That would only work if all children went back to school - at the moment parents have the choice whether or not to send them. My feeling (as a retired teacher) is that it will be very much child minding for the next few weeks with less than half the children back. Until social distancing is either reduced or relaxed completely, there just won't be the room in schools for all the children - one "normal class" would need to be split into at least two, so where are you going to put them all?
I would favour all children repeating this school year, starting September, but that probably isn't possible. Failing that, especially in Primary schools, the children staying with their present teacher and just carrying on next year. That way time wouldn't be wasted getting to know children and learning what they can do. Plus I think a lot of children, especially the younger ones, are going to find it very difficult to adjust to school life again, so having a teacher they know, would make it easier.
" a lot of teachers have had a rest during lockdown" Not true. In fact a lot I know have worked harder. They have had to adapt to finding, planning and presenting lessons on line, marking work that has come in, writing reports, making sure that children who don't have access to computers have paper copies, delivering the work to children etc. My great nephew's teacher has also visited all the children in her class once a fortnight, to make sure they are alright (staying at a distance of course) Most schools have also worked a rota with teachers going into schools a couple of days a week to cover the classes of key workers. Plus of course home schooling their own children. In fact a lot of my ex colleagues have said they will be glad to get back to normal.
