  1. Elapsed Time By Mrs. Stephanie Estes

  2. Elapsed Time is the amount of time that passes from the start of an activity to the end of an activity.

  3. For example: You want to figure out how much time you spend in school each day. If your school day starts at 8:00 am and ends at 3:00 pm, how much time is that?

  4. Next are some ways that you can find the answer!

  5. School starts at 8:00 am and ends at 3:00 pm, how much time is that? Count Forward on the clock. Start End

  6. School starts at 8:00 am and ends at 3:00 pm, how much time is that? Count Forward on the clock. Start End

  7. School starts at 8:00 am and ends at 3:00 pm, how much time is that? Count Forward on the clock. 7 hours End

  8. School starts at 8:00 am and ends at 3:00 pm, how much time is that? Count backwards on the clock. 7 hours End

  9. Use Military Time 24 13 23 22 14 21 15 20 16 17 19 18

  10. A military clock continues counting after 12:00 noon. 24 13 23 22 14 21 15 20 16 17 19 18

  11. A military clock continues counting after 12:00 noon. Like this 24 13 23 22 14 21 15 20 16 19 17 18

  12. A military clock continues counting after 12:00 noon. Like this 24 13 23 22 14 21 15 20 16 17 19 18

  13. Think about it like a subtraction problem. Just remember: - 1 hour is equal to 60 minutes. So when you regroup, you need to add 60 to the total number of minutes, not 10 as you may be used to doing. - Add 12 to the p.m. time to get your military time. So in this problem 3:05 pm becomes 15:05 Find the elapsed time from 7:45 A.M. to 3:05 P.M.
