Warming Up

To start the lesson on the Decimal System and make the topic more relevant to students, ask them to use their cell phones to find an interesting fact about the decimal numbering system. Encourage them to look for information from reliable sources and share these facts with the class. For example, they might discover when and where the decimal system was created or how it is used in different parts of the world today.

Initial Reflections

1. Why is the decimal system called 'decimal'?

2. How are numbers positioned and what does the position of each digit mean?

3. Can you give a practical example of where we use the decimal system in our daily lives?

4. What is the difference between whole numbers and decimal numbers?

5. What are the advantages of using the decimal system compared to other numbering systems?

Development

Duration: 75 to 85 minutes

The purpose of this stage is to provide students the opportunity to apply their knowledge of the Decimal System in practical and contemporary contexts. Creative and digital activities engage students, promoting deeper understanding, collaboration, and the development of additional skills such as communication, design, and problem-solving.

Activity Suggestions

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

Activity 1 - Influencer Challenge: Understanding Decimal Numbers! 🌟

> Duration: 60 to 70 minutes

- Objective: Develop students' communication and creativity skills while explaining mathematical concepts, and promote a deep understanding of the Decimal System through a contemporary and digital approach.

- Description: Students will become digital influencers and create short videos explaining fundamental concepts of the Decimal System. The goal is to make learning dynamic and interactive. They should use video editing apps on their phones to include visual effects that make the concepts easier to understand.

- Instructions:

• Divide the class into groups of no more than 5 students.

• Each group must choose a concept related to the Decimal System (for example, positional value, reading and writing decimal numbers, etc.).

• Students should create a script for a 2-3 minute video, explaining the chosen concept in a creative and engaging way.

• Use video editing apps or social media like TikTok to record and edit the video. Encourage the use of graphics, music, and other digital resources.

• After creating the videos, groups should share the content with the class via a link or by displaying it on the classroom screen.

• Allocate time for discussions and feedback on the presented videos.

Activity 2 - Digital Treasure Hunt: Find the Digital Treasure 🕵️‍♂️💡

> Duration: 60 to 70 minutes

- Objective: Promote collaboration and active learning through a gamified activity that reinforces the concepts of the Decimal System in a fun and engaging way.

- Description: Students will participate in a digital treasure hunt where they need to solve mathematical challenges related to the Decimal System to advance through stages and find the 'treasure'. Each challenge will include problems that require reading, writing, and understanding decimal numbers.

- Instructions:

• Create an online document (Google Docs, for example) with a series of clues and mathematical challenges related to the Decimal System.

• Divide the class into groups of no more than 5 students.

• Each group must access the document, follow the clues, and solve the challenges to advance to the next stage.

• Groups can use cell phones and computers to research, calculate, and discuss the answers.

• Encourage cooperation and division of tasks within the groups.

• The first group to find the 'treasure' (solving all the challenges) wins, but all must present their solutions and reasoning.

Activity 3 - App Designers: Building a Decimal Numbers App 📱🚀

> Duration: 60 to 70 minutes

- Objective: Stimulate students' creativity and critical thinking as they plan and design a digital educational tool, consolidating their understanding of the Decimal System in an innovative way.

- Description: Students will act as app designers and create a prototype of an educational app that teaches other students about the Decimal System. Using tools like Figma or Canva, they must plan the layout, content, and functionalities of the app.

- Instructions:

• Divide the class into groups of no more than 5 students.

• Each group should discuss and plan the functionalities and content of an app that teaches the Decimal System.

• Use tools like Figma or Canva to create prototypes of the app's screens.

• Students must think about the design (colors, fonts, icons) and interactions (how the user will navigate the app).

• Each group presents its prototype to the class and explains how the app works and how it teaches about the Decimal System.

• During the presentations, encourage questions and suggestions for improvements from classmates.

Feedback

Duration: 20 to 25 minutes

The purpose of this stage is to provide an opportunity for students to reflect on what they learned, discuss their experiences, and receive constructive feedback from peers. This stage reinforces the collaborative and individual understanding of the concepts worked on, as well as developing communication skills, self-criticism, and mutual respect.

Group Discussion

Facilitate a group discussion with all students where groups share what they learned from the activities and their conclusions. To introduce this discussion, use the following script: Start by asking students what surprised them most during the activities. Ask each group to share their main discoveries and difficulties they faced. Encourage reflection on how the activities helped them better understand the Decimal System. Ask students how digital tools and group collaboration contributed to their learning.

Reflections

1. What was the most challenging concept of the Decimal System and how did you overcome that difficulty? 2. How did the digital activities help you understand decimal numbers better? 3. What did you learn about the importance of collaboration and teamwork during these activities?

360° Feedback

Instruct students to carry out a 360° feedback step, where each student should receive feedback from other students in the group they worked with on the activity. Explain that the feedback should be constructive and respectful. Guide the class to follow these guidelines: Praise positive aspects such as creativity, collaboration, and understanding of the concept. Suggest improvements gently and specifically, focusing on aspects that can be enhanced. Self-critique by mentioning what each believes they could have done better.

Conclusion

Duration: 10 to 15 minutes

🎯 Purpose 🎯
