• Promote interaction and collaboration among students through group activities involving discussion and sharing of ideas.
• Stimulate critical thinking and analysis skills of students by examining how different words can be used in different contexts.
• Develop students' confidence in their reading and writing abilities in English through practice and regular feedback.

The teacher should start the lesson by presenting the Learning Objectives to the students, so they are aware of what will be expected of them by the end of the lesson.

Introduction (10 - 15 minutes)

1. Review of Previous Content: The teacher should start the lesson by reviewing the concepts of basic vocabulary in English that were previously taught, including words that are frequently used and familiar to the students. This is essential for students to be able to understand and apply the concept of synonyms and antonyms correctly.

2. Problem Situation 1: The teacher can propose the following situation: "Imagine you are reading a book in English and come across a word you do not know. How could you discover the meaning of this word without having to look it up in the dictionary?" This situation will prepare students for the Introduction of the concept of synonyms and antonyms, demonstrating how these tools can be useful in understanding new words.

3. Contextualization: The teacher should then contextualize the importance of synonyms and antonyms, explaining how the proper use of these words can enrich writing and speaking in English. Additionally, it can be mentioned how lack of knowledge about these concepts can lead to misunderstandings and misinterpretations.

4. Problem Situation 2: Next, the teacher can propose another situation: "Imagine you are writing an important email in English and want to ensure your words convey exactly what you mean. How can you use synonyms and antonyms to make your text more varied and interesting?" This situation will motivate students to learn and effectively apply the concept of synonyms and antonyms.

5. Topic Introduction: Finally, the teacher should formally introduce the topic of the lesson - synonyms and antonyms. It can be explained that synonyms are words that have the same or a very similar meaning, while antonyms are words that have opposite meanings. The teacher can use simple and clear examples to illustrate these concepts, such as "big" and "huge" (synonyms) or "big" and "small" (antonyms).

The Introduction should be designed to spark students' interest and curiosity about the topic, while providing a solid foundation of knowledge for what will be taught next.

Development (20 - 25 minutes)

1. Board Game Activity (10 - 12 minutes): The teacher should divide the class into groups of 4 to 5 students. Each group will receive a board game that has been previously prepared by the teacher. The board game should be designed in a way that students need to advance through the board by correctly answering questions about synonyms and antonyms to reach the end. The questions can be based on contextual sentences, where students need to identify the appropriate synonym or antonym to fill in the blank.

   • Game Preparation: To prepare the board game, the teacher should print or draw a simple board with numbered spaces. In each space, the teacher should write a sentence that contains a word that needs to be replaced by a synonym or antonym. The words that need to be replaced should be written on a separate card. The teacher should then shuffle the cards and place them in a stack next to the board.

   • Activity Execution: The students, in their groups, should roll a die to determine how many spaces they advance on the board. When they land on a space, they pick a card from the stack and try to find the correct synonym or antonym for the word in the sentence. If they answer correctly, they stay on the space, if they answer incorrectly, they go back to the previous space. The first group to reach the end of the board is the winner.

2. Treasure Hunt Activity (10 - 12 minutes): After the Conclusion of the board game, the teacher should conduct a treasure hunt activity in the classroom. In this activity, students should work in their groups to find and write down as many synonyms and antonyms as possible from a list of predetermined words.

   • Activity Preparation: To prepare the activity, the teacher should create a list of words in English that have easily identifiable synonyms and antonyms. For example, the word "happy" can have the synonyms "joyful" and "content", and the antonym "sad". The teacher should then spread cards with these words around the classroom, making sure each word has at least one synonym and one antonym on separate cards.

   • Activity Execution: The students, in their groups, should go around the classroom looking for the words and matching the correct synonyms and antonyms. They should write down the words and their corresponding synonyms and antonyms on a piece of paper. At the end of the activity, the group with the most words correctly matched is the winner.

These playful and interactive activities will allow students to explore the concept of synonyms and antonyms in a fun and engaging way. Additionally, by working in groups, students will have the opportunity to practice their collaboration and communication skills in English.

Feedback (8 - 10 minutes)

1. Group Discussion (3 - 4 minutes): After the Conclusion of the activities, the teacher should gather all students and promote a group discussion. Each group should share the solutions or strategies they used to complete the activities. The teacher should encourage students to explain why they chose certain synonyms or antonyms, and how these words fit in the context of the given sentences or words.

   • Discussion Guidance: The teacher should guide the discussion by asking questions to deepen students' understanding of synonyms and antonyms. For example, the teacher can ask: "How did you decide that this word was the correct synonym/antonym?" or "Why do you think this word cannot be a synonym/antonym in this situation?".

2. Connection to Theory (2 - 3 minutes): Next, the teacher should make the connection between the practical activities and the theory presented at the beginning of the lesson. The teacher can recap the concepts of synonyms and antonyms, and explain how students were able to apply these concepts during the activities. The teacher can also highlight any common errors made by students and explain how these errors can be avoided in the future.

3. Individual Reflection (3 - 4 minutes): Finally, the teacher should propose that students reflect individually on what they learned in the lesson. The teacher can ask questions like: "What was the most important concept you learned today?" and "What questions have not been answered yet?". Students should have a minute to think about these questions and then have the opportunity to share their answers with the class.

   • Student Feedback: The teacher should be open to receiving feedback from students about the lesson. This may include what they liked about the lesson, what was challenging, and what they would like to learn more about in the future. Student feedback can be used to inform the planning of future lessons and ensure that students' needs and interests are met.

By the end of the lesson, students should have a clear understanding of the concept of synonyms and antonyms, and the ability to identify and use them correctly in a sentence context in English. Additionally, they should have had the opportunity to practice their collaboration, critical thinking, and communication skills in English.

Conclusion (5 - 7 minutes)

1. Summary of Contents (2 - 3 minutes): The teacher should recap the main points covered during the lesson, reinforcing the definition of synonyms and antonyms and how they are used in the English language. The importance of expanding vocabulary through knowledge of synonyms and antonyms should be emphasized, and how this skill can enrich communication in English.

2. Connecting Theory with Practice (1 - 2 minutes): The teacher should highlight how the activities carried out during the lesson allowed students to apply the theoretical concept of synonyms and antonyms in a practical manner. It should be emphasized how constant practice of these skills can improve fluency and understanding in English.

3. Extra Materials (1 minute): The teacher can suggest extra materials for students who wish to deepen their knowledge of synonyms and antonyms. These materials may include reference books, language learning websites, online games, or vocabulary apps. The teacher can also suggest that students practice identifying synonyms and antonyms in English texts they regularly read.

4. Topic Importance (1 minute): Finally, the teacher should reinforce the relevance of the topic covered for students' daily lives. It can be explained that the ability to identify and use synonyms and antonyms can improve students' written and oral communication in English, making their interactions more varied and interesting. Additionally, understanding synonyms and antonyms can facilitate reading and understanding English texts, especially those containing more complex vocabulary.

The teacher should conclude the lesson by reiterating the Learning Objectives and encouraging students to practice what they have learned in their self-study activities. Additionally, the teacher should be available to answer any final questions from students and provide additional clarifications, if necessary.
