The children learned three basic conversions for customary measurement.
1. 12 inches = 1 foot
2. 3 feet = 1 yard
3. 36 inches = 1 yard
Once they were armed with this information, they were asked to use it. (This part got a little tricky.) If we know there are 12 inches in 1 foot, then we can figure out how many inches are in many feet. Similarly, if we know there are 3 feet in 1 yard, we can figure out how many feet (or inches) are in many yards.
We found it easiest to use a table:
feet 1 2 3
inches 12 24 36
You can practice problems like these at home. Use the table to help!
37 inches = _______ ft. ________ in.
4 ft. 6 in. = _________ in.
