This document discusses converting between units of time including seconds, minutes, hours, and days. It provides examples of converting smaller and larger units by dividing or multiplying by the appropriate conversion factor. For example, 120 seconds is equal to 2 minutes because 120 seconds divided by 60 seconds/minute equals 2 minutes. It also includes practice problems for students to solve involving converting between units of time.

8. 60 seconds = 1minute
60 minutes = 1hour
24 hours = 1 day
What is the equivalent of
seconds to minute, minutes to
second and hours to day?

PROBLEM SOLVING

10. It rained continuously for 3 days
and nights. How many hours did it
rain?
24
x 3
1
2
7 hours

11. Cora slept for 180 minutes.
How many hours did it rain?
180 60 3 hours

12. Mariel worked on her project in
300 minutes. How many hours did
Mariel work on her project?
300 60 5 hours
300
minutes
5 hours

13. 120 seconds = 2minutes = 120 ÷ 60 = 2
120 minutes = 2 hours = 120 ÷ 60 = 2
72 hours = 3 days = 72 ÷ 24 = 3
How did we change:
Which are the larger units of time?
Smaller?
What should we do when we change a
smaller unit to a larger unit?:
divide
Smaller ÷ larger

14. 5 minutes = 300 seconds 5x 60 = 300
5 hours = 300 minutes 5 x 60 = 300
5 days = 120 hours 5 x 24 = 120
How do we change larger unit to a
smaller unit?
multiply
Lager x smaller

15. GUIDED PRACTICE

16. Read and solve:
Francis drove for 2 hours in going to
his grandparents’ house. How many
minutes did he drive? ___________________
Miguel stayed in the library for 240
minute. How many hours did he stay in
the library?

17. Marlon spends one and one half hour
in playing? How many minutes does he
spend in playing? __________________
Marian waited for her friend for four
hours. How many minutes did Marian
wait?______

18. Therese watched TV for 180
minutes. How many hours did she watch
TV?__________

19. GENERALIZATION

20. When we change a smaller unit to a
larger unit you divide.
Second to minute ÷ 60
Minute to hour ÷ 60
Hour to day ÷ 24
How did we change smaller units to
large units?

21. When we change a larger unit to a
smaller unit you multiply.
Minutes to second X 60
Hour to minute X 60
Day to hour X 24
How did we change larger units to
smaller units?
