My children all came to a stunning revelation when I taught them minimum wage is about eight bucks an hour. That seems like a lot of cash to a kid, until they begin to do the math. Breakfast at McDonalds? You’ll need to work about 30 minutes for that. Want your nails done? That’s four hours, please. Add another hour if you want special gel. A new X-Box game? That’s 8 or more full hours of laundry, dishes, sweeping, mopping, and yard work. Suddenly, I saw their little minds grinding away at numbers before they asked for something new. It’s a great exercise in math and common sense.
