The purpose of this stage is to engage students with the topic through a quick digital research that connects the concept of factorial to its practical and interesting use. This interactive start aims to capture students' attention and stimulate them to actively participate in the lesson.

Warming Up

Warm-up: Start the lesson with a brief explanation of the concept of factorial. For example: 'The factorial of a number is the product of all positive integers less than or equal to that number. It is represented by the symbol '!'.' Then, ask students to use their phones to find an interesting fact about factorial, such as its application in combinatorics, probability, or even its presence in programming algorithms.

Initial Reflections

1. What is a factorial and how is it represented?

2. What is the importance of factorial in mathematics?

3. Did you discover any interesting use of factorial during your research on your phones?

4. Can anyone calculate the factorial of a simple number, like 4!, without using a calculator?

5. How can we apply factorials in real-world problems?

Development

Duration: 70 - 85 minutes

The purpose of this stage of the lesson plan is to allow students to apply the acquired knowledge in a practical and interactive way. By utilizing technology and gamification, students become protagonists of their learning, developing skills such as creativity, collaboration, and critical thinking while solidifying their understanding of factorials.

Activity Suggestions

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

Activity 1 - Math Influencer 📱

> Duration: 60 - 70 minutes

- Objective: Allow students to use communication and creativity skills to explain mathematical concepts, promoting a deeper understanding through active teaching.

- Description: Students will become digital influencers, creating content for social media that explains the concept of factorial in a playful and attractive way. Each group should create a video of up to 2 minutes and publish it on a social media platform or in a virtual learning environment of the school.

- Instructions:

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

• Ask each group to choose a popular social media platform among them (YouTube, Instagram, TikTok, etc.).

• Request that students create a short script explaining the concept of factorial and its applications. The video can include practical examples and curiosities.

• Students should use their phones to record the video. Encourage them to be creative, using editing elements such as visual effects and soundtracks.

• Each group must edit the video and publish it on the chosen network or in a virtual learning environment provided by the teacher.

• After publishing, each group should present their video to their peers, explaining the creative process and the key points addressed.

Activity 2 - Digital Escape Room 🔐

> Duration: 60 - 70 minutes

- Objective: Encourage collaboration, critical thinking, and practical application of factorial concepts in a playful and engaging environment.

- Description: Students will participate in an escape room-style challenge, where they will need to solve mathematical puzzles related to factorials to advance to the next stage. This challenge will be conducted through a specific online platform for educational games.

- Instructions:

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

• Access an online platform for educational escape rooms, such as Breakout EDU or a similar tool.

• Instruct students to navigate through different virtual 'rooms' solving puzzles that involve factorial calculations and their properties.

• Each puzzle solved will provide a clue for the next stage. Students must cooperate and communicate effectively to solve each challenge.

• After completing the challenge, each group should discuss the solutions and the logic behind the answers, presenting to the rest of the class how they overcame each step.

Activity 3 - Gamification: Factorial Adventure 🎮

> Duration: 60 - 70 minutes

- Objective: Utilize gamification to make learning mathematical concepts more engaging and interactive, encouraging practical application and creativity.

- Description: Students will create a simple digital game using online game creation tools (such as Scratch or Tynker). The game should be based on challenges involving the calculation of factorials and their properties.

- Instructions:

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

• Each group should choose an online game creation tool and familiarize themselves with it.

• Students should design a storyboard for their game, detailing each level and the mathematical challenges that players must overcome.

• Encourage groups to be creative by incorporating interesting characters, scenarios, and soundtracks.

• Groups must develop the digital game and test it among themselves to ensure that the challenges are appropriate and fun.

• Each group will present their game to the class, explaining the mathematical concepts that players need to apply to advance through the levels.

Feedback

Group Discussion

Group Discussion 🗣️

Facilitate a group discussion with all students, where groups share what they learned by participating in the activities and their conclusions. Use the following script to introduce the discussion:

1. Introduction: "Let's share what each group learned by performing the proposed activities today. Each group will have five minutes to explain what they did and the conclusions they reached."
2. Group Presentations: "Each group will present their work, starting with a summary of the factorial concept they explored and how they applied it in the activity."
3. Debate and Questions: "After each presentation, we will open the discussion for questions and comments from peers."
4. Conclusion: "To finish, each group will share one key lesson or insight they took away from the activity."

Reflections

1. How did creating the videos or games help you better understand the concepts of factorial? 2. What challenges did you encounter during the activities and how were they overcome? 3. How did teamwork and collaboration influence the final outcome?

360° Feedback

360° Feedback 🔄

Instruct students to perform a 360° feedback stage, where each student should receive feedback from other students in the group they worked with during the activity. Guide the class to ensure that feedback is constructive and respectful, using the following structure:

1. Positive Points: Each student should highlight at least one positive point about a peer, mentioning something specific that they did well during the activity.
2. Areas for Improvement: Suggest an area where the peer could improve, always in a constructive and respectful manner.
3. Practical Suggestions: Offer a practical suggestion on how the peer can improve that area.

Conclusion

Duration: 10 - 15 minutes
