My DS's school have the following:
Request that parents ensure all property is labelled with the child's name.
A lost property box.
That seems to be it. DS loses about £40-£50 worth of stuff a year at school. Some of it must be stolen, because it is all labelled. Is this average? Do any of your schools have any brilliant ways of keeping tabs on kids' stuff, or are the two methods above the only way realistically that schools can cope with this?
