⏰ Total Time: 60 minutes

Stop losing time reteaching 7th Grade Compound Probability and show students how to determine sample space and calculate compound events using real probability experiments.

This structured lesson walks students from simple probability review to modeling compound events with tables, tree diagrams, and organized lists.

🎯 Learning Objectives

Students will be able to:

• Determine the sample space of compound events

• Calculate compound probabilities using favorable outcomes over total outcomes

• Represent probability outcomes using tables, tree diagrams, and organized lists

• Apply probability reasoning to real-world probability experiments

📦 What’s Included ⏰

• Sample Spaces of Compound Events Worksheet (PDF)

• Probabilities of Compound Events Worksheet (PDF)

• Hands-on probability experiments using dice, candy selections, and letter draws

• Modeling demonstrations using tables, tree diagrams, and organized lists

🛠️ How to Use / Lesson Structure ⏰

1️⃣ Probability Warm-Up (5 min)

Students calculate simple probability using a candy selection and a six-sided die roll.

2️⃣ Teacher Modeling (10 min)

Introduce compound events and compound probability.

Model how to build sample spaces using:

• Tree diagrams

• Tables

• Organized lists

Students see that all models produce the same sample space outcomes.

3️⃣ Guided Practice (10 min)

Students work with partners to complete the Sample Spaces of Compound Events Worksheet, identifying all possible outcomes.

4️⃣ Independent Practice (20 min)

Students complete the Probabilities of Compound Events Worksheet, calculating probabilities as simplified fractions.

5️⃣ Performance Assessment (10 min)

Students determine the sample space and probability for selecting a candy and a labeled letter.

6️⃣ Review & Strategy Reflection (5 min)

Students explain how they determined sample space size and compound probabilities.
