3. Develop the ability to recognize and name emotions related to the learning of new mathematical concepts.

Introduction

Duration: 20 to 25 minutes

Emotional Warm-up Activity

🌟 Mindfulness Moment to Start the Class

Mindfulness practice is a technique of focused attention that helps improve students' focus, presence, and concentration. Involving conscious awareness of the present moment, this activity promotes a state of calmness and receptivity, which is essential for effective learning.

1. Environment Preparation: Ask students to sit comfortably in their chairs, with their feet on the floor and their hands resting on their legs. Ensure that everyone is in a relaxed position.

2. Initial Guidance: Briefly explain to the students what mindfulness is and how the practice can help them maintain focus and calmness during the class.

3. Breathing Exercise: Instruct the students to close their eyes or to fix their gaze on a point in front of them. Ask them to take a deep breath through their nose, filling their abdomen with air, and then exhale slowly through their mouth. Repeat this deep breathing three times.

4. Body Awareness: Ask students to focus their attention on different parts of their bodies, starting from the feet and moving up to the head. Guide them to notice any tension and to release it during exhalation.

5. Breathing Awareness: Ask the students to return their attention to their natural breathing, observing the rhythm and depth of their inhales and exhales. Guide them to notice how their bodies move with each breath.

6. Closure: After a few minutes, ask the students to slowly open their eyes and return their attention to the classroom. Ask how they felt during the practice and encourage them to share their experiences.

Content Contextualization

Polygons are present in various areas of our daily lives, from the architecture of buildings to the design of everyday objects. Understanding the construction and properties of these geometric elements may seem challenging, but it is fundamental for the development of mathematical and spatial skills. By learning about polygons, students not only gain technical knowledge but also develop the ability to solve problems creatively.

Additionally, the construction of algorithms to draw regular polygons is an excellent opportunity for students to practice logical and structured thinking. This process can be compared to decision-making in real life, where it is necessary to plan, follow specific steps, and adjust strategies as needed. Thus, by studying polygons, students are also enhancing their socioemotional skills, such as patience, resilience, and teamwork.

Development

Duration: 60 to 75 minutes

Theoretical Framework

Duration: 20 to 25 minutes

1. Definition of Polygons: Explain to the students that a polygon is a flat geometric figure formed by a sequence of line segments that meet only at their endpoints, forming a closed path.

2. Regular Polygons: Detail that a regular polygon is one that has all sides and internal angles equal. Examples include equilateral triangles, squares, and regular hexagons.

3. Classification of Polygons: Classify polygons according to the number of sides: triangle (3 sides), square (4 sides), pentagon (5 sides), hexagon (6 sides), and so on.

4. Properties of Regular Polygons: List the essential properties of regular polygons, such as symmetry, internal angles, and relationships between sides and angles.

5. Construction of Regular Polygons: Explain the process of constructing a regular polygon based on the measure of one side using a ruler and compass. Provide a step-by-step example for constructing a regular hexagon.

6. Algorithms and Flowcharts: Introduce the concepts of algorithms and flowcharts. Explain that an algorithm is a well-defined sequence of steps to solve a problem, and a flowchart is a graphical representation of these steps.

7. Example Flowchart: Draw a simple flowchart for constructing an equilateral triangle, highlighting each step of the process.

Socioemotional Feedback Activity

Duration: 35 to 40 minutes

🔺 Construction of Regular Polygons

In this activity, students will apply the concepts learned to create an algorithm and a flowchart for constructing a regular polygon, given the side length. The activity will be divided into groups, promoting collaboration and communication among students.

1. Group Division: Organize the students into groups of 3 to 4 members.

2. Polygon Definition: Each group will choose a type of regular polygon (equilateral triangle, square, pentagon, hexagon, etc.).

3. Algorithm Development: Ask the groups to develop a detailed algorithm for constructing the chosen polygon, specifying each necessary step.

4. Flowchart Creation: Instruct the groups to draw a flowchart that represents the created algorithm. The flowchart should include all steps, from measuring the sides to completing the polygon.

5. Presentation of Results: Each group will present their algorithm and flowchart to the class, explaining each step and showing the constructed polygon.

6. Socioemotional Feedback: After the presentations, lead a group discussion using the RULER method.

Group Discussion

After the activity, gather the students for a group discussion about their experiences. Recognize the emotions that arose during the activity by asking students how they felt working in groups and facing challenges in constructing the algorithms. Understand the causes of these emotions by encouraging students to reflect on what caused feelings of frustration, joy, or satisfaction.

Name the emotions accurately, helping students to identify terms such as 'anxiety', 'pride', or 'confusion'. Encourage them to express their emotions appropriately, sharing their experiences and listening to peers with empathy. Finally, discuss ways to regulate these emotions in the future, suggesting techniques such as deep breathing or asking for help when necessary.

Conclusion

Duration: 15 to 20 minutes

Emotional Reflection and Regulation

To conclude the class, promote a reflection, which can be written or in the form of a group discussion. Ask students to describe the challenges faced during the construction of the polygons and the creation of algorithms and flowcharts. Inquire how they managed their emotions throughout the activity and what strategies they employed to maintain calmness and concentration. Encourage them to share how they felt working in teams and how they dealt with possible frustrations or difficulties.

Objective: The objective of this subsection is to encourage self-assessment and emotional regulation, helping students identify effective strategies for dealing with challenging situations. By reflecting on their experiences, students can develop greater awareness of their emotions and learn to regulate their reactions more efficiently, which is essential for both academic and personal contexts.

Closure and A Look Into The Future

To close the class, explain to students the importance of setting personal and academic goals related to the content learned. Encourage them to establish clear objectives, such as improving accuracy in constructing polygons, increasing confidence in developing algorithms, or enhancing group collaboration. Emphasize how these goals can be achieved with practice and continuous effort, and how they can contribute to the development of mathematical and socioemotional skills.

Possible Goal Ideas:

1. Improve accuracy in constructing regular polygons.

2. Increase confidence in developing algorithms.

3. Enhance collaboration and communication in groups.

4. Develop resilience when faced with mathematical challenges.

5. Apply emotional regulation strategies in stressful situations. Objective: The objective of this subsection is to strengthen students' autonomy and practical application of learning, encouraging them to continue developing their academic and personal competencies. Setting clear goals helps students maintain focus and motivation, promoting constant and significant progress in their mathematical and socioemotional skills.
