Introduction (10 - 15 minutes)

1. Begin the lesson with a review of prerequisite topics that are essential for understanding the Fundamental Principle of Counting. This may include reviewing factorials, combinations, and permutations, which are foundational concepts that students will need to understand in order to apply the FPC. This can be done through direct questioning of students or via a brief summary on the board.

2. Next, provide students with a couple of example problems that are similar to what they will be working on in class. For instance, one problem could involve counting the number of possibilities in a card game, while another could involve scheduling events on a calendar. Have students attempt to solve these problems, without using the FPC.

3. Introduce the theory of the FPC, explaining that it is used to determine the total number of possible outcomes when there are a series of choices or events. Use simple, everyday examples to illustrate the concept, such as counting the number of possible combinations on a restaurant menu or scheduling events on a calendar.

4. To engage the students and pique their interest in the topic, share some interesting facts about the FPC. For instance, the FPC is one of the fundamental principles of probability theory and has applications in a wide range of fields, from mathematics and physics to economics and biology. Additionally, the FPC was developed by the French mathematician Pierre-Simon Laplace in the 18th century and is considered to be one of the most important contributions to mathematical theory.

5. Finally, connect the Introduction to the lesson by explaining that the goal of the lesson is for students to become proficient in applying the FPC to solve problems similar to the ones presented. Emphasize the importance of the FPC to everyday life, explaining that it can be used to make more informed decisions and predict outcomes in a variety of situations.

Development (20 - 25 minutes)

1. Role-Playing Activity: "Kingdom Creator" (10 - 15 minutes)

   • Divide the class into groups of no more than 5 students each.

   • Provide each group with a large piece of paper, colored markers, and a set of cards. The cards will have images of different elements of a fantasy kingdom, such as characters, settings, animals, plants, magical items, etc. Each card will be unique, meaning there are no duplicates.

   • The goal of the activity is for each group to create their own unique "Fantasy Kingdom" by arranging the cards in a way that makes sense together. For example, they may decide that the "Wizard" character lives in the "Magic Tower" and has a "Pet Dragon". Or, that the "Princess" lives in the "Castle" and has a "Fairy Godmother".

   • However, there are a few rules: The groups cannot use all of the cards at once; they must choose a specific number of cards to use in each arrangement. Additionally, they must use all of the cards throughout the activity, without repeating any.

   • Give the groups a time limit to complete the activity. During this time, the groups should discuss and decide how many cards they will use in each arrangement and in what order the cards will be arranged.

   • When the time is up, have each group present their "Fantasy Kingdom" to the class, explaining their choices. The teacher should then lead a discussion about how the Fundamental Principle of Counting was applied in the activity and how it helped the groups make decisions about how many and which cards to use in each arrangement.

2. Practical Activity: "The Surprise Birthday Party" (10 - 15 minutes)

   • Present students with a new problem scenario: "You and your friends are planning a surprise birthday party for a classmate. You have to decide the order in which everyone will arrive at the party and which gift each person will give to the birthday boy/girl. How would we use the Fundamental Principle of Counting to solve this problem?".

   • Provide each group with a new set of cards, this time representing the friends and the possible gifts. The group must use the FPC to determine all of the possible combinations of arrival order and gifts.

   • Circulate around the room, providing assistance to groups that need help. When the problem has been solved, have each group present their solution to the class, explaining how they used the FPC to arrive at their solution.

3. Group Discussion: Applications of the FPC (5 - 10 minutes)

   • After the activities have been completed, lead a group discussion about the various applications of the Fundamental Principle of Counting in everyday life, science, and technology.

   • Share examples of how the FPC is used in computer programming, data analysis, predicting outcomes in games, scheduling events, probability of events occurring, and more.

   • The goal of this discussion is to reinforce the importance of the FPC to everyday life and to a variety of knowledge domains, as well as to encourage students to think critically about the application of what they have learned.

Return (8 - 10 minutes)

1. Group Discussion: Reflection on the Activities (3 - 5 minutes)

   • Bring the class together for a discussion about the solutions or conclusions that the groups came up with during the activities. Give each group a maximum of 3 minutes to share their experiences and findings with the class.

   • As the groups are presenting, encourage the other students to ask questions and make comments, fostering a collaborative learning environment.

   • After all of the presentations have been made, summarize the main ideas and solutions that were presented, highlighting how each group applied the Fundamental Principle of Counting to solve the problems that were posed.

2. Connecting to Theory: Presentation of Examples (2 - 3 minutes)

   • The teacher should then connect the practical activities back to the theory that was presented at the beginning of the lesson. To do this, provide a few examples of how the FPC was applied to solve the problems in the activities.

   • For example, the teacher could show how the FPC was used to determine the total number of possible arrangements in the "Kingdom Creator" activity or to calculate all of the combinations of arrival order and gifts in the "Surprise Birthday Party" activity.

   • The goal of this step is to reinforce the concept of the FPC and to show students how it can be applied practically and effectively.

3. Individual Reflection: Checking for Understanding (3 - 5 minutes)

   • To wrap up the lesson, have the students complete an individual reflection on what they have learned. Instruct students to think about the following questions:

     1. What is the most important concept that you learned today?
     2. Are there any questions that you still have?

   • Give the students a minute or so to think about their answers. Then, ask a few students to share their reflections with the class.

   • Encourage participation from all of the students, ensuring that everyone has an opportunity to express their opinions and ask questions.

   • Based on the students' responses, determine if there are any concepts that have not yet been fully understood and plan review activities for the next class session.

   • Additionally, use the students' reflections as feedback to assess the effectiveness of the lesson and to identify areas that may need more attention or elaboration in future lessons.
