Objectives

Duration: (10 - 15 minutes)

The purpose of this step is to provide a clear and concise view of what will be learned during the lesson, aligning the objectives with the development of specific math skills needed to recognize and work with fractions of different denominators. Additionally, this step aims to prepare students emotionally for the lesson, highlighting the importance of recognizing and regulating their emotions when facing new math challenges.

Main Goals

1. Understand the concept of equivalent fractions and their application in finding common denominators.

2. Recognize fractions with different denominators and convert them to the same denominator.

Introduction

Duration: (15 - 20 minutes)

Emotional Warm-up Activity

Deep Breathing for Concentration

The emotional warm-up activity is the practice of Deep Breathing. This technique helps students focus on the present moment, promoting greater concentration and presence. Deep breathing is an effective way to reduce stress and anxiety, allowing students to feel calmer and more prepared to learn new math concepts.

1. Ask students to sit comfortably in their chairs, with their feet firmly on the ground and their hands resting on their knees.

2. Explain that the deep breathing activity will help calm the mind and prepare for the lesson.

3. Instruct students to close their eyes slowly and focus on their breathing.

4. Guide them to inhale deeply through their nose, counting slowly to four.

5. Ask them to hold their breath for a brief moment, counting to four again.

6. Then, ask them to exhale slowly through their mouth, counting to four.

7. Repeat the cycle of inhalation, retention, and exhalation five to ten times, always maintaining a slow and steady rhythm.

8. After the last exhalation, ask students to open their eyes slowly and pay attention to their state of calm and focus.

Content Contextualization

Fractions are an essential part of mathematics and our daily lives. Imagine that you and your friends want to share a pizza equally, but some slices are larger than others. To ensure that everyone receives the same amount, we need to understand how to work with fractions and find common denominators. This skill is also useful in many other situations, such as splitting expenses for a trip or measuring ingredients for a recipe. Furthermore, learning to deal with fractions can be challenging, and recognizing our emotions during this process can help us maintain calm and focus, facilitating learning.

Development

Duration: (60 - 75 minutes)

Theoretical Framework

Duration: (20 - 25 minutes)

1. Definition of Equivalent Fractions: Explain that equivalent fractions are fractions that represent the same part of a whole, even if their numerators and denominators are different. For example, 1/2 is equivalent to 2/4 and 3/6.

2. Method for Finding Equivalent Fractions: Detail how to multiply or divide both the numerator and denominator by the same number to create equivalent fractions. Use examples to illustrate, such as multiplying 1/3 by 2/2 to obtain 2/6.

3. Recognizing Different Denominators: Teach students to identify when two fractions have different denominators. Use examples like 1/4 and 1/6.

4. Finding the Least Common Multiple (LCM): Explain the concept of LCM and how it is used to find a common denominator. For example, for the fractions 1/4 and 1/6, the LCM of 4 and 6 is 12.

5. Converting Fractions to the Same Denominator: Show how to convert fractions to have the same denominator using the LCM. For example, 1/4 = 3/12 and 1/6 = 2/12.

6. Examples and Practical Exercises: Provide additional examples and ask students to practice converting fractions to common denominators and checking if they are equivalent.

Socioemotional Feedback Activity

Duration: (25 - 30 minutes)

Equivalent Fractions Game

Students will be divided into small groups and will receive cards with different fractions. They will work together to find equivalent fractions and convert them to the same denominator, using the concept of equivalent fractions and the LCM.

1. Divide students into groups of 3 to 4 people.

2. Distribute a set of cards with different fractions to each group.

3. Instruct the groups to identify equivalent fractions and find the common denominator for the fractions in the set.

4. Ask the groups to use the LCM to convert the fractions to the same denominator.

5. After conversion, each group should present their equivalent fractions and common denominators to the class.

6. During the presentation, encourage students to explain the process they used to find equivalent fractions and common denominators.

Group Discussion

After the activity, gather all students for a group discussion. Use the RULER method to guide the discussion. First, Recognize the students' emotions during the activity by asking how they felt working in a group and facing math challenges. Understand the causes of these emotions by exploring why certain moments were more challenging or easier. Name the emotions accurately, helping students identify feelings such as frustration, joy, or relief. Then, encourage students to Express their emotions appropriately, sharing their experiences and feelings with the group. Finally, help them Regulate these emotions by suggesting strategies to deal with frustrations and anxieties in future activities. Promote a supportive environment where students feel comfortable sharing and learning from their emotional experiences.

Conclusion

Duration: (20 - 25 minutes)

Emotional Reflection and Regulation

To initiate reflection and emotional regulation, ask students to gather in a circle and share their experiences about the challenges faced during the lesson. Encourage them to be honest about how they felt dealing with fractions and finding common denominators. Alternatively, request that they write a brief paragraph about their emotions and strategies used to overcome difficulties. Ask how they felt working in a group, if there were moments of frustration or joy, and how they managed those emotions.

Objective: The objective of this activity is to encourage self-assessment and emotional regulation among students. By reflecting on the challenges faced and the emotions felt, students can identify effective strategies for dealing with similar situations in the future. This strengthens the ability to recognize, understand, name, express, and regulate emotions, promoting a healthier and more productive learning environment.

Closure and A Look Into The Future

For the closure, ask students to define personal and academic goals related to the lesson content. Explain that these goals can be about improving their understanding of fractions, practicing more exercises at home, or even collaborating better in group activities. Encourage students to write down these goals and share them with the class if they feel comfortable. This helps create a sense of commitment and responsibility for their own learning.

Possible Goal Ideas:

1. Improve understanding of equivalent fractions.

2. Practice converting fractions to common denominators.

3. Develop teamwork skills.

4. Enhance the ability to recognize and regulate emotions during challenging activities. Objective: The objective of this subsection is to strengthen students' autonomy and the practical application of learning. By setting personal and academic goals, students can visualize a clear path for continuing their development both academically and emotionally. This not only reinforces the content learned but also promotes ongoing growth and a proactive attitude towards their own learning.
