My education on this topic at this age range was a little more free-form. We were given a weeklong project in the 6th grade, which I remember pretty clearly:
Fast forward 6 years (we were 12). You are about to be kicked out of
your parents' house with the clothes on your back, $1,000 cash in your
pocket, your high school diploma, and a "best of luck" from your
parents. That's it. Your mission is to not be homeless, starving and
still wearing only the clothes on your back in 3 months.
To do this, you will find an apartment, a job (you must meet the qualifications fresh out of high school with only your diploma; no college, no experience), and a means of transportation. Then,
you'll build a budget that includes your rent, estimated utilities,
gasoline (calculated based on today's prices, best-guess fuel mileage of the car, and 250% of the best-guess one-way distance between home and job), food (complete nutrition is not a must, but 2000cal/day is), toiletries, clothing, and anything else you want or
need to spend your paycheck or nest egg on. Remember that the laundromat isn't free, and neither is buying the washer/dryer yourself. Remember most apartments aren't furnished but do have kitchen appliances, and you can't say you found anything on the side of the road.
The end product of your work will be a narrative report of the first
month of your new life, a budget for the full 3 months, plus a "continuing" budget for a typical month thereafter to prove you're not just lasting out the 3 months, and all supporting
evidence for your numbers, from newspaper clippings to in-store
mailers (the Internet and e-commerce were just catching on at the time, Craigslist and eBay didn't exist yet, and not everyone had home Internet to begin with).
Extra Credit: Make your budget work with all applicable income and
Extra Extra Credit: Have more than your original $1000 in the bank at
the end of the 3 months, after the taxes in the Extra Credit.
This is a pretty serious project for a 12-year-old. Not only were we looking through the classified ads and deciphering all the common abbreviations, we were were taking trips to the grocery store with shopping lists, the local Wal-Mart or Target, the mall, even Goodwill. Some students had photos of their local gas station's prices, to which someone pointed out that their new apartment would be on the other side of town where gas was more expensive (smart kid).
Some students just couldn't make it work (usually the mistakes were to be expected of middle-class middle-schoolers, like finding a job babysitting and stretching that out full-time, only working one job, buying everything new from clothes to furniture, thinking you absolutely need convenience items you can do without, and/or trying to buy the same upscale car your dad takes to work), though most students were able to provide at least a plausible before-tax budget. A few made the extra credit work, which was a lot of extra credit, because not only were you filling out a 1040EZ for your estimated income taxes, you were also figuring FICA and Social Security taxes which even some adults don't know the rates for, and remember, no Internet. Given that the extra-extra credit required you to come out ahead after taxes (good luck), I can't remember that anyone got that far.
The meta-lesson that we all learned? Life without a college education is rough.
