Roman Numerals worksheet with exercises for converting number words to Roman numerals and matching Roman numerals to numbers.

Let’s solve this step by step.

First, we need to write the Roman numeral for each number word.

Remember these basic Roman numerals:
- I = 1
- V = 5
- X = 10
- L = 50 (we won’t need it here)
- C = 100 (not needed either)

Now let’s go one by one:

1. three → III
2. seven → VII (5 + 2 = V + II)
3. twelve → XII (10 + 2 = X + II)
4. one → I
5. fifteen → XV (10 + 5 = X + V)
6. five → V
7. twenty → XX (10 + 10 = X + X)
8. eleven → XI (10 + 1 = X + I)
9. thirteen → XIII (10 + 3 = X + III)
10. twenty five → XXV (20 + 5 = XX + V)

Now, the second part: choose the correct number that each Roman numeral represents.

We’ll break down each Roman numeral:

- II → I + I = 1 + 1 = 2
- IV → V - I = 5 - 1 = 4 (when a smaller number is before a bigger one, subtract!)
- XXIII → X + X + I + I + I = 10 + 10 + 1 + 1 + 1 = 23
- XVIII → X + V + I + I + I = 10 + 5 + 1 + 1 + 1 = 18
- VIII → V + I + I + I = 5 + 1 + 1 + 1 = 8
- XVI → X + V + I = 10 + 5 + 1 = 16
- XIV → X + IV = 10 + 4 = 14 (again, IV means 4)
- XXII → X + X + I + I = 10 + 10 + 1 + 1 = 22
- X → just 10

Now let’s match them with the choices given in the worksheet.

For “II” → options are 2, 5, 1 → pick 2

For “IV” → options are 5, 4, 9 → pick 4

For “XXIII” → options are 42, 23, 25 → pick 23

For “XVIII” → options are 18, 28, 13 → pick 18

For “VIII” → options are 7, 8, 9 → pick 8

For “XVI” → options are 16, 12, 15 → pick 16

For “XIV” → options are 14, 15, 16 → pick 14

For “XXII” → options are 12, 23, 22 → pick 22

For “X” → options are 10, 5, 20 → pick 10
