 # Roman Numerals 1 to 100 (1)

In this worksheet, students must convert Roman Numerals to normal numbers up to 100. Key stage:  KS 2

Curriculum topic:   Number: Number and Place Value

Curriculum subtopic:   Read Roman Numerals (I to C/1 to 100)

Difficulty level:   ### QUESTION 1 of 10

The numbers that we use today are not the same as the ones the Romans used.

Roman Numerals were used all over the Roman Empire.

In England, they are still used occasionally, for example, on film credits and clock faces.

Remember that the Romans didn't have a symbol for the number 0.

The Romans used these symbols:

I  = 1

V = 5

X = 10

L = 50

C = 100

All other numbers up to 100 can be built using these symbols by adding or subtracting.

You should know the following:

 1 I 2 II 3 III 4 IV I before V is 1 less than 5 5 V 6 VI I after V is 1 more than 5 7 VII II after V is 2 more than 5 8 VIII III after V is 3 more than 5 9 IX I before X is 1 less than 10 10 X 11 XI I after X is 1 more than 10 12 XII II after X is 2 more than 10

We build bigger numbers by adding 10s or Xs in Roman Numerals.

 20 XX = X + X = 20 21 XXI = XX + I = 20 + 1 30 XXX = X + X + X = 30 37 XXXVII = XXX + VII = 30 + 7 40 XL = X before L is 10 less than 50 or 50 - 10 = 40 48 XLVIII = XL + VIII = 40 + 8 = 48 49 XLIX = XL + IX = 40 + 9 = 49 50 L 54 LIV = L +IV = 50 + 4 = 54 60 LX = X after L is 10 more than 50 or 50 + 10 = 60 67 LXVII = LX + VII = 60 + 7 = 67 70 LXX = L + XX = 50 + 20 = 70 80 LXXX = L + XXX = 50 + 30 = 80 84 LXXIV = L + XXXIV = 50 + 34 = 84 90 XC = X before C is 10 less than 100 or 100 - 10 = 90 96 XCVI = XC + VI = 90 + 6 = 96

Example

Convert XCIV and LXXIX to normal numbers.

XCIV = XC + IV = 90 + 4 = 94

LXXIX = L + XXIX = 50 + 29 = 79
