Gettys Middle School, Easley, S.C. U.S.A.
Materials Required: Media and Materials to be used in the lesson: Media and Materials to be used in the lesson:
Activity Time: Broken down over several days.
Concepts Taught: The students will be able to discuss the origin of probability; investigate to compare and contrast

The teacher will need fifteen computers for the students to be able to access the Internet for a probability web quest that was designed the teacher. This web quest will teach the origin of probability; theoretical and simulated probability; computing the probability of two independent events; and mutually exclusive events. The plain paper, rubric and colored pencils are to be used to create a probability book incorporating all the components of probability.

The instructional strategy for this product appeals to the students sense of adventure. The probability activities involve sports, shopping, and the stock market. There are some activities that have a game show theme as well. Before the students begin their web quest, they will brainstorm real-life situations that deal with probability. After the brainstorming session, the students will participate in a web quest that will enable them to research the origin of probability. (See below for web resources) They will then participate in a question and answer session. This web quest will also enable them to participate in activities that will develop an understanding of theoretical and simulated probability. The students will individually create a Venn Diagram comparing and contrasting the two, then they will write a report based on their Venn Diagram. When the students have completed the activity from the web quest computing independent events in pairs, they will turn in their work for a formal assessment. After the students complete the web quest, they will individually create a probability book by writing their own probability situations involving theoretical and simulated probability as well as situations involving the probability of two independent events. They will also discuss their understanding of mutually exclusive events in this book.
(See "Variations/Options", for evaluating students performance.)
Before the students begin their web quest, they will brainstorm real-life situations that deal with probability.

Evaluate student performance:
During the informal question and answer session, The teacher will ask the students to write down on their paper the answers to the following questions:
1. Why was probability originated?
2. Who developed probability?
3. In what time frame was
probability originated?

The teacher will have Popsicle sticks with the names of the students in the class written on each stick. He/She then pull a Popsicle stick to randomly call on students to share their answers.

The Venn diagram will be graded on the accuracy of comparing and contrasting theoretical and simulated probability. If the students can correctly compare and contrast 4 out of the 5 components (80%), then they will have met the objective.

Students will have to compute the probability of two independent events with 80% accuracy. These questions will be found throughout the web quest.

As students are working on their web quests, The teacher will go to each pair of students and ask them to show me an example of a mutually exclusive event. They will then tell how they know that it is a mutually exclusive event.

The probability books will be scored with the following rubric. The students must score a 3 or above to show mastery.

(1) Several of the problems are not completed.

Strategy/Procedures
(4) Typically, uses an efficient and effective strategy to solve the problem(s).
(3) Typically, uses an effective strategy to solve the problem(s).
(2) Sometimes uses an effective strategy to solve problems, but does not do it consistently.
(1) Rarely uses an effective strategy to solve problems.

Mathematical Terminology and Notation (4) Correct terminology and notation are always used, making it easy to understand what was done.
(3) Correct terminology and notation are usually used, making it fairly easy to understand what was done.
(2) Correct terminology and notation are used, but it is sometimes not easy to understand what was done.
(1) There is little use, or a lot of inappropriate use, of terminology and notation.

Make a note for revision in the future.

Evaluate media components:

Ask several colleagues to try the web quest either individually or with their students. Their feedback will help evaluate the web quest. Also rely on the feedback from students.

Make a note for revision in the future.

Evaluate instructor performance:
Evaluate performance in two ways: analyzing the academic achievement of students, and student feedback.

Make a note for revision in the future.

So, you like to take risks, huh? Did you know that the probability concept was originated to settle gambling disputes? To find out more about the origin of probability, visit http://www.cc.gatech.edu/classes/cs6751_97_winter/Topics/stat-meas/probHist.html
. Answer the following questions on a piece of paper:
1. Why was probability
originated?
2. Who developed probability?
3. In what time frame was
probability originated?
Now that you have learned some interesting historical things about probability, it is time to learn about the difference between experimental probability and theoretical probability at http://www.mathgoodies.com/lessons/vol6/intro_probability.html .
Here you will enjoy an interactive lesson of tossing dice and spinning spinners to discover the exciting world of probability. While you are participating in this activity, be sure to decide whether or not the events are mutually exclusive.
Now that you know something about probability are you ready to play a game? Visit http://www.shodor.org/interactivate/activities/chances/ to play the "Crazy Choices Game," where you have control over the entire experiment. After you have conducted your experiments, you will then compare the experimental and theoretical probability results. After you have completed this activity, create an individual Venn Diagram comparing and contrasting theoretical and experimental probability. Write a report based on your Venn Diagram.
If you are a racing fan, you will enjoy the next activity. Go to http://www.shodor.org/interactivate/activities/racing/ for an exciting probability game that involves a race between you and your partner.
After this race, you are probably feeling pretty competitive right now. GREAT!!
