CONTENT OF THE LESSON

ROMAN NUMERALS (I – C)

Basic Application 

Examples

1 = I

2 = II

3 = III

4 = 5 – 1 = V – I = IV,

 

Note

Rule number 1,

  • When a larger symbol comes after the smaller symbol, it is substation. That is, IV = V – I = 4

5 = V

6 = V + I = VI

 

Rule number 2,

  • When a smaller symbol comes after the larger symbol, it is addition. That is, V + I = 6.

Rule number 3,

 

  • Don’t use the same symbol more than three times in a row.

 

Exercise 1

Read Roman numerals from 11 – 19.

 

Exercise 2

Write Roman numerals from 21 – 30.

  2. Guides pupils to use fingers to represent numbers in Roman numerals I – X (1 to 10);
  3. Guides pupils to form Roman numeral – I (one finger), V (five fingers), X (ten fingers);
  4. Pupil’s Activities – Read and write Roman numerals up to 10.;
  5. Uses Roman numeral chart to lead pupils to read and write the Roman numerals I to C;
  6. Pupil’s Activities – Study the Roman numerical chart and flash cards.
  7. Pupil’s Activities – Practice the number formation system for Roman numerical ( I × C) using fingers.
  8. Pupil’s Activities – Write all the Roman numerals I to C in their exercise book.
