This section allows students to practice and solidify their understanding of Roman numerals through engaging and interactive activities. Taking a hands-on approach helps clarify the rules of formation and number conversion while also enhancing collaboration and teamwork.

Topics

1. History and Origin of Roman Numerals

2. Rules for Forming Roman Numerals

3. Converting Decimal Numbers to Roman Numerals

4. Converting Roman Numerals to Decimal Numbers

5. Real-life Applications of Roman Numerals

Thoughts on the Subject

Encourage students to think about how Roman numerals are present in various everyday situations—on clocks, in historic monuments, and in films. Ask them what it would be like if we only used Roman numerals today, along with the challenges and advantages of such a practice.

Mini Challenge

Creating a Clock with Roman Numerals

In this hands-on activity, learners will design a model clock featuring Roman numerals to denote the hours. This activity allows students to apply their knowledge of converting decimal numbers into Roman numerals within a practical context.

1. Split the students into groups of 3 to 4 members.

2. Provide each group with materials such as poster board, markers, rulers, and compasses.

3. Direct them to draw a large circle on the poster board to serve as the clock's base.

4. Guide students in dividing the circle into 12 equal parts using the ruler and compass.

5. Each group should write the numbers 1 to 12 in Roman numerals in the designated sections.

6. After noting down the numbers, students should decorate the clock according to their creativity.

7. Encourage them to discuss among themselves during the activity, fostering collaboration and teamwork.

Develop the skill to convert decimal numbers to Roman numerals and apply this knowledge through a practical and cooperative activity.

**Duration: (30 - 40 minutes)

Evaluation Exercises

1. Convert the following decimal numbers to Roman numerals: 5, 14, 29, 44, 58.

2. Convert the following Roman numerals to decimal numbers: IV, XIX, XXXIII, XLII, LV.

3. Identify and correct any errors in the following Roman numeral representations: IIX, IXI, VVII, XIIX.

4. In groups, determine the Roman numeral for a house numbered 47.

5. Draw a clock face with Roman numerals and mark the hours 3, 6, 9, and 12 accurately.

Conclusion

Duration: (10 - 15 minutes)

The aim of this final segment is to reinforce the knowledge students have gained, emphasizing the connection between theory and practice. The concluding discussion and reflection will help students internalize what they have learned, share their experiences, and appreciate the significance of the topic in their daily lives and future careers.
