Although the main reason is that some children are losing out significantly or are at too much risk through being at home. But another factor has to be that schools need to try out social distancing procedures- new layouts, one way systems, staggered start/break times, smaller class sizes, more outdoor lessons, encourage handwashing and following instructions- since it is pretty likely that even in September we won't be able to return to normality. By trying things out now it will help inform the planning of how schools should look in September. Most universities seem to be planning for many courses to be online until at least Christmas so they don't see us returning to normality any time soon, and I think schools will need to be organised very differently next year too
