Roman Numbers

Practice converting between Arabic and Roman numbers

If there is one alternative number systems everyone should learn, it’s the Roman number system. It’s the only other number system used today, although it’s usually only found in decorative or customary locations, such as clocks, inscriptions and movie credits. If possible, find something in regular use that displays a Roman number and start a discussion with the students about why it might have been designed that way.

This worksheet provides three different exercises having to do with Roman number conversion. The first two provide practice in converting from and to the Roman number system. The third is a math problem expressed in Roman. The student will have to convert the values to Arabic, compute the answer, then convert the answer back into Roman.
