The ancient Romans use symbols to represent numbers. We refer to this values as Roman numerals. Many students ask why we even study an ancient form of numeric values. The really answer is that a great many industries have grown to use Roman numerals more than you would every think. Roman numerals are still common in court cases, copyright dating, sporting events, and the naming of modern monarchs. The most common Roman math symbols, you will come across, are: I = 1, V = 5, X =10, L = 50, and C = 100. Learning numbers is a whole lot of fun, especially when we are studying in a new language. It is creative and remarkably interesting! Today, let's take a look at how we write Roman numerals! Generally, in math, we use numbers for denoting the count. But when we are writing numbers in Roman, we use letters. The Roman numbering system is based on seven letters, I, V, X, L, C, D, and M.

These worksheets explain how to read and write Roman numerals and convert between Arabic. Rules for constructing these values are fully included.

Lesson and Practice Worksheet

There are a few basic principles for reading and writing Roman numerals: 1. A letter repeats its value that many times (XXX = 30, CC = 200, etc.). A letter can only be repeated three times. 2. If one or more letters are placed after another letter of greater value, add that amount. VI = 6 (5 + 1 = 6), LXX = 70 (50 + 10 + 10 = 70) 3. If a letter is placed before another letter of greater value, subtract that amount. IV = 4 (5 – 1 = 4), XC = 90 (100 – 10 = 90)
