Converting Time
This lesson deals with converting one form of time to another (for example, minutes to seconds or hours to days). If students remember the basic conversion chart for time, they should be fine. They memorized a rap for linear measurement (you can find it on that page) that will help them convert time as well. They need to remember: Big to little gotta multiply; little to big divide. The conversion chart for time is provided below with some practice problems. There are word problems at the bottom of the page to help students understand the concept as well.
Time Conversion Chart
60 seconds = 1 minute
60 minutes = 1 hour
24 hours = 1 day
7 days = 1 week
52 weeks = 1 year
12 months = 1 year
365 days = 1 year
If the question is ______ min = 4 hours
Students should see that they are going from hours (big) to minutes (little), and they need to multiply the number they are given (4) by the number of minutes in an hour (60). Four times sixty is 240. Therefore, 240 minutes is the same amount of time as 4 hours.
If the question is 180 sec = _______ min
Students should see that they are going from seconds (little) to minutes (big), and they need to divide the number they are given (180) by the number of seconds in a minute (60). 180 divided by 60 is 3. Therefore, 180 seconds is the same amount of time as 3 minutes.
