- Description: In this activity, students will create a series of Instagram posts as 'math influencers', explaining the concepts of a parallelogram and demonstrating how to calculate the measures of sides and angles. They should use images, short videos, and stories to make the content more engaging and accessible.

- Instructions:

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

• Each group must create a fictitious Instagram account (or private if they prefer to use personal accounts).

• The groups must plan a series of posts to explain the concepts of parallelogram, including feed posts and stories:

• Introduction Post: An image or short video explaining what a parallelogram is.

• Educational Post: A carousel of images or slides explaining how to calculate the measures of the sides and angles of a parallelogram.

• Practical Application Post: Images or videos showing examples of parallelograms in real life and how these calculations are applied.

• Interaction with Followers: Create polls or quizzes in the stories to test the knowledge of the 'followers'.

• The groups must present the posts to the class, explaining the visual and educational choices they made.

Activity 2 - Geometric Treasure Hunt ️‍♂️

> Duration: 60 - 70 minutes

- Objective: Engage students in a physical and interactive activity that reinforces the concepts of parallelograms through practical challenges and problem-solving.

- Description: Students will participate in a 'Geometric Treasure Hunt' using QR codes scattered throughout the classroom or school. Each QR code will lead students to math challenges involving parallelograms that must be solved to find clues and advance to the next code.

- Instructions:

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

• Create and spread QR codes around the classroom or school, each containing a question or challenge related to parallelograms.

• The challenges can include calculating angles, perimeters, areas, and identifying parallelograms in complex figures.

• Groups must solve the challenges to obtain clues that will lead them to the next QR code.

• Each group must record their answers and explain how they arrived at them.

• In the end, the groups should present a brief summary of the solutions found and reflect on what they learned.

Activity 3 - Gamification: Parallelogram Quest 

> Duration: 60 - 70 minutes

- Objective: Utilize gamification to make learning the concepts of parallelogram fun and competitive, encouraging collaboration and critical thinking.

- Description: Students will participate in a digital game called 'Parallelogram Quest', where they will be challenged to solve problems and complete missions related to parallelograms. Using a gamification platform, each group can progress in the game as they get answers right and score points.

- Instructions:

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

• Using a gamification platform like Kahoot, Quizizz, or Google Forms, set up a series of questions and missions involving parallelograms.

• Each correct challenge will yield points and unlock the next mission.

• Groups must collaborate to solve the questions and progress in the game.

• Challenges can include everything from measuring calculations to identifying parallelograms in complex shapes or practical applications.

• At the end, the group with the most points may receive a 'virtual medal' or certificate of completion.

Feedback

Duration: 15 - 20 minutes

 Purpose: This stage aims to provide a moment of reflection and consolidation of learning. Through group discussion and 360° feedback, students have the opportunity to review the concepts worked on, share experiences, and learn from each other. In addition, the practice of constructive feedback encourages self-criticism and personal development in a collaborative environment.

Group Discussion

✍️ Group Discussion: Promote a circle discussion with all students, where each group should briefly present what they learned during the activities. Use the following script to introduce the discussion:

Introduction: 'Let's start a discussion to share what we learned today about parallelograms. Each group will have the opportunity to talk about their experience, the challenges they faced, and the solutions they found.' Sharing Learnings: 'I would like each group to start by talking about a specific aspect of the parallelogram that they found most interesting or challenging.' Discussion of Practical Applications: 'Can anyone share how the concepts we learned today can be applied in the real world or in future careers?'

Reflections

1.  Reflection Questions: What did you find most challenging about today's activities and why? 2. How did group collaboration facilitate or hinder your understanding of the concepts of parallelograms? 3. How did the use of digital tools help you better understand the content?

360° Feedback

 360° Feedback: Instruct students to conduct a 360° feedback stage where each student should receive feedback from their group members about their participation and contribution in the activities. Guide the class to ensure that the feedback is constructive and respectful, using the 'S.B.I.' technique (Situation, Behavior, Impact). For example:

Situation: Describe a specific situation where the student demonstrated noticeable behavior. Behavior: Explain the observed behavior. Impact: Describe the impact of this behavior on the group or activity.

Encourage students to give positive feedback and improvement suggestions in a way that helps their peers grow.
