LESSON PURPOSE:This lesson plan introduces linear equations by having a group of students model real, quickly-gathered class data. The goal is to help motivate student interest in data collection, graphing, linear equations, and slope, while minimizing the time normally needed to collect data in other contexts.This is a .zip file including an editable PowerPoint of the lesson, a PDF of the slides that can be distributed or uploaded, a PDF of the teacher notes that the instructor can refer to as
