## Reflection: Student Grouping Job Offers and Cell Phone Plans: Making Informed Decisions with Mathematics - Section 3: Collaborative Work: Cell Phone Plans

For this group work, I ask students to compare and contrast the cost of two different cell phone companies. The prompts are open ended so students need to assess their own cell phone use to determine which of the two plans would better suit their cell phone use.

When teaching this activity, I found that the group work helped foster students in collegial debate, and also impacted students ability to engage in the crucial critical thinking skill of compare and contrast

I want students to learn how to be smart consumers of knowledge. By providing opportunities to debate and discuss differing opinions with classmates, students have an opportunity to practice comparing and contrasting and using evidence to justify their claims. It is my hope as a teacher that providing time in the class to foster these skills will support students not only in future math classrooms, but also in their future college and career endeavors.
