I have five children so got one each for my 8 girl, 10 and 11 year old boys. Works real well. Teaches them how to divide there money into three groups so when time for siblings birthday, mothers day, Christmas they don't have to feel there saving is going away but just use the "account" money box for sharing. Also the Savings box money can not be used and we put into the bank account when it gets a large amount which teaches them saving for the future. The spending box they then can focus on something they want as if they keep spending they will never have money to buy. We do 50% savings 25% spending 25% sharing. Also there is a record book I help they with to keep track no one is taking there money and they are not using there save money.
