# Highest grossing movies

Let your students develop their own ideas about compounded percent change while they have the opportunity to speak about the upcoming Academy Awards show.

Worldwide box office income is compared for the top ten grossing movies of all time. Is total gross the most appropriate way to judge the popularity of a movie?  How does inflation and increasing ticket prices come into play? Inflation rates are used to let students calculate how the money of 1997 compares to the money of 2013. The idea of this comparison is to encourage students to develop their own understanding of exponential growth.

This activity is accessible to students as young as 5th or 6th grade once they have become familiar with computing with exponents and percents.  The activity is appropriate for middle schoolers and high schoolers as well by allowing students to generalize a formula for finding the adjusted-for-inflation earnings of any movie.

For members we have Word docs, an Excel sheet and solutions.

• Do the best movies make the most money? - Ten movies are nominated each year for the Academy Awards.  Students compare the votes that the last 20 nominated movies received with their worldwide gross in theaters.  Does number of votes for best picture correlate with money earned at theaters?
