Grade 8, Math
Std #14:
Determine the theoretical probability of an event.
  • Calculating the probability of complementary events and mutually exclusive events
  • Comparing experimental and theoretical probability
  • Computing the probability of two independent events and two dependent events
  • Determining the probability of an event through simulation

Lesson Plans:

How Many Cells are Born in a Day?
Students attempt to predict the number of cells that result from a series of cell divisions. They then graph the results to represent their findings.

Monty's Dilemma: Should You Stick or Switch?
This lesson presents a version of a classic game-show scenario: You pick one of three doors in hopes of winning the prize. The host opens one of the two remaining doors, which reveals no prize, then asks if you wish to "stick or switch." Which choice gives you the best chance to win? The approach in this activity includes guesses, experiments, computer simulations, and theoretical models.

Bouncing Tennis Balls
In this lesson, students will develop their skills in collecting and recording data using the real-world situation of a bouncing tennis ball. They will use the data collected to formulate the relationship between the dependent and independent variable in their experiment. This lesson incorporates a student handout and links to a variety of web resources.

Look Airplane
Students design a simple aircraft, to measure the distance it travels, and to calculate the median, mean, and mode of the distances measured.

Surveying The Right Left
Students administer a survey of family members that are right- or left-handed.

Number by Number, Which Team is Best?: 
Using the Internet, students will access information and statistics about professional basketball teams and explore correlations between player characteristics and performance.

Students will collect, organize, and interpret data using the methods of exploratory data analysis; and will understand and apply the basic notions of probability and average.

The Cereal Box Problem - A lesson in Expected Value: 
Suppose there was one of six prizes inside your favorite box of cereal. How many boxes of cereal would you expect to have to buy, to get all six prizes? Includes computer simulation.

Hermit Epidemic:
Simple model of infectious disease transmission.

Let's Make a Deal Math:
A web quest that explores the probability of winning various types of games.

Winning is the Sweetest Reward: 
In this simulation, students will work independently to record and organize chance data based on a given situation.

How Sharp is Your Memory
Students will be asked to recall as many items as they can from each set in a certain length of time. Students will collect, organize, and interpret this data through several statistical methods.

Probability and Simulation
Students play paper basketball and compare and contrast theoretical probability with experimental probability.

 

Resources:

CPS K12
This is a structured lesson plan that provides strategies for teaching, examples, worksheets, and assessments. (Day 60)

The Best and Worst of Statistical Graphics: 
Examples of good and very bad statistical graphs.

Cut The Knot
Interesting articles on real-life misuses of statistics.

Math Talk
An article on the misuses of statistics

The Monty Hall Paradox: 
Online version of the "Let's Make a Deal" dilemma of sticking with your original choice or switching to what's behind door number 2.

The Birthday Problem:
A short lesson in probability:  Applet that address the probability of two people in a class having the same birthday.
