What kind of time frame?
The oldest is six atm.
if there is time, i would have them create a fantasy portfolio. they can take a month and track stocks to see what is going up and what is going down. with 5k i'd think a fund would be a better investment than individual stock.
I like fantasy portfolio idea. I understand your fund idea, but was thinking that individual stocks, although riskier, would teach them more, but a fantsy portfolio is good idea.
