Switch out president faces for those of mom, dad (or doggy!) and create your very own family currency at Festisite.
You can then use your imagination-made money for pretend play, or even use it as part of a creative reward system (kiddos can earn dollars for chores like walking the puppy, doing the dishes, etc., & cash them in for fun prizes like zoo visits, movie nights, sleepovers, and so on...) Teachers can use the same concept as a kooky classroom reward system, too.
International friends can also get in on the action (besides US dollars, there's rubles, rupees, dinars, kroners, etc.)
Fun stuff! Free stuff, too!
