In 2013, it cost the U.S. Mint about 1.8 cents to produce a penny. And yet, the face value of a penny is just one cent. So which one of these is a better measure of a penny’s worth…and how much is money worth, period?
In this lesson, students apply operations on rational and decimal numbers to calculate how much the U.S. Mint spends on different coins. They also talk about what might happen if we got rid of some of our coins, and discuss what the value of money actually is
if it isn’t tied to something physical.
