In some parts of the U. S., snowy weather sometimes forces schools to close for a snow day. Now, some school districts have "e-days" instead. On an e-day, students still stay home from school, but they attend classes and do schoolwork online. Some people like this plan because school days don't have to be made up later in the year. But completing schoolwork online can be a problem for some students. What do you think? Should snow days be days off for students and teachers, or should students be required to attend e-classes?
