The authors describe an economics-based game they have developed to instruct student teachers in the value of games and gaming for developing reasoning and decision-making skills in economics in K-12 students (5-18-year-olds). The game is designed to progress through each grade level so that by high school students have a thorough appreciation and understanding of how the world economy is interconnected. Gaming is a feature that both authors are using as part of their curriculum within their social studies methods courses. In particular, the authors are encouraging the use of more sophisticated modes of instruction for elementary teachers in order to redeem the value of the social studies within the elementary curriculum.
