Number of Cellphones Throughout a Lifetime
In this lesson, students will begin by reflecting on their own experiences with cell phones, using prompts such as "How many cell phones have you had in your lifetime?" and "How often do you upgrade your cell phone?" This will help them gather personal data to explore. After collecting data points, students will analyze the information and determine the best mathematical equation (linear, quadratic, exponential, etc.) to model the data. Once they have identified the appropriate equation, they will use it to predict how many cell phones they might own at various ages. To wrap up, students will engage in a group discussion reflecting on the proper disposal of old cell phones and explore potential careers in electronics recycling, connecting the lesson's mathematical focus with real-world applications in sustainability and microelectronics.
Core Content: Mathematics, Algebra II
