Learning Objectives

Indicator: B4.1.1.2.1 - Develop an understanding of Roman Numeral system up XXX (i.e. 30)

By the end of the lesson, learners can:

Identify the Roman numeral symbols I, V, and X and state their values (1, 5, and 10).
Read Roman numerals from I to XXX when displayed on a chart or written on the board.
Match Roman numerals to their corresponding Hindu-Arabic numerals (for example, V = 5, X = 10, XV = 15).
Point to a given Roman numeral on a chart when the teacher calls it out.
Explain the pattern used to build Roman numerals from 1 to 30 (for example, why 4 is IV and not IIII, and why 9 is IX and not VIIII).

Exemplars (from the NaCCA curriculum)

E.g. 1 Display Roman numeral charts (1-30) arranged in sequential order and lead learners to identify the numerals. Learners identify the main characters of the roman numerals used to build the table up to 30 i.e. I, II, III, IV, V, X, Call out a numeral and have learners point at it from the chart
E.g. 2 Have learners match the Roman numerals to the Hindu-Arabic numerals for instance I = 1; V= 5: X= 10, XV= 15. Mention some numerals randomly and have learners point at it on the chart
