Migration Rate Math Activity
(Teaching Suggestions)

Each of the observers below saw migrating monarchs. Where was the migration the strongest? It's hard to tell at first when you read the comments. However, if you calculate the migration rate it's easy to compare the observations. Practice calculating the migration rate yourself, and put the sightings in order. When you're done, check our answers.
