It's all just a matter of time. The resource provides four Fermi questions in reference to time. The questions are open-ended and require classmates to make use of estimation and dimensional analysis.

A fermi number is a rough estimate of a quantity that is difficult or impossible to measure. Individuals design a process for making an estimation of a given scenario. For example, they determine a plan for estimating the number of...

It is about this big. An assessment provides three questions on the estimations of volume. Pupils determine the quantities needed and use dimensional analysis to arrive at estimations involving dollar bills, paint, and gasoline.

How many hot dogs does Fenway Park go through in a year? Learners estimate answers to this question and more as they work through the task. Problems require participants to make assumptions and use those assumptions to make estimations.

Enrico Fermi, the physicist responsible for the first nuclear detonation, was known for his ability to estimate with little or no data. Use this task to have your classes practice their Fermi skills. They estimate the magnitude of three...

Wait, there is an estimate for how much that weighs. The resource contains three questions about weight. Using dimensional analysis and benchmarks, pupils determine a reasonable weight for trash, food, and a grain of salt.

How long does it take to get to the end of a toilet paper roll? Pupils use their estimation strategies to find lengths of common items. For example, knowing the area of a roll of toilet paper, scholars determine the length of the full roll.

This tutorial from the Math Forum provides the approach to problem solving made famous by Enrico Fermi. Fermi, a brilliant Italian physicist, used estimation frequently in problem-solving.

Based off of the hit television show NUMB3RS, this lesson has students explore various methods of estimation. Framed in the context of a ballroom dance, students are to determine approximately how many people fit in the ballroom. A...
