DIGITAL LINK: LINEAR EQUATIONS PROJECT
Ever wonder how much your phone really costs over time? In this project, we become cost detectives!
Students will explore different cell phone plans, write equations to show how the price adds up each month, and make graphs to see the pattern. Then, we will survey friends and family about their phone plans and create scatter plots to look for trends. Using linear regression, students will discover how math can actually predict the cost of a plan and learn that real-world data doesn’t always fit perfectly, just like real life!
