How long would it take to count to a million? How long would it take to drive to the moon (if you could!)? How far could you walk in one year? How many children are needed to have a mass the same as an elephant? How many leaves are on the trees in Central Park?

Enrico Fermi is the father of "solving math problems we will never know the exact answer to." They are great for getting students to think mathematically and use problem-solving skills.

Fermi questions often require students to make reasonable assumptions and estimates about the situation in order to come up with an approximate answer. Students will learn to be able to explain and justify what they did when coming up with their solutions. Students’ answers may differ from each other, but if students have made sensible estimates and assumptions then the different answers should be “close” to each other.

Together, students will use questioning, discussion, measuring, estimating, model building and whatever else it takes to find the answers to problems that seem much bigger than they really are. Students will learn how to strategically break down these problems into manageable pieces and come up with sensible, feasible answers.
