Flipping Out: Calculating Probability with a Coin Game
Degner, Kate
Mathematics Teaching in the Middle School, v21 n4 p244-245 Nov 2015
In the author's experience with this activity, students struggle with the idea of representativeness in probability. Therefore, this student misconception is part of the classroom discussion about the activities in this lesson. Representativeness is related to the (incorrect) idea that outcomes that seem more random are more likely to happen. This probability activity builds on students' experience with the common practice of coin flipping. In particular, the activity addresses the grade 7 Common Core State Standards for Mathematics (CCSSM) in probability and statistics (CCSSI 2010). Students calculate the probability of simple and compound events by using an organized list or probability tree. Additionally, the activity provides the opportunity for students to confront potential misconceptions about probability.
