As most of the 13,000 districts in the U.S. plan for re-opening schools, a few photos of re-opened ones in other countries may give readers a sense of what’s in store for American parents preparing to send their sons and daughters to school.

Schools re-open in different parts of China.

In Denmark:

My guess is that re-opened U.S. schools will vary greatly in arranging classroom space (as these photos illustrate) but there will be constants of mask-wearing and attempts to physically distance students in classrooms– good luck on hallways and cafeterias–until vaccines are available.
