How it’s done
Money is abstract, and that's why it's hard to teach. Making it visible and physical — in three clear jars — turns it into something a child understands with their hands.
Every time money comes in (a small allowance, a gift, what they earn from an errand), it gets split across three jars:
- Spend. For whatever they want, whenever they want, no permission and no judgment. This jar is real freedom; if you control it, they don't learn to decide.
- Save. For something bigger that today's money won't cover. Patience lives here: watching the level rise jar by jar teaches that waiting has a reward.
- Give. For someone or something they care about. Letting them decide who to help ties money to values right from the start.
The transparency is the key: seeing the money go up and down, touching it, counting it. And the essential thing is that they decide — even when they decide badly. Blowing the whole spend jar on something that bores them ten minutes later is a cheap, powerful lesson that no warning of yours delivers the same way.
What it builds — the why
Good financial literacy, the kind you learn by deciding and not by listening: that money is limited, that you have to choose, that waiting buys access to more. The three jars build three muscles from an early age — spending with judgment, saving with patience, giving with meaning — that most people learn late and the hard way. And giving them real decision-making power, even to get it wrong, builds genuine autonomy and responsibility. The anchor is physical: the weight of the coins, the level rising in the save jar, the concrete pleasure of buying with their own money or giving out of their own pocket.
How it changes with age
6–9 Childhood
10–12 Preteens
13–15 Early adolescence
Variations
Link it with giving away what they no longer use (`dar-lo-que-ya-no-usa`): the give jar and generosity with things are the same lesson by two roads. For the one already thinking about earning their own, connect it with the teen's first business (`primer-negocio-del-teen`). Digital version for older kids: an app or a sheet where they see the same three destinations for the money.
What to watch for in your child
The system only teaches if the money is genuinely theirs to decide: if you approve or veto every purchase from the spend jar, they learn to ask permission, not to handle money. Let them get it wrong on the small stuff now, so they don't get it wrong on the big stuff later. Avoid turning the give jar into an obligation or a guilt trip — forced generosity doesn't count. And every child has their own relationship with money: some born savers, others spendthrifts; go with your child's temperament without judging it.
