- Instructions:

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

• Each group must choose a social media platform for which they will create the content.

• List the components of the triangle that must be explained in the video: vertices, sides, and angles.

• Classify the triangles based on their sides (scalene, isosceles, and equilateral) and angles (acute, right, and obtuse).

• Students should create a creative script for the video, which may include skits, cartoons, fake interviews, or any other format they find interesting.

• Record the video using their cell phones and edit it using available tools, such as iMovie, InShot, or any other free video editing app.

• Share the video on the chosen platform and, if allowed, on school channels, encouraging interaction from other students and teachers.

• Each group must present the video to the class, explaining their script choices and how they approached the explanation of mathematical concepts.

Activity 2 - Triangular Challenge: Virtual Escape Room 🗝️

> Duration: 60 - 70 minutes

- Objective: Promote teamwork, problem-solving skills, and the creative use of digital technologies to learn about triangles in a fun way.

- Description: Students will participate in a virtual escape room where they will solve puzzles and mathematical problems related to triangles to 'escape' the room. Using platforms like Google Forms or gamification tools, they will work in groups to solve each stage based on triangle concepts.

- Instructions:

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

• Explain that they will participate in a virtual escape room, where they will need to use their cell phones or computers to solve puzzles related to triangles.

• Each group will receive a link to a Google Form or an online escape room platform set up with a series of challenges.

• The puzzles will include identifying the components of the triangle, classifying triangles based on their sides and angles, and solving applied problems.

• Students must work together to find the correct answers that will unlock the next clue or challenge.

• The first group to complete all challenges and 'escape' the room will be declared the winner.

• At the end, lead a discussion about the strategies used and difficulties encountered, reinforcing the concepts learned.

Activity 3 - Adventure in the World of Triangles 🌍

> Duration: 60 - 70 minutes

- Objective: Foster research, analysis skills, and the use of digital tools to identify and understand triangles in the context of the real world.

- Description: Students will create an interactive map using Google My Maps or a similar tool, where they will identify and classify triangles found in images of maps and famous monuments around the world. They can add notes and descriptions explaining each triangle and its characteristics.

- Instructions:

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

• Explain that they will create an interactive map, identifying and classifying triangles in images of maps and famous monuments.

• Provide examples of places and monuments where triangles can be found, such as the Eiffel Tower, pyramids, etc.

• Each group must use tools like Google My Maps, adding markers at locations where they identify triangles.

• Students must identify the vertices, sides, and angles in each triangle and classify them based on their sides and angles.

• Add notes and descriptions in each marker, explaining the characteristics of the identified triangles.

• The groups must share their interactive maps with the class and present their findings, explaining the associated mathematical concepts.

• Encourage students to discuss how triangles are used in architecture and engineering, connecting learning with the real world.

Feedback

Duration: 20 - 25 minutes

The purpose of this stage is to consolidate learning through reflection and the exchange of experiences, promoting an environment of collaboration and mutual respect. The group discussion allows students to share and confront their ideas, while the 360° feedback offers an opportunity for personal growth and the development of social and communication skills.

Group Discussion

Facilitate a group discussion where each group will have the opportunity to present their conclusions and experiences during the activities. Follow this outline to introduce the discussion:

3. Debate: Encourage students to ask questions to the presenting groups and discuss different approaches and discoveries.
4. Conclusion: Summarize the main points discussed, highlighting how technology helped deepen the understanding of the mathematical concepts related to triangles.

Reflections

1. What were the main challenges you and your group faced while carrying out the activities? How did you overcome them? 2. How did technology help facilitate or enrich your learning about triangles? 3. Do you see any practical application of the triangle concepts you learned today in your daily life or in other areas of knowledge?

360° Feedback

For the 360° feedback stage, instruct the students to provide constructive and respectful feedback to their group members. They can use the following format:

1. Positive Aspects: Each student should highlight something positive they observed in their peer during the activity, such as collaboration, creativity, or leadership.
