Your Kid is Running a Country

We have launched an activity called 'Create-a-Society.'  In groups, the students have designed island countries.  The climate, natural resources and natural features on their islands were all determined randomly by a spinner.  Groups will receive marbles for things like good behaviour, great answers, work completion etc.  They will use those marbles to purchase items for their islands such as roads, towns, power generation facilities, harbours, tourist destinations ect.  The better the students perform as a group, the more marbles they receive and therefore the more features and money-makers they can purchase for their islands.  Over the course of the game, the islands become more and more modern and industrialized.
