Jelly Belly has a game called Jelly Belly BeanBoozled, where identical colored jelly beans have two different flavors, one pleasant and one not so pleasant. This lesson guides students through some class and individual work where they determine whether it is a "fair" game (whether the probability of choosing a pleasant jelly bean equal the probability of choosing a not pleasant jelly bean). You may be surprised by the results! ;)
Teachers will need to supply students with Jelly Belly BeanBoozled jelly beans which can be purchased at various stores such as Walmart and Amazon. You do not need to buy a complete Jelly Belly BeanBoolzled game and can instead buy refill packs and find an image of the spinner that comes with the game online to show your students.
I used this document to teach this lesson for a formal observation from my administrator and both he and my students loved it. A lot of fun and learning took place that day...and no one got sick...which was a minimal risk I was aware I was taking during the observation. ;) I didn't make all students participate in the taste testing and instead let students choose if they wanted to participate and even allowed them to choose which color jelly beans (knowing the potential flavors they might get) they each tasted.
This 7 page document guides students through 9 tasks to complete the taste testing, make various calculations involving probability, determine whether the game is fair, and write paragraphs about their findings and conclusions.
The document includes project instructions, tables to help students organize their data, and white space for students to work calculations and answer questions.
