@NYwdwfan, if the main use is Google Classroom and virtual learning, a Chromebook would be the cheapest way to go. Our district has 1:1 Chromebook to student ratio for grades 3 and up, and many of those teachers are using Google Classroom. They are looking into seeing if they can purchase Chromebooks for 2nd and below right now to help those students with distant learning. They are looking for touchscreen Chromebooks that also flip into a tablet. Not sure the price.
You can access most things on Chromebooks that a normal laptop can, but you can't use any Microsoft products. But my guess is the teachers would likely be using Google products if they are doing Google Classroom, but obviously I am not their teacher.
