The national education union says that:
'Worksheets and textbook pages for maths and English can work if they are already used in school and all children have them at home. However, teachers cannot be expected to mark work. Schools should not be setting SATs tests or mocks at this time.'
Why shouldn't teachers be expected to mark work? Fair enough they shouldn't be marking as much as they do normally, but (say) 1-2 maths and english tasks per week to be marked is surely reasonable?
