Roman numerals, the numeric system used in ancient Rome, employs combinations of letters from the Latin alphabet to signify values. The Roman numeral system is a cousin of Etruscan numerals. Use of Roman numerals continued after the decline of the Roman Empire. From the 14th century on, Roman numerals began to be replaced in most contexts by more convenient Hindu-Arabic numerals.
Roman numerals math (my kids know how to read Roman numerals from their McGuffey’s lessons; use Popsicle sticks on the table) Big hit with 8 and 10 year old; we went up to 11. I handed 8yo the total number of sticks she would need to form into shape. However, she can read Roman numerals easily; today she read “49” in her McGuffey’s. Each number is a little equation: 1,2,3, are easy, teach that V is five, so 4 is “1 before 5 or I before V”, 6 is one after 5 or I after V = VI, etc

Roman Numerals: My secret weapon for teaching Roman numerals...toothpicks! I give each student about 10 toothpicks. (I have them already in baggies, and have been using the same set for years.) Then, they practice making the numbers that I call out. I model the numbers on the overhead projector using kabob type sticks. I let them come up and make the numbers on the overhead with my "big toothpicks" as well. Fun way to teach Roman numerals!
