Second grade students began an exploration of Economics by reading Money Madness, by David Adler. This expository text explores the concepts of bartering, the history of money, and how we use money today. The students created a timeline about the history of money that spanned from bartering in 6000 B.C. to digital money in modern times. In this unit of study, the students will explore the concept of supply and demand, how people must make choices because of limited resources, the benefits and costs of saving and spending, and how the US trades with other nations for goods and services.
