Conversions between inches, feet, and yards (4th and 5th grade math)

Measurement conversions here... I explain how to change (convert) between an amount in feet an inches, and inches, such as 4 ft 6 in to inches. Then, we do it the other way around: an amount in inches into feet & inches, such as 56 in. to feet and inches. We do the same with yards & feet to feet, and feet to yards & feet. Then we solve some word problems involving the perimeter of shapes, where the side lengths are given in feet & inches, or yards & feet. Lastly I touch a little bit on miles. We calculate how many feet are in 5 miles, and use estimation to figure about how many miles tall is Mt. McKinley. This video is meant for 4th and 5th grade.
