When money moves between individuals or groups it is called a transaction. Join the Biz Kids and you'll follow a single dollar bill as it moves from a depositor's hand across the counter, down to the vault, over to the Federal Reserve, and finally out to a project the bank is financing. Visit the branch of a real credit union inside a high school where the students are the tellers. Watch the ebb and flow of money as the kids examine the concepts of supply and demand. Meet a young man who began collecting books to read to his grandmother and soon found himself as the head of a national book business.
