Actually some of the major hospitals in Canada disagree with you. And if they use normal school days ( 5 days a week) and your school bubble is primarily the 26 students in your class....that is much easier to trace ...versus having a part time school bubble and part time various babie sitter / daycare bubbles and your regular family bubble. Get the kids back to school and have one family bubble and one school bubble because so much easier to trace....if tracing even needed since young children seem far more resistant and far less infectious . High school however is different matter since multiple classroom groups and rebellious to distancing...( and infectious) so they may need online schooling longer.
