Before you can read any language, you must be able to read the symbols that the language is made up of. Learning Roman numerals is no different because the symbols that are used for numbers are not the symbols that most of the world currently uses to represent numbers.
Use this second lesson plan in the series about Roman numerals to teach your student how to interpret each numeral on its own before moving on to the next lesson plan which will tell students how to correctly read Roman numerals and interpret them. Use the information below to explain to students what each Roman numeral and symbol stands for.

This list will teach students what each Roman numeral stands for and provide tips on remembering why each symbol represents what it does.
- I -stands for "1" and can be remembered by remembering that a finger represents the number 1.
- V -stands for "5" and can be remembered by imagining an out stretched hand.
- X – stands for "10" and can be remembered by imaging two hands crossing over each other.
- L -stands for "50". Get creative with this one and think of money. If "X" means ten and thus two hands crossed, remember "L" is fifty by imaging that you must slide one crossed hand down to make room for more money in the palm.
- C – stands for "100" and can be remembered as the $100 bill being called a C-note.
- M- stands for "1000" and can be remembered as the single largest symbol that stands on its own in Roman numerals.
Using the information above, ask students to write the Roman numerals as you name them. Then ask them for possible answers as to how the numbers below might be written.
