Last week, we mentioned that we completed telling the stories of the Five Great Lessons. The Fifth Great Lesson: How Numbers Began has prompted us to start a new unit in History. This new unit is based on Roman Numerals and Egyptian Numeration. The Romans used seven capital letters of the alphabet to stand for numbers. I, V, X, L, C, D, and M were used to represent the numbers 1, 5, 10, 50, 100, 500, and 1,000. The ancient Egyptians used a form of picture writing called hieroglyphics to write their numerals. They used seven different symbols to show numbers and could combine them to show small and large numbers. This unit has always been a favorite of students past and will more than likely be for our current students.
