I love the idea, I would most definitely teach them to not go all in, as i what if they all get sick and die. I like the idea of the chickens, the rabbits, the exotic fish, etc those can be tough markets to get into but can possibly work. What if and this goes back to savings you used KeePass or a password safe and set them each up there own account, being you like using SteemIt as a family experience, don't have to let the post or anything but they can simply watch a small investment grow, interest here is so much better than anything a bank or credit union will ever offer. Kind of a Savings account in case the worst with the other methods fails, such as the rabbit got sick you need the funds for the vet etc, it is kind of pre-save in a way that it is also growing and available if needed. I wish my parents had been more like you teaching me about how to use money effectively to gain more, not just a simple savings account, which is long past empty and never made more than about $20 growing up as far as I can remember.
