Slightly related: Took the kid to meet-and-greet/supply pickup with the new teacher, which was all done as drive-through in the school parking lot.
1.5-hour time slot per grade, with each teacher camping out under a different awning next to the parking lot with grocery bags of books & supplies for each student. Drive up wearing masks, go to the right teacher, roll down the windows, say hi, pick up the supplies, stop by the PTA awning on the way out & go.
Online classes start tomorrow.
