Objectives
Duration: 10 - 15 minutes
This stage aims to establish the theoretical foundation and contextualize the theme of indirect ratio in students' daily lives. From this, it will be possible to direct practical activities, where students can apply the concepts learned in real and digital situations, promoting a more meaningful and engaging learning experience.
Main Objectives
1. Empower students to solve problems involving indirect ratio.
2. Understand the relationship between inversely proportional quantities.
Side Objectives
- Encourage the use of digital technologies as auxiliary tools in solving mathematical problems.
- Promote teamwork and collaboration among students.
Introduction
Duration: 10 - 15 minutes
The purpose of this stage is to immerse students in the context of the lesson, connecting the theme with real and everyday situations. This not only sparks their interest but also facilitates the understanding of the concepts that will be applied in practical activities. The use of digital technologies to search for information promotes engagement and student protagonism, as well as fostering collaboration and knowledge sharing.
Warming Up
🧠 Warm-up: Start the class by explaining that the indirect ratio is used when two quantities are inversely proportional, meaning that when one increases, the other decreases in the same proportion. Ask students to use their phones to find an interesting fact about the indirect ratio or situations in everyday life where this rule is applied. For example, they can look up how a vehicle's speed and travel time are inversely proportional. After a few minutes, invite some students to share what they found with the class.

2. 🚗 How can the indirect ratio be applied in practical situations, such as calculating speed and travel time?
3. 📈 Why is it important to understand the relationship between inversely proportional quantities in different areas of knowledge?
4. 🔧 How can digital tools assist us in solving problems involving indirect ratio?
5. 🧩 Did anyone find an interesting curiosity about the indirect ratio they would like to share?
Development
Duration: 70 - 75 minutes
The purpose of this stage is to provide students with a practical and contextualized experience of using the indirect ratio. The proposed activities aim not only to strengthen theoretical understanding but also to demonstrate the application of these concepts in modern and relevant scenarios, such as social media and sustainable economy. Moreover, the use of digital technologies facilitates student engagement and active participation, promoting collaboration and development of essential skills for the 21st century.
Activity Suggestions
It is recommended that only one of the suggested activities be carried out
Activity 1 - Digital Influencers and the Indirect Ratio 📸
> Duration: 60 - 70 minutes
- Objective: Apply the indirect ratio in a digital influencer scenario, reinforcing the understanding of inversely proportional quantities in a practical and contextualized way.
- Description: Students will simulate the life of digital influencers who need to calculate the time spent creating content depending on the number of followers and interactions each post generates. The activity involves creating posts on a fictitious platform and analyzing the results using the indirect ratio.
- Instructions:
-
Divide the students into groups of up to 5 people.
-
Each group should access an online platform, such as Canva or similar, to create fictitious content (posts) for a social network.
-
Students must set the following fictitious data before starting: number of followers, average time needed to create a post for a certain number of followers, and expected interactions.
-
Students must create a table relating the number of followers to the time required to create posts, considering that more followers require less time per post due to acquired experience.
-
The table should be used to create graphs and solve indirect ratio problems, such as predicting the creation time needed for different numbers of followers.
-
At the end, each group should share their results and conclusions with the class, explaining how they used the indirect ratio.
Activity 2 - The Circular Economy Game ♻️
> Duration: 60 - 70 minutes
- Objective: Encourage the practical application of the indirect ratio in an economic and sustainable context, promoting critical analysis and solving complex problems.
- Description: In this gamified activity, students will be challenged to solve indirect ratio problems in an economic scenario. They will simulate the functioning of a sustainable company that transforms waste into new products, calculating the time and resources needed according to the amount of waste available.
- Instructions:
-
Divide the students into groups of up to 5 people.
-
Each group should access a game or online simulation that allows the management of a small company (a Google Sheets simulation prepared by the teacher can be used).
-
Students should set the following fictitious data: initial amount of waste, time needed to transform waste into products, and the amount of final product.
-
Students should create a table relating the amount of waste to the time and resources needed, applying the indirect ratio to understand how the variation of one affects the other.
-
Using the table, the groups should solve problems based on possible situations, such as predicting production time for different quantities of waste or optimizing resources.
-
At the end, each group should present their results, explaining how the indirect ratio was applied and the optimization strategies found.
Activity 3 - Hacking Math with Social Networks 💻
> Duration: 60 - 70 minutes
- Objective: Integrate the indirect ratio into the analysis of social media data, promoting skills in data collection and interpretation and understanding of inversely proportional relationships.
- Description: Students will apply the indirect ratio in the context of a statistical campaign for social networks. They will learn to use digital tools to collect relevant data and solve problems of inverse relationships between engagement and reach of their posts.
- Instructions:
-
Divide the students into groups of up to 5 people.
-
Each group should access a social media tool (it could be a simulation or a real network with fictitious data) that allows them to analyze the engagement and reach of posts.
-
Students should define posts with different themes and characteristics, stipulating fictitious data for reach and engagement.
-
Groups should collect data and create a table correlating engagement with reach, using the indirect ratio to predict how engagement varies inversely with increased reach.
-
Using the table, the groups should solve practical problems, such as predicting the amount of engagement for different levels of reach or optimizing a campaign based on the results.
-
At the end, each group should present their findings and discussions, detailing the use of the indirect ratio in data analysis.
