Duration: (10 - 15 minutes)

This stage is aimed at familiarizing students with the topic of permutations with repetition, ensuring a solid understanding of the concepts to be discussed. It also seeks to prepare students for upcoming activities, igniting their interest and curiosity while nurturing their socio-emotional skills, which are crucial for grasping and utilizing the principles of combinatorial analysis.

Objective Utama

1. Clarify the concept of permutations with repetition using relatable examples such as the word 'BANANA'.

2. Enhance the ability to tackle mathematical problems involving permutations with repeated elements.

Introduction

Duration: (15 - 20 minutes)

Emotional Warmup Activity

Deep Breathing for Concentration

Deep breathing is an effective and simple method to boost focus, presence, and concentration among students. By guiding students through a series of controlled breaths, they can calm their minds, alleviate anxiety, and emotionally prepare themselves for the lesson. This practice fosters a peaceful and open learning atmosphere, enhancing students' capacity to grasp and apply new concepts.

1. Begin the activity by having students sit comfortably in their chairs, with their feet flat on the floor and hands resting on their knees.

2. Instruct them to close their eyes and concentrate solely on their breathing.

3. Ask students to take deep breaths through their noses, silently counting to four.

4. Have them hold their breath for a quick moment, again counting to four.

5. Guide them to exhale slowly through their mouths, counting to four once more.

6. Repeat this breathing cycle for about five minutes, encouraging students to pay attention to the sensation of air moving in and out of their lungs.

7. Once the activity concludes, ask them to gradually open their eyes and do some light stretching to reorient themselves to the environment.

Content Contextualization

Combinatorial analysis, particularly permutations with repetition, is a key concept in Mathematics that has real-world applications in our daily lives. For instance, when creating a secure password or arranging different time slots in a schedule, we apply principles of combinatorial analysis. Recognizing how various elements can be arranged, even with repetitions, allows us to make more thoughtful and efficient decisions. Additionally, combinatorial analysis promotes the significance of organization and systematization—skills that are essential both personally and professionally. By mastering these principles, students will not only enhance their mathematical abilities but also cultivate their capacity to solve problems logically and creatively in real-life situations.

1. ### Key Components of Permutations with Repetition

2. Definition of Permutations with Repetition: This refers to the arrangement of a set of elements where some can be repeated, and the formula for calculating these permutations is utilized.

3. Formula: The formula for determining permutations with repetition is: P(n; n1, n2, ..., nk) = n! / (n1! * n2! * ... * nk!), where n represents the total number of elements, and n1, n2, ..., nk denote the quantities of repeated elements.

4. Practical Example: In the case of the word 'BANANA', there are 6 letters in total (n = 6), where B appears once, A appears three times, and N appears twice. Using the formula: P(6; 1, 3, 2) = 6! / (1! * 3! * 2!) = 720 / 12 = 60 possible permutations.

5. Analogies for Better Understanding: Think of permutations as organizing various flavours of ice cream in a cone. If you have repeated flavours, the possible combinations increase.

6. Practical Applications: Outline how permutations with repetition can be utilized in various scenarios such as creating passwords or scheduling, where certain elements may repeat.

7. Emotional Responses Related to the Topic: Discuss how emotions such as anxiety or frustration can emerge when tackling complex problems and strategies for managing those feelings.

Activity with Socioemotional Feedback

Duration: (30 - 35 minutes)

Permuting the Word 'BANANA'

In this activity, students will engage with permutations involving repetition using the word 'BANANA'. They will enumerate all possible permutations and grasp how the repetition of elements influences the total number of combinations.

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

2. Provide each group with paper and a pen.

3. Clarify that they need to identify all possible permutations for the word 'BANANA'.

4. Encourage collaborative discussions among group members as they document all combinations they discover.

5. After 15 minutes, invite each group to present their findings to the class.

Discussion and Group Feedback

🚀 Group Discussion and Feedback: Following the activity, initiate a group discussion employing the RULER method:

Recognize: Encourage students to identify emotions they experienced during the activity, whether it was frustration when they couldn't find all permutations or satisfaction upon completing the task.

Understand: Help students to explore the causes behind these emotions. Frustration might stem from difficulties in understanding the concept, while satisfaction often arises from successful collaboration.

Name: Motivate students to accurately label their emotions, discussing how feelings like anxiety or excitement can affect their performance.

Express: Create a space where students feel comfortable sharing their emotions and experiences with their peers.

Regulate: Introduce emotional regulation techniques, such as practicing deep breaths or seeking assistance from classmates, to help manage feelings during future activities.

Conclusion

Duration: (15 - 20 minutes)

Reflection and Emotional Regulation

🔍 Reflection and Emotional Regulation: Invite students to engage in a written reflection or a group discussion regarding the hurdles they encountered while solving permutation problems with repetition. Pose questions like: What were the most challenging moments? How did you feel during those times? How did you navigate these challenges? Encourage them to share strategies that helped them manage their emotions and how these strategies might be relevant in other tough situations.

Objective: The aim of this activity is to support self-reflection and emotional regulation, helping students identify effective methods for handling challenges. By reflecting on their feelings and actions throughout the lesson, students grow in self-awareness and learn to regulate their emotions more effectively in both academic and everyday scenarios.

Glimpse into the Future

📅 Closure and Looking Ahead: Conclude the lesson by encouraging students to set personal and academic goals related to the material covered. These goals may involve tackling additional problems on permutations with repetition, implementing the concept in everyday scenarios, or developing techniques for better emotional management during challenging tasks.

Penetapan Objective:

1. Work through at least 5 more problems related to permutations with repetition.

2. Incorporate the concept of permutations with repetition in a practical situation, such as designing passwords.

3. Create a personal emotional management technique for use in challenging circumstances.

4. Share the knowledge gained with a classmate or present it in class. Objective: This segment aims to bolster students' independence and the practical application of their learning, encouraging them to keep honing their skills both academically and personally. Establishing clear and attainable goals will help students stay motivated and focused, encouraging ongoing and effective learning.
