In this lesson for grades 4-7 from Cyberchase — the program that shows kids that math is everywhere and everyone can be good at it! — students are introduced to concepts of fairness in games based on the probability, or odds, of winning and losing a game of chance. It includes media resources, assessment materials, and Common Core State Standards.This lesson plan is motivated by a Cyberchase video segment in which the CyberSquad plays a fair game of chance called the Squares Game and one game created by Hacker.
