Lesson Title: Probability Lesson 2 / Date
Learning Goal (Curriculum Expectations)
- demonstrate, through investigation, an understanding of fairness in a game and relate this to the occurrence of equally likely outcomes
- predict the frequency of an outcome in a simple probability experiment or game then perform the experiment, and compare the results with the predictions, using mathematical thinking
Lesson Components / Anticipated Student Responses
Before
Kareem is playing a game using the spinner below. If the arrow lands on an R, Kareem wins. How many times should Kareem expect to win in he spins the arrow 10 times?
/ How do you know?
During
Please look at the spinner below. Estimate how many times the spinner will land in the shaded area for 10 spins. Then spin the spinner 10 times and record your actual spins.
How many times did the spinner land on the shaded area? Why do you think the spinner landed on the shaded area that many times? Explain your thinking.
After (Consolidation)
Choose several students to explain their thinking.
What was your estimation?
Did the estimation and actual number of spins match? Why or why not?
How can you predict how many times the spinner will land on a specific area of the spinner?
What strategy can help you predict the number of times a spinner will land on a specific area?
After (Highlights and Summary)
Highlight the key language the students use. Co-create the Success Criteria
- know the language of probability, use information from the spinner to make predictions, find relationships between the number of spins and area covering the spinner, use fractions to determine fair share
