1. Topic

Probability
Section 13.1 and 13.3 


2. Content

OUTCOME: a possible result of an experiment.
EVENT:a collection of outcomes.
FAVORABLE OUTCOMES: desired outcome.
ProbabilityABILITY: ratio of the number of favorable outcomes to the number
of possible outcomes.
COMPLEMENTARY EVENTS: two events having no outcomes in common and
if together they contain all the possible outcomes.
INDEPENDENT EVENTS: two events are independent if the occurrence of
one event does not affect the likelihood that the other event will
occur. 


3. Goals: Aims/Outcomes

1. Define outcome and favorable outcome.
2. Be able to find a probability.
3. Know the difference between probability and independent probability. 


4. Objectives

1. Class is engaged and taking adequate notes. (Props: *ZoomThat
answer took flight & *Woo WooRight on Track and Cold Call)
2. Students can respond individually and as a group.
3. Students can find and describe Probability. 


5. Materials and Aids

13.1 and 13.3 packet
Paper & Writing instrument 


6. Procedures/Methods

A. Introduction
THE HOOK: What is the probability of having your M&M drawn?
1. What is probability?
(entertain 12 responses) *Handout packets
2. 13.1 Choose readers using cold call. VOCAB
3. Give and get 24 examples of Probability. EX: gender, eye color,
outfit, lottery, scrabble letter, M&M, games 


B. Development
1.Discuss Probability 1/2(boy/girl)& EX 1 in Packet (COLD CALL)
2.Discuss EX 2 in packet (CC)
3.Discuss EX 3 in packet (CC)
IF TIME ALLOWS
4.Discuss tree setup with student notebooks. (NT P292)
5.Discuss Examples 1 in packet for 13.3 


C. Practice
1.Use dice to discuss Probability
(specific #, #<>#)
2.Use namesDescribe Probability and reveal letter. Student chooses a letter
and then we choose 23 names.
3.Include Complementary events by summing ratios to = 1. Ex: vowels/consonents
or #<4 / #>4. 


D. Independent Practice
1.Quiz 1 AB P157 14
2.TIME?: Quiz 1 AB P157 5/6. 


E. Accommodations (Differentiated Instruction)
1.NO OPT OUT
2. Add another option to the notebook tree



F. Checking for understanding
Class responses to the original question: What is the Probability
your name will be drawn when everyone submits 1 entry. Class? One
grade level? School? Write as a ratio, decimal and percent. 


G. Closure
1.Call and Response to vocab
2.HW complete Challenge Practice 13.1 110 and 13.3 15
