luck! 

In your case, I would recommend that you do asynchronous learning with the kids you are not seeing face to face that day. If they don't have Internet, the fact that you are going to see them some of the days will allow you to put a packet or a Book of Knowledge into their hands for working on their own at home. For those who have Internet there are some great resources out the there to help with asynchronous learning. I think kids want structure. So as much as you can provide it, that would be great. 

Good luck!  I am interested to see what others think.
