Have you ever played the online game, 'My Free Zoo'? Our niece recently got us hooked on it. It is a free game that also has options to purchase 'diamonds' so that higher graphic animals can be put into the zoo. (Thus, I think we were invited to begin playing because she knew we used Paypal. haha) But it really is a Neat way for kids to learn how to balance money, have employees, take care of animals, etc. You begin with a very small space and then later on in the game have options to make it bigger. My sign in name is happyholly40 if anyone starts playing and wants a 'friend'. Friends let you trade cards. The site that created it has other free online games that are similar in nature but we have not tired these ones yet. Do any of you play a similar type of game?
