5. Encourage students to actively participate in the lesson, ask questions, and share their thoughts and ideas. This fosters a collaborative learning environment and enhances students’ engagement with the topic.

Introduction (10 - 12 minutes)

The teacher will:

1. Remind students of the previous lessons on Basic Probability, emphasizing the calculation of the probability of single events. The teacher can use a quick review activity, like a short quiz or a problem-solving exercise, to refresh the students' memory and ensure a smooth transition to the new topic.

2. Present two problem situations to the class:

   • The teacher can use a bag of colored candies as a visual aid. The teacher will describe the situation where a student randomly picks two candies from the bag without replacement. The teacher will ask, "What is the probability of getting a red candy and then a blue candy?"
   • The teacher can also use a deck of cards for the second problem. The teacher will describe the situation where a student draws two cards from a standard deck of 52 cards without replacement. The teacher will ask, "What is the probability of drawing a heart and then a diamond?"

3. Contextualize the importance of Compound Events in real-world applications. The teacher can explain that understanding Compound Events is crucial in various fields such as weather forecasting (the probability of rain and wind occurring together), games of chance (the probability of rolling two dice and getting a specific combination), and business decisions (the probability of a marketing campaign being successful if two different strategies are used simultaneously).

4. Introduce the topic of the day with two attention-grabbing stories:

   • The teacher can share the story of Blaise Pascal, a 17th-century French mathematician and physicist, who developed the theory of probability. The teacher can highlight the use of probability in gambling, which led to Pascal's correspondence with Pierre de Fermat and the development of the theory of probability.
   • The teacher can also share the story of the famous Monty Hall problem, a probability puzzle based on a game show. The teacher can engage the students by asking, "If you were a contestant, would you switch your choice?"

5. Present the learning objectives for the lesson and explain that by the end of the lesson, students will be able to solve problems involving Compound Events, both theoretically and practically. The teacher will also emphasize that the skills they will learn are not just for passing tests, but also for making informed decisions in real-life scenarios.

Development (20 - 22 minutes)

The teacher will:

1. Activity 1: The Card Game

   • Divide the students into groups of 3 or 4.
   • Give each group a standard deck of 52 cards and a worksheet with questions related to drawing cards without replacement.
   • Explain that in this activity, students will simulate drawing cards from a deck without replacement. The groups will then calculate the probability of the two drawn cards being of a specified value (e.g., two black cards, a heart and then a diamond, a face card and then an ace).
   • Guide the students in understanding the importance of considering the outcomes of the first event when calculating the probability of the second event.
   • After each group completes the activity, have them share their results with the class. Encourage discussion and address any questions or confusion.

2. Activity 2: The Spinner Game

   • Each group receives a spinner divided into 4 or 6 equal sections, each section colored differently, and a worksheet with questions.
   • Explain that in this activity, students will simulate spinning the spinner twice and calculate the probability of landing on two specified colors.
   • Guide the students in understanding how to use a sample space diagram to visualize all possible outcomes and determine the probability of each.
   • Monitor the groups as they work, providing guidance and support as needed. Encourage students to discuss their thinking and strategies with their group members to foster collaboration and peer learning.
   • After each group completes the activity, have them share their results and strategies with the class. Encourage a class discussion and address any questions or confusion.

3. Activity 3: Flip a Coin and Roll a Die

   • Each group receives a coin, a six-sided die, and a worksheet with problems.
   • Explain that in this activity, students will toss the coin and roll the die, then answer questions about the probability of certain outcomes.
   • Guide the students in understanding how to calculate the probability of two separate events happening together (e.g., getting heads on the coin and rolling an even number on the die).
   • Monitor the groups as they work, providing guidance and support as needed. Encourage students to discuss their thinking and strategies with their group members to foster collaboration and peer learning.
   • After each group completes the activity, have them share their results and strategies with the class. Encourage a class discussion and address any questions or confusion.

The teacher will conclude the development stage by summarizing the key points from the activities and transitioning to the next stage of the lesson. The teacher will also ensure that all students understand the concept of Compound Events and are ready to apply it in the real-world problem-solving stage of the lesson.

Feedback (8 - 10 minutes)

The teacher will:

1. Facilitate a group discussion where each group shares their solutions or conclusions from the activities. The teacher will ask each group to present one problem they worked on, the method they used to solve it, and the results they obtained. The teacher will also encourage other students to ask questions or provide their insights on the presented problem.

2. Connect the findings from the group activities to the theoretical concept of Compound Events in Probability. The teacher will highlight how the students' hands-on experience with the card game, the spinner game, and the coin and die game helped them understand the concept of Compound Events better. The teacher will also emphasize the importance of considering the outcomes of the first event when calculating the probability of the second event.

3. Ask reflective questions to stimulate critical thinking and reflection:

   • What was the most important concept you learned today about Compound Events in Probability?
   • Can you explain how you applied the concept of Compound Events in Probability in the card game, the spinner game, and the coin and die game?
   • Can you think of other real-world situations where you can apply the concept of Compound Events in Probability?

4. Encourage students to share their answers to the reflective questions with the class. The teacher will listen and provide feedback, correcting any misconceptions and reinforcing correct understanding.

5. Conduct a quick, informal assessment by asking a few students to solve a problem involving Compound Events in Probability on the board. The teacher will provide guidance and corrections as needed, ensuring that all students can apply the concept correctly.

6. Summarize the main points of the lesson, emphasizing the importance of understanding Compound Events in Probability for real-life situations. The teacher will also remind students that the concept of Compound Events is based on the outcomes of single events, reinforcing the connection between the current lesson and the previously learned concept of Basic Probability.
