This isn't exclusive to US.

I remember having a class called "household" taking about an hour a week for a year or two in my primary education, where we learned mostly about cooking. Yes, I'm not joking. A class about finance could take the same amount of time, since apparently there is time available in the school schedule, and be very worthwhile.

Ironically, in the US that class was called "Home Economics"

We had a semester-long required course in high school (usually taken as a freshman) called "Career and Family" which focused on a re-hash of sex ed. and information on the dangers of drug abuse. We also had a semester-long required course in economics which focused more on the stock market and macroeconomics.

Way back in 4th/5th grade we had an hour or so each day for a couple of weeks focused on things like balancing a checkbook, but it was probably a bit too early on to do much good beyond reinforcing the required math skills. Then again, cooking was something I learned a year or two earlier in a summer-school class, so maybe some things do stick at that age.
