Adapted from:
http://www.pbs.org/teachers/mathline/lessonplans/msmp/noses/noses_procedure.shtm
Standards Addressed:
MCC6.RP.1 Understand the concept of a ratio and use ratio language to describe a ratio
relationship between two quantities.
MCC6.RP.3 Use ratio and rate reasoning to solve real-world and mathematical problems, e.g. by
reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or
equations.
MCC6.RP.3d Use ratio reasoning to convert measurement units, manipulate and transform units
appropriately when multiplying or dividing quantities.
1. Measure your arm span from finger tip to finger tip. Measure your height. Find the ratio
of your arm span to your height.
2. Measure the length of your foot and the distance around your fist. Find the ratio of the
length of your foot to the distance around your fist.
3. Using the picture of the Statue of Liberty and the fact that her nose measures 4 feet 6
inches from the bridge to the tip, determine the length of the Statue of Liberty’s right
arm, the one holding the torch.
4. What strategy did you use to determine the length of the Statue of Liberty’s right arm?
5. Is the ratio of the measurement of the length of your nose to the length of your arm the
same as the ratio of the Statue of Liberty’s?
