**Unit 7, Lesson 3, Investigation 1 and 2 Review**

__Standards and Benchmarks Covered in this Lesson__

VI,1,1:
Develop an understanding of randomness and chance variation and describe chance and certainty in the language of probability.

VI,1,2:
Give a mathematical definition of probability and determine the probabilities of more complex events, and generate and interpret
probability distributions.

__Introduction__

1) Anticipatory
Set: Student Quote and discussion (overhead: "Probability Distributions, wait times, independent events, what is all this
stuff?")

2) Objectives:
"We need to figure out what is going on here with Probability Distribution tables and graphs, and the relationship between
the two. And we need to talk about Rare Events."

__Presentation__

3) Input:
Probability Distribution (Def)- at a glance tells the probability of all possible events.

? "Do we know how to display probability at a glance?"

? What have we done in the past?

4) Modeling
(review)/Guided Practice: 2 examples on the overhead/board

(students' help)

v Rare Event (def)- any probability ≤ .05 or 5%

5) Check for
Understanding:

v Check Point Pg 500: class discussion

v M.O.R.E problems on their own in class

__Guided Practice__

6) Guided
Practice: (modeling review above with student input)

__Independent Practice__

v Recap the lesson for students'Tool Kits -Probability Distributions (graphs, tables, interpretations) and Rare Event

7) Finish M.O.R.E.S at home in review for quiz tomorrow.
