Warming Up

 Warm-up: Today's lesson will be about Angle Classification. Angles are fundamental to understanding various geometric figures and help us better understand the world around us. Now, ask the students to use their phones to search for and share an interesting fact about angles. It can be a practical application, a curious fact, or a use in technology and engineering.

Initial Reflections

1. ❓ What are the three main types of angles?

2. ❓ How can you identify an acute, obtuse, and right angle in a figure?

3. ❓ Did anyone find an interesting fact about angles during the online search? Share with the class!

4. ❓ In what everyday situations do you encounter these angles?

5. ❓ Why is it important to know how to classify different types of angles?

Development

Duration: 80 - 85 minutes

In this stage, students will apply their prior knowledge of angle classification in a practical and interactive way. The activities have been carefully designed to promote collaborative learning, the creative use of technologies, and the contextualization of content in students' daily lives. The goal is to make the process of learning mathematics more engaging and relevant, stimulating curiosity and critical thinking.

Activity Suggestions

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

Activity 1 -  Angle Detective Mission

> Duration: 60 - 70 minutes

- Objective: Apply the classification of angles in real situations and develop analysis and digital presentation skills.

- Description: In this activity, students will become digital detectives. Each group will find and classify angles in real images of structures or objects accessible via the internet. They will use mobile devices to capture and analyze images, identifying and marking right, acute, and obtuse angles.

- Instructions:

• Divide the class into groups of no more than 5 students.

• Each group should use their phones to research and find images of structures or objects (buildings, bridges, artworks, etc.) that display visible angles.

• Use image editing or annotation apps (such as Canva or Google Drawings) to mark and classify the angles found in the images.

• Each group must identify at least 5 angles in their images and classify them appropriately as right, acute, or obtuse.

• Groups should share the results on a virtual board (such as Padlet or Google Classroom) and make a brief presentation explaining their findings.

• Students must justify their classifications, explaining how they identified each type of angle in the images.

Activity 2 -  Angle Influencers Game

> Duration: 60 - 70 minutes

- Objective: Develop communication, creativity, and critical analysis skills, utilizing digital technologies to teach and learn angle classification.

- Description: Students will transform into digital influencers and create content explaining angle classification. They will use simulated social media (educational tools) to share their videos and compete for the best explanation.

- Instructions:

• Form groups of no more than 5 students.

• Each group must choose a geometric figure and create an explanatory video, using their phones, about how to classify the angles of that figure. They can use simple video editing programs like VivaVideo or InShot.

• The videos should be short (1-2 minutes) and creative, encouraging the use of graphics, animations, and visual effects.

• The videos will be published in a simulated video-sharing platform (like Flipgrid or a shared folder in Google Drive).

• Each group should watch their peers' videos and give constructive feedback, using criteria of clarity, accuracy, and creativity.

• At the end, groups vote on what they consider the best video and discuss the techniques used.

Activity 3 -  Angles Instagram

> Duration: 60 - 70 minutes

- Objective: Encourage the practical application of angle classification in everyday life and develop written and digital communication skills.

- Description: In this activity, students will create a fictional Instagram page where they will post images with different angles found in everyday life. They will classify the angles and create descriptive and interesting captions for each post.

- Instructions:

• Divide the class into groups of no more than 5 students.

• Each group should use their phones to take photos of objects or scenes from everyday life that contain visible angles (it can be around the school or at home).

• Each group creates a fictitious Instagram account (it can be in a simulated educational tool like ClassDojo or Google Slides) to post their images.

• Students should classify the angles in the taken photos as right, acute, or obtuse and write detailed captions for each post, explaining the classification and the importance of the angle in the image.

• The posts will be shared on a common platform for all groups to see and comment on each other's posts, building a collaborative learning network.

• Students discuss the different applications of the angles in the shared images, highlighting the importance of identifying and classifying angles in everyday life.

Feedback

Duration: 20 - 25 minutes

The purpose of this stage is to consolidate learning and promote critical reflection on the activities carried out. The group discussion allows students to share their experiences, learn from each other, and develop communication skills. The 360° feedback strengthens collaboration and encourages a culture of continuous improvement, where everyone helps each other grow and enhance their skills.

Group Discussion

️ Group Discussion: Start the group discussion by asking each group to share what they learned during the practical activities. Ask about the challenges encountered, creative solutions, and the most interesting discoveries. Use the following script to guide the discussion:

1. Ask each group to present a summary of their activities, highlighting the types of angles they found and how they classified them.
2. Encourage students to discuss the practical applications of the angles they identified in their images and videos.
3. Ask about the digital tools used and how they helped in the analysis and presentation process.
4. Promote a discussion about the importance of identifying and classifying angles in everyday life and in different professions.

Reflections

1.  Reflection Questions:

1. How did the activities help reinforce your understanding of angle classification? 2. What were the biggest challenges in identifying and classifying angles in the images and videos? 3. How did the use of digital technologies facilitate or hinder the learning process?

360° Feedback

 360° Feedback: Instruct students to conduct a 360° feedback round, where each group member must provide constructive feedback to their peers. Guide them to ensure that the feedback is specific, highlighting positive points and suggesting improvements in a respectful manner. Here is an example of how to structure the feedback:

1. What was done well: Highlight something specific that the peer did well during the activity (e.g., clarity in explaining the angles, creativity in editing the video, etc.).
2. What can be improved: Suggest an area where the peer can improve (e.g., being more detailed in classifications, using more digital tools, etc.).
3. Next steps: Offer a suggested action to further enhance the peer's skills (e.g., practice more video editing, look for more examples of angles in real situations, etc.).
