3. Apply data interpretation to real-life situations: Students should be able to apply the knowledge acquired about data interpretation to everyday problems, relating theory to practice.

Secondary objectives

1. Stimulate critical thinking: In addition to understanding and applying data interpretation, students should be encouraged to question the information presented in graphs and charts, thus developing more critical and analytical thinking.

2. Promote teamwork: Through group activities, students should learn to work together, sharing ideas and solving problems cooperatively. This secondary objective will contribute to the development of important social skills.

Introduction (10-15 minutes)

1. Review of previous concepts: The teacher should begin the class by reviewing basic mathematical concepts that are fundamental to understanding the topic of the class. This includes concepts of coordinate axes, types of graphs (such as bars, lines, pie charts), and how to read and interpret information in tables. This review can be done interactively, asking students to share what they already know about the subject and encouraging brief discussions. (3-5 minutes)

2. Problem situations: To arouse students' interest in the topic, the teacher can present two problem situations. The first could be the analysis of a company's sales graph over a year, where students must identify the months of highest and lowest sales, as well as growth or decline trends. The second situation could be reading a table of results from a sports championship, where students must identify which teams performed best. (3-5 minutes)

3. Contextualization: The teacher should then introduce the concept of data interpretation and explain how it is used in various areas of knowledge, such as economics, meteorology, health, among others. It should be emphasized the importance of knowing how to interpret data correctly and critically, to avoid erroneous or biased conclusions. (2-3 minutes)

4. Getting students' attention: To make the introduction more interesting, the teacher can share some curiosities or stories about how data interpretation has been used to solve complex problems or make important decisions. For example, one could mention how data analysis helped combat the Ebola epidemic in Africa, or how the interpretation of meteorological data allows weather events to be predicted accurately. (2-3 minutes)

Development (20-25 minutes)

1. Theory (10-12 minutes)

   • Definition of Data Interpretation: The teacher should begin by explaining what it means to interpret data. They should emphasize that data interpretation is the process of analyzing information presented in graphs and charts to understand what that data represents and what conclusions can be drawn. (2-3 minutes)
   • Components of a Graph: The teacher should explain the basic components of a graph, such as the x and y axes, the legend, the scale, among others. They should also explain what each component represents and how they contribute to understanding the data. (3-4 minutes)
   • Types of Graphs: The teacher should present the main types of graphs used in data interpretation, such as the bar graph, the line graph, the pie chart, among others. For each type of graph, the teacher should explain in which situations they are most appropriate and how to interpret the data presented in them. (3-4 minutes)
   • Reading Tables: The teacher should teach students how to read and interpret information in tables, explaining how to identify the titles of the columns and rows, how to locate a specific piece of data, how to compare data in different parts of the table, among others. (2-3 minutes)

2. Practice (10-13 minutes)

   • Analysis of Graphs and Tables: The teacher should present students with a series of graphs and charts and ask them to analyze them. Students should identify the main components of each graph and table, describe what the data represents, and draw conclusions based on the analysis of the data. The teacher should circulate around the room, providing guidance and clarifying doubts. (5-6 minutes)
   • Group Discussion: After individual analysis, students should be organized into groups and share their conclusions. The teacher should promote a group discussion, encouraging students to express their opinions and listen to the ideas of others. (3-4 minutes)
   • Presentation of Results: Each group should choose a graph or table to present to the class. They should explain what the data represents, how they interpreted the data, and what conclusions they drew. The teacher should provide constructive feedback and correct any errors in interpretation. (2-3 minutes)

3. Theory (3-5 minutes)

   • Critical Interpretation of Data: The teacher should emphasize the importance of interpreting data critically, questioning the information presented and considering possible sources of error or bias. They should explain that data interpretation is not an exact science and that different people can come to different conclusions from the same data. (2-3 minutes)
   • Application of Data Interpretation: The teacher should present some everyday situations in which data interpretation is used, such as when choosing a product at the supermarket, when deciding which route to take to avoid traffic, or when assessing the performance of a soccer player. They should explain how the ability to interpret data can help students make more informed decisions and solve problems more effectively. (1-2 minutes)

Feedback (8-10 minutes)

1. Review and Reflection (3-4 minutes):

   • The teacher should begin this stage by asking students to share their answers and conclusions from the practical activities carried out during the class. Each group should have the opportunity to briefly present the results of their analysis of graphs and tables, and the teacher should provide constructive feedback.

   • Next, the teacher should ask questions to encourage students to reflect on what they have learned. For example, they could ask: "What were the main difficulties you faced when interpreting the data?", "Were you able to identify any trends in the data? How did you come to that conclusion?", "Do you think the interpretation of the data would be different if we were analyzing a longer or shorter period of time? Why?"

   • The purpose of this stage is to get students to stop and reflect on the data interpretation process, identifying their difficulties and gaining a deeper understanding of the subject.

2. Connections with Practice (2-3 minutes):

   • The teacher should then ask students to reflect on how what they learned in class connects to the real world. They could ask questions such as: "How can the ability to interpret data be useful in your daily lives?", "Can you think of examples of real-life situations in which data interpretation is important?"

   • Students should have the opportunity to share their ideas and experiences, and the teacher should encourage everyone to participate. The goal is to show students that data interpretation is not just an academic skill, but something they can use to make more informed decisions and solve problems more effectively in their daily lives.

3. Review of Theory (2-3 minutes):

   • Finally, the teacher should summarize the main points of the class, reiterating the concept of data interpretation, explaining once more the components of a graph and a table, and reinforcing the importance of interpreting data critically.

   • The teacher should also do a brief review of the main types of graphs and charts, and the skills needed to interpret them. They should mention the main difficulties that students faced during the class and provide tips on how to overcome them.

   • The purpose of this stage is to consolidate the students' learning, ensuring that they have understood the concepts and skills presented in class.

Conclusion (5-7 minutes)
