Time of Your Life Project


Here is the "Time of  Your Life" grid that I did



  1. How many days or years do you spend doing all of these activities over the course of your lifetime? How much time do you have left in the end?

Over my lifetime, I will spend around 27, 375 days eating, sleeping, working and doing screen time. In the end, I have 1,825 days for doing other things.

  1. How does this make you feel? How would you want to spend those years?
It makes me feel how short life really is, and there are only four activities on the grid! I thought I would have more time doing the things I like.
I would spend the remaining years hanging out with friends, traveling the world, and exercising.


  1. Do you feel these estimates accurately reflect the time you will spend doing each activity in your own lifetime? If not, how would your own answers change the amount of time you have left over?
The estimates on the worksheet reflect how much time I will spend doing those activities, except for screen time. Right now, in a week, I have an average of 4 hours of screen time instead of the estimate that is given to you (5 hours). So in the grid above, I changed my estimate to 4 hours. If I would have been doing screen time for 5 hours a day, I would have so much less time doing other things I like.



  1. How did you use unit rates to solve this problem? What was difficult for you? What was easy?
I used unit rates to change the numbers from minutes in a lifetime, to days in a lifetime. To get to days, I multiplied 60 minutes (one hour) by 24 (because there are 24 hours in a day) and got 1440. So I divided my dividend by 1440 to get how many days you do one of the activities in your lifetime.

Something that was difficult for me was colouring the squares on the grid. Because they were so small, you could make many mistakes. It was also difficult because some of my numbers had tens and ones digits, so I needed to be very precise.
Something that was easy was working with the total number of minutes. It was easy to convert to minutes, compared to hours.

Unit Rates

How do unit rates help solve problems? 

Unit rates show a quantity of one unit of measurement. They are important as they can reveal a lot of information. We can use unit rates to find out which food has the best price, or the speed per minute or hour.  It can also show statistics for a sports game. Examples of unit rates are 1 apple per dollar, 2 feet per second and 4 goals per hour. 
My notebook shows examples of how we can find a unit rate for mL of coke per dollars. Model A shows that 3,960 mL of coke costs $8.50. To find out how many mL is one dollar, we divide the mL by the cost: 3,960 ÷ 8.50 = 465.88mL/dollar.  So for one dollar, you can get 465.88 mL of coke.
