Lesson 20 — Activity 1: Sports and Time
Getting Ready
For a lot of people, the clock rules their day. An alarm wakes many people up, and from that point on until they go to bed, they check a clock to see what time it is. How long before school begins? How much time is left before lunch? Is this class
ever going to be over? There is a game at 7:30 tonight; how much time is there to spend with friends before I have to leave to get there? People ask themselves these types of questions all day; even if they don't think consciously about it.
This
lesson is about time in everyday situations. It will concentrate on three areas: sports, work, and cooking. All three of these have specific requirements when it comes to time.
Try This:
Do you spend a lot of the day thinking about time? Keep a list for one day to see how often you ask yourself a question about time.

This first activity will look at sports and time.
Everyone, at some point in life, will play a sport that involves time as a factor. This may be as simple as your physical education teacher yelling that you have 5 minutes left and you know you are down one point. This may motivate you to play harder
to try to tie the game up.
Or, it may be as complicated as representing your city or town in a particular sport and knowing that every second counts when trying to win a game. Just look at the NHL.

Time is so important in their games that in the last minute of every period, they don't just count the seconds; they count the tenths of seconds! Goals to tie or win games have been scored with less than one second on the clock when the puck has crossed
the goal line!
With any serious game that involves a set time period, there is an event called "clock watching," and it is always interesting to observe the players doing it.
If you are up by a single goal, you constantly watch the clock. You may be thinking it must be broken because it is going so slow and the game will never end! But, if you are losing, every time you glance at the clock, time seems to be passing too
quickly!
As a fan, it is important to know how to figure out how much time has gone by. This is called elapsed time. And how much time is left. This is called remaining time. This will allow you to enjoy the game on a whole new level.
Let's look closely at the game of hockey.
Each period in hockey is 20 minutes long. In North America, the time clock counts down to zero, while in other parts of the world, it counts up to 20 minutes. We will use the North American clock in our
example.

Let's say a goal is scored at 10:47 in the third period and you want to know how much time has elapsed in the period. You can figure it out this way:
1. You know there are 60 seconds in a minute, so deal with the seconds
first.
60 – 47 = 13
Thirteen seconds have elapsed in this minute.
This brings the time back up to 11 minutes.
2. Now you can calculate the number of minutes that have
elapsed. Remember there are 20 minutes in a period and there are 11 minutes left in the period.
20 – 11 = 9
Nine full minutes have elapsed in the period.
3. Put the full number of minutes and the seconds together to tell how much time has elapsed.
9 minutes + 13 seconds
Nine minutes and 13 seconds have elapsed in the period.
What about the CFL? A football game has four 15-minute quarters. Just like the NHL, the clock starts at 15 minutes and counts down to zero.

Let's say one team has kicked a field goal with 4:04 left in the second quarter and we want to know how much time has elapsed since the game started.
1. Once again, you know there are 60 seconds in a minute, so let's deal
with the seconds first.
60 – 4 = 56
Fifty-six seconds have elapsed in this minute.
This brings the time back up to 5 minutes.
2. Now you can calculate the number of minutes that have elapsed.
Remember there are 15 minutes in a quarter and there are 5 minutes left in the quarter.
15 – 5 = 10
Ten full minutes have elapsed in the quarter.
3. Put the full number of minutes and the seconds together to tell how much time has elapsed.
10 minutes + 56 seconds
Ten minutes and 56 seconds have elapsed in the quarter.
4. Since you are in the second quarter and we want to know how many minutes have elapsed since the
game started, you will have to add 15 minutes for the first quarter.
15 minutes + 10 minutes = 25 minutes
Twenty-five minutes and 56 seconds have elapsed since the game started.
In both of the examples above, the clock counted down to zero. The remaining time is simply whatever the clock says at that time.
