5th Grade Strategies for Your Toolbox to Help Solve Problems Involving Time

2. Let’s Review – Counting Minutes
There are 12 numbers around the face of
a clock.
Each number represents a set number of
minutes past the hour.
So, to figure out the
number of minutes,
you can count by 5s.

3. How to Tell Time to the Minute5
Count the minutes
by 5. 10 15
2.Then count the minutes
by ones. 20 21 22 23

4. How to Tell Time to the Minute5
3. Now read the hour hand. 10 15
4. Then say 1:23 or 23 minutes after 1. 20 21 22 23

5. Let’s Review – Counting Minutes
Example: When the minute hand is on the 6,
it is 30 minutes past the hour
Tip: Multiply 6 x 5 = 30; the minute is on the
6 and we are counting by 5s
So, to figure out the
number of minutes,
you can count by 5s.

6. Practice Calculating Minutes
If the minute hand is on the
3, how many minutes past
the hour is it? 15
How about on the 7? 35

7. Practice Calculating Minutes
How about on the 11? 55
Multiply 11 x 5 = 55 minutes
How about on the 9? 45
Multiply 9 x 5 = 45 minutes

8. Are there any questions???
You are doing a great job!!
Let’s continue…

9. Telling Time Lingo
When the minute hand rotates around one time, a hour has past.
When the minute hand points to 12, it is
exactly an hour. Whatever number the hour
hand points to is the hour.
When the hour hand is between the hours,
we can say it is “half-past” the hour.
When the hour hand points to the 3, it has
gone a quarter way around; we can say it is
“quarter-past” the hour.

10. Telling Time Lingo
When the hour hand points to the 9, it has gone three quarters around; we can say it is a “quarter ‘to” the hour.

11. Different Ways to Say the Time
o'clock
An hour = 60 minutes & therefore can be divided into 4 parts.
The parts are divided by the 0, 15, 30, & 45 minute marks as shown in the picture.
quarter past
quarter to
half past

12. Different Ways to Say the Time
o'clock
Each of the 4 parts are called quarters.
When the # of min. is greater than 30, instead of saying the # of min. after the hour, you can say the # of min. before the next hour, or the # of min. to the hour.
quarter past
quarter to
half past

13. Different ways to say the same time…
We could say that it is 3:45
We could say that it’s a quarter to 4.
The hour hand is between 3 and 4.
The minute hand is three quarters around the clock.
o'clock
quarter to
quarter past
half past

14. We are almost finished
You are amazing……..I knew you could do it.

15. What is elapsed time?
Elapsed time is the time or difference between a beginning time and an ending time.
Finding elapsed time is an important skill in everyday life.
Determining elapsed time requires understanding how to read a clock and understanding how we measure time.

16. Elapsed Time
Write the time it will be in 2 hours?
3:10 _____ 5:35 _____ 12:04 _____
Write the time it will be in 4 hours?
7:11 _____ 6:42 _____ 11:05 _____
5:10
7:35
2:04
11:11
10:42
3:05

17. Practice Finding Elapsed Time
4:00 to 4: :00 to 11:45
7:30 to 8:10 9:15 to 10:20
8:20 to 8:25 4:10 to 5:15
3:55 to 4: :25 to 2:30
30 min.
45 min.
50 min
1 hr 5 min
1 hr 5 min
5 min.
2 hrs 5 min.
5 min.

18. 5:35

19. 12:50

20. 5 minutes 43 seconds 1 minute = 60 seconds Divide 343 seconds
by 60 seconds
343 ÷ 60 = 5 R 43
5 minutes 43
seconds

21. 2 15 minutes = 1 quarter hour 1 half hour = 30 minutes
1 half hour = 2 quarter hours
4 qtr hrs ÷ 2 qtr hrs = 2 half hrs

22. 52
1 year = 52 weeks
