How much of your life do you spend tying your shoes? Brushing your teeth? What about sleeping and eating? And in the end, how much of your life can you spend doing the things you really enjoy?
In this lesson, students use proportional reasoning and unit rates to calculate how much of their total lifespan they can expect to spend on different activities. After accounting for necessities like sleeping, eating, and working, they estimate how many days of their life they have left over, and discuss how they’d like to spend that time.
