Then, ask students to use their phones to research and share an interesting fact about angles that they find online. This initial activity should engage them and spark curiosity about the topic.

Initial Reflections

1. What is an angle and where can we find them in our daily lives?

2. What are the main types of angles that you know?

3. What is a protractor used for and how is it utilized to measure angles?

4. Do you think measuring angles is important? Why?

5. Did anyone find an interesting fact about angles that they would like to share with the class?

Development

Duration: 60 - 70 minutes

The purpose of this stage is to allow students to apply the knowledge acquired about angles in practical and contextualized situations, using digital tools to enhance learning. The proposed activities not only reinforce theoretical content but also promote skills such as teamwork, creativity, and the use of modern technologies.

Activity Suggestions

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

Activity 1 - Angle Influencers 

> Duration: 60 - 70 minutes

- Objective: Apply knowledge about angles in real contexts using communication skills and digital tools.

- Description: Students become digital influencers and create content for social media about the importance of angles in daily life.

- Instructions:

• Divide the students into groups of up to 5 people.

• Each group must choose a specific theme where angles are relevant (e.g., architecture, photography, sports).

• Students must create a short video (1-2 minutes) simulating a digital influencer explaining the importance of angles in the chosen theme.

• Use phones to record the videos and basic editing apps to give a final touch.

• The videos should be posted on a platform chosen by the school (e.g., YouTube, Instagram) and shared with the class.

• Host a screening session where each group presents their video and briefly explains it.

Activity 2 - Angle Hunt 

> Duration: 60 - 70 minutes

- Objective: Identify and measure angles in everyday situations using digital tools.

- Description: A gamified activity where students search for angles around the school environment, photographing and measuring them with phone apps.

- Instructions:

• Divide the students into groups of up to 5 people.

• Provide a list of specific angles that students should find (e.g., right angle, acute angle, obtuse angle).

• Students should use their phones to take pictures of objects or structures that have the listed angles.

• Use an angle measurement app to measure the angles in the taken photos.

• Each group creates a small digital album with the photos and measurements made, using an online presentation tool.

• Wrap up the activity with a presentation of the digital albums, where each group explains the angles found and their measurements.

Activity 3 - Virtual Architects ️

> Duration: 60 - 70 minutes

- Objective: Apply concepts of angles in the creation of architectural projects using digital technologies.

- Description: Students take on the role of architects and use 3D modeling software to create a structure, applying knowledge about angles.

- Instructions:

• Divide the students into groups of up to 5 people.

• Each group should use a free 3D modeling software (e.g., SketchUp) to create a simple project that includes different types of angles.

• The projects should be based on a theme chosen by the group (e.g., a park, a monument, a house).

• Students should measure and document the angles included in their project.

• Host a presentation session where each group explains their project and highlights the angles used.

• The projects can be shared on an online platform for all students to view and comment.

Feedback

Duration: 15 - 20 minutes

The purpose of this stage is to foster collective reflection on the learned material, promote the exchange of knowledge and experiences among students, and strengthen communication and critical skills through constructive feedback. Additionally, this stage aims to consolidate the content of angles, connecting it to real contexts and the use of digital tools.

Group Discussion

Promote a group discussion with all students, where each group will have the opportunity to share their discoveries and conclusions. Use the following script to introduce the discussion:

1. Introduction: Ask each group to present a summary of the activity carried out, highlighting the main learnings and challenges faced.
2. Connection to Daily Life: Ask the students how the angles found and measured are present in their daily lives and in what other situations they think this knowledge could be useful.
3. Comparison of Results: Encourage groups to compare their measurements and analyses, discussing similarities and differences and what might have caused these variations.

Finish the discussion by addressing the importance of measuring angles in various fields and professions, highlighting the interdisciplinary aspects of mathematical knowledge.

Reflections

1. How did the use of digital tools facilitate angle measurement? 2. What was most challenging in the angle identification and measurement activity? 3. How could you apply the knowledge about angles in other subjects or everyday situations?

360° Feedback

Conduct a 360° feedback session. Instruct students to reflect on teamwork, highlighting positive aspects and areas for improvement for each colleague. Guide the class to follow these guidelines for constructive and respectful feedback:

1. Be Specific: Provide concrete examples of what the colleague did well and what could improve.
2. Be Respectful: Use a positive and respectful tone, even when pointing out areas for improvement.
3. Balance: Offer both positive feedback and suggestions for improvement.

Ask each student to write a brief comment for each group member, which will be shared after being reviewed by the teacher. Conclude the activity by emphasizing the importance of constructive feedback for personal and professional growth.

Conclusion

Duration: 10 - 15 minutes

 Purpose: This stage aims to summarize in a fun and concise way the main content covered, connecting the topic to the modern world and its dynamics.
