AIM: When using a tool, what must you consider?
Announcements: Quiz this Thursday, 3/2/17 Topics: Theoretical probability Experimental probability Sample spaces (using tree diagrams, lists) Compound probability Fair vs. Unfair HW: What Do You Expect textbook: pp.6061 #58 Do Now: Franky is creating a spinner. He has a total of 4 sections on the spinner. Three of them are colored blue and one is red. What is the theoretical probability of landing on each color? Explain? NOTE: Students raised the valid question: "Can we assume all of the sections on the spinner are the same size?" This is a dangerous assumption. When unsure, it's best to give a response that covers all scenarios. Classwork: The focus for today's lesson was fairness. Students needed to use tools (spinners, number cubes, straws, coins, etc) to set up experiments that could be used to fairly select one of three students. The most important thing to consider is how the experiments can be designed so that each student has an equal opportunity of being selected. Resources: Leave a Reply.
