Well, I was listening to the podcast Strongly Connected Components and heard an interview with the director for the movie Cents.  Here is the trailer.

At the heart of the movie is a classic pre-calculus problem.  Which is worth more;  a penny on day one, and double that amount every day for a month, or a million dollars?  I’m excited to see this movie.  It looks like something my students might enjoy as well.  You can request a screening in your hometown.  See the webpage for Cents for more info.

I haven’t taught pre-calculus in several years, but this doubling problem reminded me of the fun I used to have reading One Grain of Rice: A Mathematical Folktale to my students.  They loved a rare story time in the middle of math class.  I’m sure they would love Cents as well.

Note to self – find some short, fun, calculus readings to share with students.  Any suggestions?
