The notion that price and value are not the same is not new but is often forgotten or neglected; the same goes for the consideration that things no longer needed may be useful for somebody else. This unit is designed to make youngsters think and re-think – on the example of the content of their schoolbags – which items are needed for what is, so to speak, their working lives and which are not. While rummaging in their schoolbags, they will also come across items of purely sentimental value. They are asked to explain why they wouldn't part with these, but will also be encouraged to consider alternative ways of disposing of things useless for them, as e.g. not throwing them away but giving them away / swapping them, because one of their schoolmates may need / want them.
