Lesson Plan | Active Learning | Probability Predictions

Assumptions: This Active Lesson Plan assumes: a 100-minute class, prior student study with both the Book and the start of Project development, and that only one activity (among the three suggested) will be chosen to be conducted during the class, as each activity is designed to take up a significant portion of the available time.

Objectives

Duration: (5 minutes)

The Objectives stage is essential to clearly establish the learning goals for the class. By defining clear and specific objectives, students can better direct their focus and efforts during practical activities. In this stage, the teacher should ensure that students understand the purpose of studying probabilities, emphasizing how these concepts apply in real and curious everyday situations.

Main Objectives:

1. Empower students to apply probability concepts to predict outcomes in simple experiments like tossing a coin, rolling a die, and drawing a card from a deck.

2. Develop logical reasoning and critical analysis skills when evaluating the likelihood of events occurring in everyday situations.

Side Objectives:

1. Encourage active participation of students in solving problems in groups, promoting collaboration and discussion.

Introduction

Duration: (15 - 20 minutes)

The Introduction serves to engage students and review prior content on probability, using problem situations that they should have already studied. Additionally, it seeks to connect the subject to real and curious situations, increasing interest and relevance of the theme. This initial approach sets the stage for a more in-depth and practical application of the concepts during the class.

Problem-Based Situations

1. Imagine you are playing 'heads or tails' with a friend. If you flip the coin five times, what is the probability that it lands 'heads' exactly three times?

2. If you roll a fair die, what is the probability of getting an even number? And if you roll two fair dice simultaneously, what is the probability that the sum of the results is 7?

Contextualization

Probabilities are present in many everyday situations, from predicting the weather to calculating the chances of winning the lottery. For example, when deciding whether to take an umbrella based on the weather forecast, we are applying notions of probability. Additionally, in games like poker, understanding probabilities can be the difference between winning or losing. Understanding these concepts helps make more informed decisions and better understand the world around us.

Development

Duration: (70 - 75 minutes)

The Development stage aims to allow students to practically and creatively apply the probability concepts studied through playful and contextualized activities. By working in groups, students also develop collaboration and communication skills. This stage is crucial for consolidating theoretical learning in practical and real situations, ensuring a deeper and more lasting understanding of the topic.

Each group will choose a game of chance, such as 'heads or tails', 'dice', or 'deck of cards', and must design a fair game, determining the rules and the probabilities of each possible outcome. After creation, the groups will present their games to the class, which will be able to try them out.

- Instructions:

• Form groups of up to five students.

• Choose a game of chance to work on (heads or tails, dice, or deck of cards).

• Design the game, defining the rules and calculating the probabilities of each outcome.

• Prepare a presentation to explain your game and its probabilities to the class.

• Hold a game fair, where each group presents their game and the other students can play to test the probabilities.

Activity 2 - Card Challenge

> Duration: (60 - 70 minutes)

- Objective: Develop calculation skills and understanding of probabilities in card games, and promote teamwork and creativity.

- Description: In this activity, students will explore the probabilities involved in a card game. Each group will receive a deck of cards and must create a card game that involves predicting probabilities. Students will need to calculate the chances of victory in their game and test it with classmates to see if the probabilities hold true in practice.

- Instructions:

• Divide the class into groups of up to five students.

• Give a deck of cards to each group.

• Guided by the teacher, students should create a card game involving probability prediction.

• Calculate the probabilities of victory in the created game.

Activity 3 - Probability Theater

> Duration: (60 - 70 minutes)

- Objective: Explore the use of probabilities in real situations, develop communication and presentation skills, and reinforce the understanding of probabilities through practical contexts.

- Description: Students will put together small plays that involve everyday situations where probabilities play a crucial role. Each group will choose a scenario, such as deciding whether or not to take an umbrella based on the weather forecast, and will act out the situation, discussing the probabilities involved with the audience.

- Instructions:

• Organize students into groups of up to five.

• Each group chooses an everyday scenario involving probabilities.

• Write a theater script that highlights the decisions and probabilities involved in the chosen scenario.

• Prepare and rehearse the play.

• Present the play to the class, discussing the probabilities with the audience.

Feedback

Duration: (10 - 15 minutes)

This stage of the lesson plan is crucial for consolidating learning. Through group discussion, students have the opportunity to verbalize and reflect on what they have learned, as well as hear the experiences and solutions of their peers. This not only reinforces understanding of probability concepts but also develops communication and argumentative skills. The discussion allows the teacher to assess the students' level of understanding and clarify any remaining doubts, ensuring that all learning objectives have been achieved.

Group Discussion

To start the group discussion, the teacher can ask each group to share their findings and challenges encountered during the activities. It is suggested that the teacher use guiding questions to steer the conversation, such as: 'What were the biggest difficulties your group faced in calculating the probabilities in the games?', 'How did you apply the probability concept to improve the game you created?' and 'Was there any situation where the calculated probabilities did not hold true in practice? How do you explain that?'

Key Questions

1. What are the main applications of probabilities in the games you created?

2. How can the notions of probability be used in everyday life to make more informed decisions?

3. Was there any surprise regarding the probabilities calculated during the activities? Why?

Conclusion
