#WODB Equations Warm-Up

Which One Doesn't Belong? Let's start a "math fight"! In this brief activity, students are given four equations with variables on both sides of the equals sign (emphasis on distribution). Using Desmos Card Sort, students must take a stand on which equation they believe doesn't belong, and justify this choice. Students will see what other students choose, and consider different opinions and justifications. Additionally, students have the opportunity to create their own #WODB task to share. Which one do YOU think doesn't belong? Why? #WODB inspired by http://wodb.ca
