ENGAGE
Number of hours _1/2_
1. Show the 1-minute video, or the teacher can simulate the activity shown in the video inside the blog below.
http://blog.mrmeyer.com/?p=9553
After the video ask the question, Is there more Sprite in the Coke or more Coke in the Sprite? Have the student’s journal about this and make a choice. Then compare answers with the group.
2. Conduct the experiment described below with a partner.
1. Place 10 red cards and 10 black cards face down in separate piles.
2. Choose some cards at random from the red pile and mix them into the black pile.
3. Shuffle the mixed pile.
4. Return the same number of random cards (face down) from the mixed pile to the red pile.
5. Are there more red cards in the black pile or black cards in the red pile (count them)?
6. Repeat steps 1-5 several time choosing different numbers of cards.
7. As a class, discuss how this experiment helps answer the Coke/Sprite problem above.

EXPLORE Teacher provides guidance for the explorations to prepare students with the knowledge and skills to engage in the task. Students will self-assess on the prior knowledge and skills assumed for the unit
Number of hours_3_
Activity 1 (HO#1a-f): Students will do a station activity where they explore and remediate probability and fairness. The teacher will circulate and help groups as needed.
For the stations to work smoothly our suggestion is to have circulating groups of three to four students. Students are to advance when they have completed the requirements for that station. For the stations that take longer than then other have two to three stations set up.
Stations HO#1 a-f: 1. Coin toss
2. Pick a Card (with and without replacement) 3. Paper, rock scissors
4. Rolling dice 5. How Many Ways? 6. Spinner
Answer Key for Stations 1-6 HO#1g
Activity 2: Geometric Probability:
At the amusement park, Tom’s favorite game is played by tossing a coin onto a large table that has been ruled into congruent squares. If a coin lands entirely within a square, he wins a prize. What is the probability that a randomly tossed coin will win given that the coin’s diameter is 2 cm. and the squares have sides of 5cm.
Have students simulate this and find the experimental probability.
Then have students calculate the theoretical probability. Encourage the students to draw a picture to help solve the problem and redirect as needed. (The theoretical geometric probability is the ratio of the area of the feasibility region over the area of the sample space or for this problem 9/25)
Activity 3: The Birthday Paradox. This activity and teacher instructions are described in the link below:

calculator can be found at the website above.
There is also a random birthday generator at the following website: http://www-stat.stanford.edu/~susan/surprise/Birthday.html
Activity 4: The Monty Hall Problem
Imagine that the set of Monty Hall’s game show Let’s Make a Deal has three closed doors. Behind one of these doors is a car; behind the other two are goats. The contestant does not know where the car is, but Monty Hall does. The contestant picks a door and Monty opens one of the remaining doors, one he knows doesn’t hide the car. If the contestant has already chosen the correct door, Monty is equally likely to open either of the two remaining doors. After Monty has shown a goat behind the door that he opens, the contestant is always given the option to switch doors. What is the probability of winning the car if he/she stays with his/her first choice? What if he/she decides to switch?
The following 4 minute clip from the television show Numbers

EXPLAIN
Teacher introduces the main task of the unit and prepares students to in small group independent work...
Number of Hours_1/2_
Discuss going to a county fair and ask if students have ever played games. Discuss the games that they have played and how
successful they were in winning. Show one of the videos below. (Both videos describe how carnival games are often unfair. The first video is about 10 minutes and the second video is 2 minutes)
ABC 20/20 Carnival Game Expose (10 minutes) http://www.youtube.com/watch?v=PMSSYipFfg4
ABC News with Diane Sawyers-Carnival Scam (3 minutes) http://youtu.be/NIN6Zp6M5lk
After the video, have the students reflect on the games that they have played at fairs and carnivals in their journals. Discuss whether “fairness” was a problem in the games that they played.
The teacher will assign students to groups of three to four students.
The teacher will launch the project by sharing the following documents and providing the following instructions.
1. The final project is to create 2 games that will be used as part of a school-wide fair. In order to be accepted for the fair the students must build the game and have peers play the game. In addition, the principal who is a former high school math teacher wants to know if the game is fair.
2. Write a memo to the principal that includes:
A written description of the games’ probability and the mathematics used to determine the probability.
An explanation of whether the game is fair with supporting evidence.

Students develop their games of chance, calculate the probabilities, and test for fairness. Students then write their memo to the
principal.
Students review the rough draft of the memo to the principal with the teacher, before completion of the project. Students should refer to the rubrics listed below to be sure they know what is expected of them.
