ACT
In this activity, students apply what they have learned about weighted averages, isotopes, and systems of equations to a new situation - coins in a sealed container. They learn some historical information regarding the composition of pennies and then are faced with a challenge: to determine the number of pre-1982 and post-1982 pennies that are contained in a sealed container without opening the container.
