Activity Suggestions

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

Activity 1 - Digital Influencers of the Rectangle 

> Duration: 60 - 70 minutes

- Objective: Teach the calculation of the rectangle's area in a playful and contextualized manner, using social media to engage students and promote collaboration.

- Description: In this activity, students will split into small groups and create a series of Instagram posts explaining, in a creative and engaging way, how to calculate the area of a rectangle. They will use images, short videos, and texts to teach the concept, linking it to everyday situations, such as renovating a room or planning a garden.

- Instructions:

• Form groups of up to 5 students.

• Each group must create an Instagram profile dedicated to the theme 'Area of the Rectangle'.

• Students must create at least 3 posts: one with the basic formula (A = base x height), one showing a practical example (like calculating the area of a rectangular floor), and one final post with a more complex application (like calculating the area of a construction plot).

• Use images and videos to make the posts more dynamic and eye-catching.

• Groups must interact with each other's posts, asking questions and making comments to promote discussion and engagement.

• Each group presents their posts to the class and explains the logic behind each one.

Activity 2 - Gamification: The Rectangle Master Mission 

> Duration: 60 - 70 minutes

- Objective: Apply the calculation of the rectangle's area in a series of practical situations, reinforcing learning through gamification to make the experience fun and interactive.

- Description: Students will be divided into groups and must solve a series of challenges in a digital game that involves calculating the area of different rectangles. The game, developed on a platform like Kahoot or Quizizz, should include problems applied to everyday situations, such as interior decoration or gardening.

- Instructions:

• Form groups of up to 5 students.

• Each group will receive a link to access the game developed on the chosen platform.

• The challenges range from the basic application of the formula A = base x height to more complex problems that require multi-step solutions.

• Students must work together to solve the problems and enter their answers in the game.

• At the end of the game, each group will see their score and help the class discuss the solutions and mistakes made.

Activity 3 - YouTube Project: Math Vloggers 

> Duration: 60 - 70 minutes

- Objective: Develop communication skills and apply the calculation of the rectangle's area in practical situations, using video production and editing as learning tools.

- Description: In this activity, students will use their phones to record explanatory videos about calculating the area of a rectangle. They must create a fictional scenario where they need to apply the concept, such as a problem encountered in a renovation or landscape design project. The videos will later be edited and presented to the class.

- Instructions:

• Form groups of up to 5 students.

• Each group must plan a script that involves a practical situation requiring the calculation of the rectangle's area.

• Record short videos (2 to 5 minutes) explaining the application of the concept in the chosen situation.

• Students should use video editing apps to make the content more interesting. Suggest using captions, background music, and visual effects.

• Present the videos in class and discuss the different approaches and solutions presented by the groups.

Feedback

Duration: 20 - 25 minutes

The purpose of this stage of the lesson plan is to provide a moment of reflection and consolidation of the knowledge acquired. By sharing and discussing the results of the activities, students have the opportunity to learn from their peers' experiences. The 360° feedback promotes communication and collaboration skills, helping each student recognize their strengths and areas for improvement.

Group Discussion

Promote a group discussion where each group shares what they learned and their conclusions about the activity performed. Suggest the following outline to introduce the discussion: Start by asking each group to present their Instagram posts, the results of the digital game, or the YouTube videos, depending on the activity performed. Ask them to explain the logic behind their solutions and how they arrived at them. Encourage the class to ask questions and comment on the groups. Lead the discussion by highlighting the different methods used to calculate the area of the rectangle and the importance of applying these concepts in practical everyday situations.

Reflections

1. What were the main challenges faced during the activities? 2. How did the use of social media, gamification tools, or video creation help in learning the calculation of the rectangle's area? 3. In what ways do you think you could apply what you learned in everyday or future situations?

360° Feedback

Conduct a 360° feedback session where each student will receive feedback from their group members. Guide students to provide constructive and respectful feedback, highlighting strengths and areas for improvement. Use supportive phrases like: 'I liked how you...', 'You did a great job on...', 'You could improve on...'. Emphasize the importance of being specific and positive to help each student's individual development.

Conclusion

Duration: 10 - 15 minutes

Purpose of the Conclusion : The purpose of this stage is to consolidate and reflect on the knowledge acquired throughout the lesson.
