Our Probability Lesson Plan explores the concepts of probability, including the definition of probability and how to use fractions to determine event probability. The interactive tracking activity engages the sensory system with the use of coins, dice and a spinner, as well as stimulates discussion, collaboration, and written expression. Generalize the concept of probability by discussing various actions that carry a low probability of success.
Sample Classroom Procedure / Teacher Instruction
- Ask students: Have you ever played a game using dice and hoped you rolled a certain number? Do you think you had a better chance of rolling one number instead of another number? How do you know?
- Allow for responses and discussion. Ask students if they have ever taken chances and to give an example. Why did they pick one choice over another?
- Allow for responses and discussion. Introduce chance as it relates to probability.
- Distribute Probability content pages. Read and review the information with the students. The use of examples with dice or a spinner would be helpful. Stress the independence of each spin, coin toss, etc. Save the final question for lesson closing. Use the additional resources to enhance understanding.
- Distribute Activity page. Read and review the instructions. Pair students. Distribute coin, dice, and 4-number spinner. Encourage students to take turns when they spin, toss, and roll, and to count and track the results carefully and neatly. Circulate during the lesson to ensure students stay on task. Tell students to think about each question before writing their responses, discussing it between each other. Once students have completed the activity, each pair of students should share at least one of their results. Using the Coin Toss Totals, record the class total. Discuss the overall results.
- Distribute Practice page. Check and review the students’ responses.
- Distribute the Homework page. The next day, allow students to share the results of the number picking and their conclusions.
- In closing, ask: Tell about something you chose to do that had a low probability of success. Why did you do it?
- Allow for responses and discussion. The discussion could include people sometimes need to take chances or risks in life, even if there is a low probability. Other times, a risk may lead to problems.
