The best lesson that my parents taught me with money management was lunch money. I was given a set amount at the beginning of the week and had to budget it. I was given more than plenty of money to cover lunch. Anything extra I could use for snacks or save up.
Also, when it came time for me to drive, I had to pay for my own car and insurance. My parents werent in a position to help me a ton, they did what they could. However, this taught me the value of having things and taking care of them.
