Activity Suggestions

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

Activity 1 - Mathematics Circus - Influencers in Action 🎪📲

> Duration: 60 - 70 minutes

- Objective: Apply mathematical concepts of circles using modern digital tools and develop communication and teamwork skills.

- Description: Students will create a short video, in the style of TikTok or Instagram Reels, explaining concepts of circles and solving a related problem. They should use graphics, animations, and any digital tool they find suitable to make the video attractive and educational.

- Instructions:

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

• Each group should choose a characteristic of the circle (arcs, chords, or inscribed angles) and a problem to solve.

• Students must create a script for the video explaining the chosen concept and the solution to the problem.

• Use apps like Canva, InShot, or any other video editor to create visuals and animations.

• Record and edit the video, ensuring the explanation is clear and correct.

• In the end, each group should publish the video on a platform of their choice and share the link in the classroom.

• The videos will be displayed and discussed with the entire class, highlighting strengths and possible improvements.

Activity 2 - Geometric Treasure Hunt! 🗺️🔍

> Duration: 60 - 70 minutes

- Objective: Engage students in an interactive and collaborative activity, applying concepts of circles to solve problems in a playful context.

- Description: Students will participate in a digital 'treasure hunt' where they will have to solve a series of problems involving circles to find clues and move to the final location of the 'treasure'. The clues will be provided via QR codes scattered throughout the classroom or school.

- Instructions:

• Prepare QR codes containing mathematical problems about circles and spread them throughout the classroom or school.

• Divide students into groups of up to 5 people.

• Each group must scan the QR codes to access the problems.

• Solve each problem to get the location of the next clue.

• The clues must be solved in sequence until arriving at the final 'treasure'.

• Use QR code reader apps and document sharing platforms to deliver and verify the answers.

• The final treasure can be a symbolic prize or additional points in the assessment.

Activity 3 - Angle Journey - Game On! 🎮📐

> Duration: 60 - 70 minutes

- Objective: Use gamification to reinforce the learning of circle concepts, promoting a healthy competitive and collaborative environment.

- Description: Students will participate in an educational online game where each phase represents a challenge involving circles. The goal is to overcome all phases to complete the 'Angle Journey' and become a master of the studied mathematical concepts.

- Instructions:

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

• Each group must access an educational gaming platform, such as Kahoot! or Quizizz, where the challenges have been pre-configured.

• Each phase of the game represents a different problem about circles (arcs, chords, inscribed angles, etc.).

• Students must work as a team to solve the problems and advance in the game.

• Monitor the progress of the groups and provide tips and assistance as needed.

• At the end of the allotted time, discuss the results and reinforce the concepts covered.

Feedback

Duration: (20 - 25 minutes)

The purpose of this stage is to consolidate learning through reflection and exchange of experiences among students. Group discussion and 360° feedback encourage self-evaluation and collaboration, allowing students to identify points for improvement and reinforce concepts, as well as develop social and communication skills.

Group Discussion

Promote a group discussion with all students. Follow this script to introduce the discussion:

Introduction: Ask the students how they felt carrying out the activities and what their first impressions were. Exposition: Ask each group to present their main discoveries and difficulties faced, highlighting which digital tools they used and how they contributed to the understanding of the concepts. Comparison: Provide a moment for groups to compare their experiences, discussing similarities and differences in methods and results. Conclusion: Encourage students to reflect on the impact of practical activities on their understanding of concepts and how they can apply this knowledge in other situations.

Reflections

1. How did the use of digital tools influence your understanding of the concepts of circles? 2. What were the main challenges you faced during the activities and how did you overcome them? 3. How did group activities help in the development of your knowledge about circles?

360° Feedback

Conduct a 360° feedback stage, where each student should receive feedback from other group members. Guide the class to ensure that the feedback is constructive and respectful, addressing positive points and areas for improvement. Use the following guidelines for feedback:

Specific and Objective: The feedback should address specific situations or behaviors observed during the activity. Constructive: Highlight strengths and suggest improvements positively. Respectful: Maintain a respectful and empathetic tone, avoiding personal criticism.

Conclusion

Duration: (10 - 15 minutes)

💡 Purpose: This final stage serves to consolidate learning and reinforce the connection between mathematical concepts and their practical applications. It is an opportunity to reflect on what has been learned and how these skills can be used in other areas of life and future careers.
