Activity Suggestions

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

Activity 1 - 🎮 Adventure on the Number Line

> Duration: 60 to 70 minutes

- Objective: Develop understanding of natural numbers and their placement on the number line through a fun and interactive activity, using digital technology.

- Description: In this activity, students will become characters in a digital adventure. They will have to complete a series of mathematical challenges in an online game that uses the number line as the basis for the missions. The goal is to help the main character cross a magical world, overcoming obstacles that require the correct placement of natural numbers on the line.

- Instructions:

• Divide the students into groups of up to 5 people and ask each group to access the online game 'Adventure on the Number Line' on their phones or computers.

• Each group will register in the game and choose an avatar to represent their group.

• Explain that the goal of the game is to complete the missions using the number line to correctly position the natural numbers.

• Each mission will involve a mathematical challenge, such as arranging numbers in ascending order, identifying gaps on the number line, or solving addition/subtraction problems using the line.

• As the students play, circulate around the room to provide support and ensure everyone understands the instructions and is participating actively.

• At the end of the game, ask each group to share their main strategies and difficulties.

Activity 2 - 📱 Instagram of Natural Numbers

> Duration: 60 to 70 minutes

- Objective: Encourage students' creativity while developing understanding of natural numbers and their location on the number line using a fictional social media platform.

- Description: Students will create a fictional Instagram profile for a 'natural number influencer'. Each group will choose a natural number to represent and create posts, stories, and interactions with other 'influencer numbers' in the class. The posts must highlight the position of the number on the number line and its relationship with other numbers.

- Instructions:

• Divide the students into groups of up to 5 people and suggest they choose a natural number that will be the group's 'influencer'.

• Each group must create a fictional profile for their number using Canva or another graphic design app, simulating an Instagram profile.

• Guide the students to create posts and stories about the number, including its position on the number line, curiosities, and interactions with other numbers (collaborative posts).

• Ask them to publish their designs in a shared cloud folder (Google Drive or similar) so that everyone can see and comment.

• At the end, open a space for each group to present their profile and explain how their number relates to other natural numbers on the line.

Activity 3 - 🔢 Mathematical TikTok: Number Line Challenges

> Duration: 60 to 70 minutes

- Objective: Promote understanding of natural numbers and the number line through digital content creation, stimulating collaboration and communication among students.

- Description: Students will create short videos on TikTok explaining concepts related to natural numbers and the number line. Each group will develop and record a mathematical challenge, which other groups will have to solve and respond to in the comments.

- Instructions:

• Divide the students into groups of up to 5 people and guide each group to create a script for a short TikTok video about a topic related to the number line and natural numbers.

• The scripts must include a clear explanation of the concept, an example, and a challenge for other groups to solve.

• Students will use their phones to record and edit the videos, using TikTok filters and effects to make the content more engaging.

• Ask the groups to post their challenges on a secure video sharing platform, such as Google Drive or Flipgrid.

• Groups will watch each other's videos and respond to the challenges in the comments, explaining how they came to their solutions.

• At the end, have a discussion about the different challenges presented and how each group solved the problems.

Feedback

Duration: 15 to 20 minutes

The aim of this stage of the lesson plan is to provide a moment of reflection and evaluation about the activities performed, promoting collaborative learning and the development of communication and constructive criticism skills. This also allows the teacher to identify strengths and areas that need more work.

Group Discussion

🗣️ Group Discussion: Conduct a group discussion with all students where groups share what they learned while performing the activities and their main conclusions. A suggested script to introduce this discussion could be: 'Let's now share each group's experiences. I would like each group to talk a little about their activity, the challenges they encountered, and the solutions they developed. How was the interaction with digital technologies? What did you learn about the number line and natural numbers?'

Reflections

1. 📌 Reflection Questions: 1. What was the most challenging part of the activity and why? 2. How did the use of digital tools help you better understand the concept of the number line? 3. How did group activities contribute to each one's learning?

360° Feedback

🔄 360° Feedback: Instruct students to conduct a 360° feedback phase, where each student must receive feedback from other group members. Guide the class to ensure that feedback is constructive and respectful, using phrases like 'I liked when you...' and 'It would be interesting if you could...'. Explain the importance of giving and receiving feedback for personal and academic growth.

Conclusion

Duration: 10 to 15 minutes

💡 Aim: The aim of this stage is to conclude the class reflectively and amusingly, reinforcing the explored content in a light and current manner, and showing its practical relevance in daily life. This incorporates learning into a broader context, connecting it to students' daily experiences.
