|GEORGE WASHINGTON'S NOSE
On her way to visit Horace Mann University, Casey stopped by Mount Rushmore in South Dakota. The park ranger gave a talk that described the history of the monument and provided some interesting facts. Casey could not believe that the carving of George Washington's face is 60 feet tall from his chin to the top of his head!
However, when a tourist asked about the length of Washington's nose, the ranger was stumped! Casey came to her rescue by measuring, calculating and getting an answer. How did Casey get an answer?
Your Task: Figure out the length of George Washington's nose on the monument. Work with your team to come up with a strategy. Show all measurements and calculations on your paper with clear labels so anyone could understand your work.
What is this question asking you to find?
How can you use similarity to solve this problem?
Is there something in this room that you can use to compare to the monument?
What parts do you need to compare?
Do you have any math tools that can help you gather information?
