Just send them to school or don’t. Anything else is just trying to be cute with no clear benefit. Social distancing kids is just getting ridiculous. Seems most adults don’t know how to do any of these safety measures so expecting kids to do it is wishful thinking. Not to mention them needing to social distance to such extremes makes even being in person pretty darn pointless. Take temperatures if you must, probably shouldn’t have all the kids go through a lunch line, and possibly some other measures...that’s about as far as it seems sensible to me. They still will be closely interact, still need recess, and are going to be kids. I’m not sure one can avoid the inevitable of schools having to shut down again sooner rather than later.
