1. Math in the News The Butterfly Migration Each year the great Monarch butterfly migration from Canada to Mexico starts in September. This 2000-mile trek has become an international sensation. Scientists track the movements of the butterflies. And we can use their data to measure distance and speed. In this issue of Math in the News we study the migration of the Monarch butterfly.

2. Math in the News Watch this amazing PBS video to learn more about the Monarch butterfly’s migration from Canada to Mexico. http://video.pbs.org/vid eo/1063682334/

4. Math in the News You can estimate the straight-line distance the butterflies have traveled by connecting a line from two different migration-location sites. You would also make a note of the time period this represents.

5. Math in the News To calculate the average speed of the migration divide the total distance (in miles) by the total time (in hours)

6. Math in the News We will be tracking the migration of the butterflies from September to November. So keep coming back as we gather more data!
