Estimating Probabilities by Collecting Data

Curated and Reviewed by Lesson Planet

Take a spin to determine experimental probability. Small groups spin a spinner and keep track of the sums of the spins and calculate the resulting probabilities. Pupils use simulated frequencies to practice finding other probabilities to finish the second instructional activity in a series of 25.

Instructional Ideas
  • Before calculating the actual probability, have individuals determine the likelihood of the event occurring
Classroom Considerations
  • Make copies of four-segmented spinners for the class
  • Learners need to know how to convert fractions to percents
Pros
  • Includes sample data to demonstrate how to determine the solutions
  • Highlights the section of the lesson where the mathematical practice is used
Cons
  • None
