Nautical Mile | Math Lesson Plan
Support Materials
About
Students will be able to demonstrate their understanding and usefulness of an earlier measurement of the nautical mile prior to its size reduction and official adoption as the International Nautical Mile in 1953. With meter/foot conversions to help them stay informed, students will learn to use a method to obtain Earth’s radius and circumference. During this process, students will gain experience in finding the number of feet and the number of arc minutes in earth’s circumference and how these results will lead them to the nautical mile.
