4. Introduction to the Topic:

   • The teacher can introduce the lesson topic with some curiosities or interesting facts. For example, it can be mentioned that the multiplication operation is the basis for many other mathematical operations, such as exponentiation and rooting.
   • Another curiosity is that multiplication can also be seen as a form of repeated addition, which can help better understand the concept.
   • Finally, the teacher can share that the division operation is a way to share equal quantities, which is very useful in many everyday life situations.

Development (20 - 25 minutes)

1. Theoretical Explanation (10 - 12 minutes)

   • The teacher should start by explaining what multiplication and division operations are, and how they relate to each other.
   • Multiplication is an operation that combines two or more numbers into a single number, while division is an operation that divides a number into equal parts.
   • It should be emphasized that multiplication is the inverse operation of division and vice versa. For example, if 3 x 4 = 12, then 12 ÷ 4 = 3.
   • The teacher can use visual examples, such as arrangements of dots or squares, to illustrate the idea of multiplication and division as repeated addition and sharing equal quantities.
   • Still in the theoretical part, the teacher should explain the terms involved in multiplication and division operations, such as multiplicand, multiplier, dividend, and divisor.

2. Guided Practice (5 - 7 minutes)

   • The teacher should then guide students in solving some problems involving multiplication and division operations.
   • To do this, simple problems should be started and gradually increase in complexity, ensuring that students are following the reasoning and understanding the process.
   • The teacher should explain step by step how to solve each problem, emphasizing the choice of the correct operation, the execution of the operation, and the interpretation of the result.

3. Practical Application (5 - 6 minutes)

   • After guided practice, students should be encouraged to solve problems on their own.
   • The teacher can give students a list of problems to solve, with different levels of difficulty, and walk around the room to help and clarify doubts.
   • The problems should be designed to challenge students to apply the acquired knowledge in a meaningful and contextualized way.

4. Discussion (5 - 7 minutes)

   • After students have had the opportunity to solve the problems, the teacher should lead a classroom discussion to review the solutions and clarify any remaining doubts.
   • The teacher should reinforce the main concepts and the importance of multiplication and division operations in everyday life.
   • This is also an opportunity for the teacher to correct any common errors and provide constructive feedback to students.

This lesson development allows students to learn actively and engaged, through exploration, practice, and application of the presented concepts. In addition, the classroom discussion helps reinforce learning and promote a deeper understanding of the content.

Return (8 - 10 minutes)

1. Group Discussion (3 - 4 minutes):

   • The teacher should organize students into small groups and ask them to discuss the solutions to the problems proposed in the Practical Application stage.
   • Each group should be encouraged to share their conclusions with the class, explaining how they arrived at the answers and what strategies they used.
   • During the discussion, the teacher should walk around the room, listening to different ideas and clarifying any doubts that may arise.

2. Connection with Theory (2 - 3 minutes):

   • After the group discussion, the teacher should revisit the theoretical concepts presented at the beginning of the lesson and show how they apply to the discussed problems.
   • For example, the teacher can explain how the idea of multiplication as repeated addition was used to solve a problem, or how division was used to share a quantity equally.
   • The goal here is to ensure that students see the relevance and applicability of theoretical concepts, thus strengthening their understanding.

3. Individual Reflection (2 - 3 minutes):

   • To conclude the lesson, the teacher should propose that students reflect individually on what they have learned.
   • The teacher can ask some questions to guide the reflection, such as: 'What was the most important concept you learned today?' and 'What questions have not been answered yet?'.
   • Students should be encouraged to write down their answers, as this can help them consolidate what they have learned and identify any areas that may need further study or practice.

4. Teacher's Feedback (1 minute):

   • Finally, the teacher should provide overall feedback on the lesson, highlighting strengths and areas that still need to be worked on.
   • The teacher should also reinforce the main concepts and remind students to continue practicing multiplication and division operations at home.

This Return is crucial to the learning process, as it allows students to reflect on what they have learned, make connections with theory, and receive constructive feedback. In addition, group discussion promotes collaboration and critical thinking, skills that are essential not only for mathematics but for life in general.

Conclusion (5 - 7 minutes)

1. Content Summary (2 - 3 minutes):

   • The teacher should start the Conclusion by summarizing the main points of the lesson. This includes defining the operations of multiplication and division, their relationship as inverse operations, and how they are used to solve real-world problems.
   • It is important for the teacher to reaffirm the idea that multiplication is a form of repeated addition and division is a way to share equal quantities.
