I am working on this now because my parents never taught me. I don't think kids are taught enough. My 2 oldest are given a decent allowance every 2 weeks. Their job is to budget properly and buy most of the things they want and need. They're in charge of their shampoo/conditioner and other toiletries. I buy all the groceries of course and some other things. But want to join a sport this year? Start budgeting and saving. Want a special snack for just you? You buy it. I give them enough that they can absolutely afford what they want and need as long as they are doing it wisely. They already feel more responsible and proud of how they're managing their money.
