Warming Up

Warm-up:

Start the lesson by introducing the topic 'Proportional Relationships' in an introductory manner. Explain that in mathematics, proportionality is a relationship that shows how two quantities vary together. Emphasize that this relationship is essential in various everyday contexts, such as vehicle speeds, ingredient proportions in recipes, or plant growth.

🚀 Instruct students to use their phones to search for and share an interesting fact about 'Proportional Relationships'. This can be a historical curiosity, a practical application in technology or science, or even an example they found on social media. Emphasize the importance of connecting the concept to real and modern situations.

Initial Reflections

1. What does it mean to say that two quantities are proportional?

2. Can you give an example of proportionality that you observed in your daily life?

3. How do you explain the proportionality constant in simple terms?

4. How is the speed of a car an example of proportionality between distance and time?

5. Are there situations where the quantities are not proportional? Give an example.

Development

Duration: (85 - 90 minutes)

The purpose of this lesson plan stage is to allow students to apply their knowledge of proportional relationships in practical and contextualized situations, using modern technologies and working collaboratively. This will strengthen the understanding of theoretical concepts through practice and engagement in dynamic and fun activities.

Activity Suggestions

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

Activity 1 - 🔍 The Digital Proportionality Treasure Hunt

> Duration: (60 - 70 minutes)

- Objective: Apply the concept of proportionality in different contexts and develop teamwork and problem-solving skills.

- Description: Students will be divided into groups. Each group will participate in an online 'treasure hunt', solving a series of puzzles and challenges involving proportional relationships. Using their phones and computers, they will need to access different websites and apps to find clues and solve problems. All challenges will be connected through a gamification platform that will track each group's progress.

- Instructions:

• Divide students into groups of up to 5 people.

• Explain that each group will have to follow a series of clues found online to solve proportionality problems.

• Instruct students to access a gamification platform where each clue will be released after solving the previous puzzle.

• Each challenge must be solved within a time limit to advance to the next stage.

• The group that solves all the puzzles first will be the winner of the 'treasure hunt.'

Activity 2 - 🎥 The Math Influencer

> Duration: (60 - 70 minutes)

- Objective: Promote understanding of the concept of proportionality in a creative and engaging way, using communication skills and digital tools.

- Description: Each group of students will be responsible for creating a short video, in the style of a digital influencer, teaching the concept of proportionality to other students. They should use creativity and digital resources, such as visual effects and animations, to make the video appealing and educational. The videos will be posted on a school video-sharing platform and evaluated by both peers and teachers.

- Instructions:

• Form groups of up to 5 students.

• Explain that each group must create a 3 to 5 minute video explaining the concept of proportionality.

• Provide tips on how to use video editing tools and special effects to make the video more engaging.

• Students should plan the script, record, and edit the video during class time.

• After completion, the videos should be posted on the school video-sharing platform.

• The videos will be evaluated based on creativity, clarity of explanation, and use of digital resources.

Activity 3 - 🌍 Mission Mars: Proportionality in Space

> Duration: (60 - 70 minutes)

- Objective: Apply the concepts of proportionality in a planning and simulation context for a space mission, developing problem-solving and critical thinking skills.

- Description: Students will be divided into groups and will have to plan a space mission where they need to calculate the proportion between different variables, such as fuel, travel time, and distance. Using an online space mission simulator, each group must adjust their variables to ensure the success of a fictional mission to Mars.

- Instructions:

• Divide students into groups of up to 5 people.

• Explain that each group will be responsible for planning a space mission using an online simulator.

• Each group will need to calculate proportions among different variables, such as the amount of fuel needed, travel time, and distance to Mars.

• Students must adjust these variables in the simulator to ensure the mission is successful.

• The group that achieves the most efficient mission (least fuel use, shortest travel time) will be the winner.

Feedback

Duration: ⏳ Duration: (15 - 20 minutes)

🎯 Purpose: The purpose of this lesson plan stage is to consolidate students' learning through reflection and sharing experiences. By discussing in groups and providing constructive feedback, students develop communication, collaboration, and critical thinking skills, reinforcing their understanding of the concepts of proportionality in a practical and modern context.

Group Discussion

📢 Group Discussion: Promote a group discussion with all students, where groups share what they learned from the experience and their conclusions. Suggest that each group prepare a brief presentation of 2-3 minutes highlighting the main challenges faced, how they overcame them, and what they discovered about proportional relationships. Guide students to focus on the practical applications of the concept that they encountered during the activities.

Reflections

1. 🔍 Reflection Questions: - What was most challenging about applying the concept of proportionality in practical activities? - How can the concepts of proportionality be seen in other areas of knowledge or in everyday situations? - What strategies or digital tools were most useful for solving the proposed problems?

360° Feedback

🗣 360° Feedback: Instruct the teacher to conduct a 360° feedback stage where each student must receive feedback from their group peers regarding the activity they worked on. Guide students to focus on constructive aspects such as: - What did this peer do well during the activity? - How could this peer improve in future activities? - What was this peer's most significant contribution to the group? Emphasize the importance of respectful and objective feedback, fostering a collaborative learning environment.

Conclusion

Duration: (10 - 15 minutes)

🎯 Purpose: The conclusion stage aims to consolidate acquired knowledge, connect learning to the real world, and highlight the practical importance of the content.
