Development

Duration: 70 - 80 minutes

The purpose of this stage is to provide students with an opportunity to apply and deepen their knowledge about rotations on the Cartesian plane, using digital tools and working collaboratively. The proposed activities aim to transform theoretical learning into practical and visually engaging experiences, connecting mathematical concepts to modern and relevant contexts.

Activity Suggestions

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

Activity 1 - Transforming Instagram into a Cartesian Plane

> Duration: 60 - 70 minutes

- Objective: Apply rotations on the Cartesian plane in a practical and visual manner, using social media to engage students.

- Description: In this activity, students will use their Instagram accounts to apply rotations on the Cartesian plane. They will create posts using geometric figures, which will be rotated 90º around the origin, and will post before and after the rotations.

- Instructions:

• Divide students into groups of up to 5 people.

• Each group will choose a simple geometric figure (triangle, square, or circle) and draw that figure in a drawing application (like Canva or similar).

• Students will post the original figure on Instagram along with the caption: 'Original Figure'.

• Using the drawing application, each group will rotate the figure 90º relative to the origin and create a new image.

• They will post the new image on Instagram with the caption: 'Figure Rotated by 90º'.

• Students should include a brief explanation in the posts about how the rotation was performed.

• Each group will present their posts to the rest of the class, explaining the rotation process and the changes observed.

Activity 2 - Gamification Adventure with Rotations

> Duration: 60 - 70 minutes

- Objective: Use gamification to reinforce knowledge about rotations on the Cartesian plane, promoting collaboration among students.

- Description: Students will participate in an RPG-style game where they will need to solve figure rotation challenges on the Cartesian plane to advance through levels. Using gamification software, each group will solve problems and record their answers on an online platform.

- Instructions:

• Divide students into groups of up to 5 people.

• Each group will use gamification software (like Kahoot or Google Forms) set up with challenges involving rotations on the Cartesian plane.

• The challenges will present geometric figures on a Cartesian plane that need to be rotated 90º around the origin.

• Each group discusses and solves the challenges together, recording their answers on the online platform.

• The challenges will include multiple-choice questions and text boxes for explanations.

• At the end of the challenges, each group will receive a report on their performance.

• Groups will discuss how they arrived at their answers and share their strategies with the class.

Activity 3 - Digital Influencers of Rotations

> Duration: 60 - 70 minutes

- Objective: Develop communication skills and the ability to explain mathematical concepts, using digital platforms for engagement and knowledge sharing.

- Description: Students will take on the role of digital influencers and create an explanatory video about rotations on the Cartesian plane, highlighting how these rotations are performed and their practical uses. The video will be published on a YouTube channel created by the class.

- Instructions:

• Divide students into groups of up to 5 people.

• Each group will discuss and script a video of up to 5 minutes explaining rotations on the Cartesian plane, focusing on 90º rotations.

• Students will use their phones to record the video, possibly using simple editing apps to enhance the presentation.

• The video should contain: an introduction about what rotation is, a practical example of rotation on the Cartesian plane, and an explanation of the importance of rotations in different contexts.

• Groups will publish their videos on a YouTube channel created by the teacher.

• Groups will watch each other's videos and provide constructive feedback.

• The teacher will guide a final discussion about the different approaches and the learning obtained through the activity.

Feedback

Duration: 20 - 25 minutes

The purpose of this stage is to provide a moment of collective reflection, where students can consolidate their learning, share experiences, and receive constructive feedback. This not only strengthens the understanding of the concepts addressed but also promotes communication, critical thinking, and collaboration skills among students.

Group Discussion

👥 Group Discussion: Promote a group discussion where each group has the opportunity to share what they learned during the activities, the challenges they faced, and the conclusions they reached. Suggested script to introduce the discussion:

1. Introduction: Explain the importance of reflecting on what was learned.
2. Sharing Experiences: Invite the groups to present their Instagram posts, gamification game results, and YouTube videos.
3. Learnings and Challenges: Ask what were the main learnings and the challenges faced during the activities.
4. Connections to Real Life: Encourage students to discuss how knowledge about rotations can be applied in real contexts, such as engineering, graphic design, and programming.

Reflections

1. 🧐 Reflection Questions:

1. What was the most challenging part of performing rotations on the Cartesian plane?
2. How did digital tools help in understanding the concept of rotation better?
3. In what ways can we apply knowledge about rotations in other subjects or everyday situations?

360° Feedback

🔄 360° Feedback: Instruct students to perform a 360° feedback step within their groups. Guidelines for feedback:

1. Constructive and Respectful: Emphasize the importance of feedback being constructive and given respectfully.
2. Positive Aspects: Ask each student to highlight positive aspects of their peers' work.
3. Areas for Improvement: Suggest that they point out areas where they believe the group can improve, always in a kind and constructive manner.
4. Personal Learnings: Encourage each student to reflect on what they learned from their peers' contributions.

Conclusion

Duration: 10 - 15 minutes

🎯 Purpose: The purpose of this stage is to consolidate learning, reinforcing the connection between theoretical concepts and their practical, modern applications. This moment of reflection and final analysis helps students internalize the concepts of rotation, understanding their importance and utility, in addition to strengthening the understanding of the activities carried out during the lesson. 💪
