Objectives (5 - 7 minutes)

1. Introduce and familiarize students with the concept of counting, encouraging the counting of objects in their immediate environment.
2. Teach students to count numbers from 1 to 10 in a fun and interactive way, using toys, games, and practical activities.
3. Develop students' ability to recognize and write numbers from 1 to 10, promoting familiarity with numerical symbols.

The teacher should establish these objectives clearly and simply for the students, ensuring that they understand what is expected to be learned by the end of the lesson.

Introduction (10 - 15 minutes)

1. Recalling previous content: The teacher starts the lesson by recalling mathematical content that has already been learned by the students, such as the identification and writing of numbers from 1 to 5. This is done in a playful way, with the teacher showing cards with numbers and the students saying out loud which number it is.

2. Problem situations: The teacher presents two problem situations related to counting. The first one is as follows: 'Imagine we have 5 apples on the table. If we eat one, how many apples will we have left?' The second situation is: 'If we have 3 soccer balls and we receive 2 more, how many balls will we have in total?' The teacher encourages the students to think and discuss the answers.

3. Contextualizing the importance of counting: The teacher explains that counting is an important skill in everyday life. He mentions situations where counting is used, such as counting the students in the classroom, counting the days until a special event, counting the points in a game, among others.

4. Introducing the topic with curiosities: To spark the students' interest, the teacher can share some curiosities about counting. For example, he can say that counting is one of the first mathematical skills that humans learn, and that it is a skill we use every day. Another curiosity is that the way we count can vary in different cultures - for example, in some cultures people start counting from the thumb, instead of the index finger as we mostly do.

By the end of this stage, students should have a clear understanding of what counting is and why it is an important skill. They should also be excited to explore and learn more about counting.

Development (20 - 25 minutes)

1. Activity 1: Counting Friends: The teacher divides the students into small groups and hands out cards with drawings of children and numbers from 1 to 10. Each group receives a different number of cards. The goal of the game is for the students to count the number of children on each card and place the card with the corresponding number next to it. The group that completes the task first, wins. This activity helps students practice counting, associating quantities with numbers, and teamwork.

2. Activity 2: Hidden Numbers: The teacher hides cards with numbers from 1 to 10 around the classroom. The students, in turns, must find the cards and say out loud which number they found. The teacher can vary the activity by asking the students to find the numbers in ascending or descending order. This activity helps students practice identifying and reading numbers.

3. Activity 3: The Story of Numbers: The teacher creates a simple story involving the numbers from 1 to 10. For example, 'Once upon a time, there were 5 birds on a tree. Then, 2 birds flew away. How many birds remained on the tree?' The students must use counting to solve the problem. This activity helps students connect counting with real-life situations.

These activities are designed to be fun and engaging, encouraging students to learn through practice and experimentation. The teacher should walk around the classroom, observing and guiding the students as needed. By the end of the development stage, students should have a clear understanding of how to count up to 10, recognize numbers, and associate quantity and number.

Feedback (10 - 12 minutes)

1. Group Discussion (5 - 7 minutes): The teacher gathers all students for a group discussion. Each group will have the opportunity to share their findings and solutions from the activities. The teacher encourages students to explain how they arrived at their answers, promoting the practice of mathematical communication. During the discussion, the teacher asks questions to check students' understanding, such as 'Why did you place the number 5 next to that image?' or 'Why do you think the number 10 was the most difficult to find?'.

2. Connection to Theory (2 - 3 minutes): The teacher then makes the connection between the practical activities and the theory. He reinforces that counting is an important skill in mathematics and in everyday life. He emphasizes that counting is not just about reciting numbers, but also about understanding the relationship between numbers and quantities. The teacher can ask questions like 'When we count, what are we really doing?' or 'Why is it important to know how to count?'.

3. Final Reflection (3 - 5 minutes): To end the lesson, the teacher proposes that students reflect on what they have learned. He asks two simple questions for students to answer individually. The first question is: 'What was the most fun part of today's lesson?'. The second question is: 'What did you learn about counting that you didn't know before?'. Students have a minute to think about their answers. Then, the teacher calls on some students to share their answers with the class.

This feedback moment is important to consolidate students' learning and for the teacher to assess the effectiveness of the lesson. By the end of the lesson, students should be able to count from 1 to 10, recognize and write numbers correctly, and understand the importance of counting.

Conclusion (5 - 7 minutes)

1. Summary of Contents (2 - 3 minutes): The teacher recaps the main points of the lesson, reinforcing the concepts of counting, identification, and writing of numbers from 1 to 10. He highlights the importance of counting in everyday life and how it applies to different situations. The teacher can do this in a playful way, asking students to repeat the counting song they learned or to show with their fingers the counting from 1 to 10.

2. Connection between Theory and Practice (1 - 2 minutes): The teacher explains how the practical activities carried out in the lesson helped reinforce the theoretical concepts. He mentions how the 'Counting Friends' activity allowed students to practice counting and associating quantities with numbers, while the 'Hidden Numbers' activity helped strengthen the identification and reading of numbers. The teacher also emphasizes how the 'Story of Numbers' activity allowed students to connect counting with real-life situations.

3. Extra Materials (1 - 2 minutes): The teacher suggests some extra materials for students who wish to deepen their knowledge of counting. He may recommend children's books that address counting in a fun and interactive way, such as 'The Number Book' by Sarah Mestrey. The teacher can also suggest online games or educational apps that help practice counting, such as 'Counting Game' or 'Counting with Fingers'.

4. Importance of the Subject (1 minute): Finally, the teacher reinforces the importance of counting, explaining that it is a fundamental skill in mathematics and in everyday life. He mentions that counting is used in various situations, from counting objects to solving simple mathematical problems. The teacher encourages students to continue practicing counting at home and at school, reminding them that the more they practice, the stronger their counting skills become.

This conclusion stage is important to consolidate students' learning and to motivate them to continue exploring and learning about the subject of counting. The teacher should ensure that students know he is available to help with any questions or difficulties that may arise.
