Money plays a huge role in society in a variety of ways, such as in business, at people's jobs, and even in education. A currency in the most specific sense is money in any form when in use or circulation as a medium of exchange, especially circulating banknotes and coins. A currency is a system of money (monetary units) in common use, especially for people in a nation. In the theme- World Around Us, students of Grade 4 learned about different currencies wherein they noticed different varieties of visuals on banknotes of various countries. For example, there are images of people, plants, birds, animals, monuments, or events on banknotes.
