Lesson Plan | Active Methodology | Roman Numerals

Premises: This Active Lesson Plan assumes: a 100-minute class duration, prior student study both with the Book and the beginning of Project development, and that only one activity (among the three suggested) will be chosen to be carried out during the class, as each activity is designed to take up a large part of the available time.

Objective

Duration: (5 - 10 minutes)

The objectives stage is essential for guiding the focus of the lesson and clearly outlining the expectations for what students should achieve by the end of the session. By setting specific goals, students gain a clearer understanding of what they need to learn and why it matters. This stage also helps align expectations and ensure that both students and the teacher are working towards the same aims.

Objective Utama:

1. Empower students to appreciate the significance of the decimal system as the primary numerical framework used globally.

2. Develop proficiency in converting between Roman numerals and the decimal system, both in reading and writing.

3. Enable students to tackle practical problems involving Roman numerals, such as reading digital clocks or house numbers.

Objective Tambahan:

1. Spark students' curiosity about the history and applicability of Roman numerals in everyday scenarios.
2. Encourage collaboration and discussion among students during group activities.

Introduction

Duration: (15 - 20 minutes)

The aim of the introduction stage is to engage students through problem scenarios that prompt them to apply their existing knowledge of Roman numerals, setting the stage for practical classroom activities. Additionally, by contextualizing the relevance of the topic with relatable examples and historical tidbits, we aim to elevate curiosity and understanding of the practical and cultural significance of Roman numerals.

Problem-Based Situation

1. Imagine you're playing a board game and need to move 15 spaces. However, the spaces are numbered using Roman numerals. How would you convert the number 15 into Roman numerals to progress in the game?

2. In history class, your teacher asks you to look at the date on an old document, which is written in Roman numerals. The date is 1715. How can you convert this date into the decimal format we use every day?

Contextualization

Roman numerals, though less common today as a practical numerical system, still find use in significant contexts like numbering book chapters, in movie titles, and on clocks and historical monuments. Moreover, grasping Roman numerals can prove useful in board games, which often incorporate this system, and in cultural contexts involving ancient inscriptions. Interestingly, Roman numerals lack a zero, which makes them fascinating from both historical and mathematical viewpoints.

Development

Duration: (65 - 75 minutes)

The development stage aims to put the knowledge students have acquired regarding Roman numerals into practice. By collaborating in groups, they reinforce their individual learning, while also honing teamwork and communication skills. Each activity approaches Roman numerals in unique and creative ways, ensuring a thorough and applied grasp of the topic.

Activity Suggestions

It is recommended that only one of the suggested activities be carried out

Activity 1 - Roman Numerals Challenge

> Duration: (60 - 70 minutes)

- Objective: Enhance skills in switching between Roman numerals and the decimal system in a practical, collaborative environment.

- Description: Students will work in groups of up to 5, tackling a series of challenges that involve converting numbers between the decimal system and Roman numerals. Each group must complete a set of 10 problems that range from straightforward to more intricate, using paper and pencil.

- Instructions:

• Form groups of up to 5 students.

• Hand out worksheets with 10 problems to each group.

• Each problem should be solved on paper, showing both the conversion process and the final result in Roman numerals.

• Utilize available resources like lists of Roman numerals to aid in solving the problems.

• After 30 minutes, each group will present one problem and its solution, explaining the reasoning behind their approach.

Activity 2 - Building a Roman Numerals Clock

> Duration: (60 - 70 minutes)

- Objective: Put knowledge of Roman numerals into practice while fostering teamwork.

- Description: In this group activity, students will construct a paper clock that features Roman numerals for the hours. They'll need to convert numbers from the decimal system to Roman numerals as they build the clock.

- Instructions:

• Organize students into groups of up to 5.

• Provide each group with construction materials (paper, cardboard, markers, etc.).

• Start with a discussion about the history and significance of Roman numerals in clock-making.

• Each group will convert the hours from 1 to 12 into Roman numerals and mark them on their paper clock.

• After they assemble their clocks, each group will explain their conversions and clock assembly to the class.

Activity 3 - The Caesar Code

> Duration: (60 - 70 minutes)

- Objective: Encourage critical thinking and the playful application of Roman numerals.

- Description: In this group activity, students will engage in a cryptography exercise using Roman numerals to encode and decode messages, simulating a secret code based on this numbering system.

- Instructions:

• Divide the class into groups of up to 5 students.

• Introduce the concept of cryptography and how Roman numerals can be used as a coding mechanism.

• Distribute cards with phrases encoded in Roman numerals that each group will need to decipher.

• Instruct each group to create their own encoded message using Roman numerals.

• Finally, have groups attempt to decode a message crafted by another group.

Feedback

Duration: (15 - 20 minutes)

This stage is meant to give students a platform to articulate and reflect on their learning from the practical activities, reinforcing the knowledge they've garnered. The discussion also promotes the exchange of ideas and collaborative learning, while providing an opportunity for the teacher to assess understanding and address any lingering questions.

Group Discussion

At the end of the activities, arrange a class discussion. Begin with: 'Now that we've wrapped up the activities, let's share our experiences and insights. Each group will have the chance to summarize what they learned while working with Roman numerals and how they applied this knowledge to the activities.'

Key Questions

1. What were some of the main challenges you encountered while converting between decimal and Roman numerals?

2. In what everyday situations or across different subjects can understanding Roman numerals be beneficial?

3. Did you come across any surprising facts or curiosities about Roman numerals that you'd like to share?

Conclusion

Duration: (5 - 10 minutes)

The conclusion stage is meant to solidify what students have learned, ensuring they have a clear grasp of the topics covered and the skills acquired. Furthermore, it underscores the practical and cultural significance of Roman numerals, motivating students to implement their newfound knowledge across different contexts. This final reflection helps ensure that the concepts learned are both retained and appreciated by the students.

Summary

In this final segment, the teacher should recap the main points addressed during the lesson, reiterating the significance of converting between Roman numerals and the decimal system and emphasizing the practical uses of Roman numerals in various contexts such as clocks, chapter numbering, and historical references.

Theory Connection

The teacher should illustrate how hands-on activities, such as the board game and clock construction, reinforced theoretical knowledge of Roman numerals, highlighting the link between theory and practice. This approach not only enhances comprehension but also allows students to grasp the real-world relevance of what they have learned.

Closing

To wrap things up, it’s crucial to underscore the importance of Roman numerals, not only as a part of culture and history but also as essential knowledge applicable in daily life. Being able to understand and use Roman numerals can be advantageous in a variety of situations, from interpreting inscriptions on monuments to grasping foundational concepts in other subjects.
