About the Elapsed Time Worksheets

Elapsed time is the amount of time that passes between a start and an end: how long practice lasts, or when the cake comes out of the oven. It is hard for one reason. Time is counted in sixties, so the subtraction children already know gives wrong answers. From 2:50 to 3:10 is 20 minutes, and subtracting gives 60.

The method on these sheets avoids subtracting. On a number line, jump from the start time to the next whole hour, then by whole hours, then the minutes left, and add the jumps. The How It Works chart shows it on one example from start to finish.

The first two worksheets keep it simple so the idea is clear: whole and half hours, then minutes within the same hour. Elapsed Time on a Number Line puts the two together for times that cross several hours. Every problem shows both clocks and both digital times, so reading the clock is not the hard part.

Real problems do not always ask how long. Find the End Time and Find the Start Time give the amount of time and ask for the other end, and the word problems mix all three kinds. Children need to read a clock to the minute first, which the telling time worksheets cover. Blank number lines are handy for extra problems.

Frequently Asked Questions

What is elapsed time?
Elapsed time is how much time passes between a start time and an end time. If a movie starts at 2:30 and ends at 4:15, the elapsed time is 1 hour 45 minutes.
How do you find elapsed time?
Count up from the start time in jumps. First jump to the next whole hour. Then jump by whole hours. Then jump the minutes that are left to reach the end time. Add the jumps. From 2:15 to 4:20: 45 minutes to 3:00, 1 hour to 4:00, 20 minutes to 4:20, which is 2 hours 5 minutes.
Why can’t you just subtract the times?
Because an hour has 60 minutes, not 100. Ordinary subtraction borrows 100 when it should borrow 60, so the answer comes out wrong whenever the end minutes are smaller than the start minutes. Counting up in jumps avoids the problem.
What grade learns elapsed time?
Elapsed time is taught in 3rd grade, where students solve problems with time intervals in minutes, often on a number line. Simple versions in whole and half hours appear in 2nd grade, and harder problems continue in 4th grade.
How do you find the start time?
Count back from the end time. If something lasted 40 minutes and ended at 3:20, go back 20 minutes to 3:00 and then 20 more to 2:40. The start time is 2:40.
What happens when the time crosses 12 o’clock?
Keep counting. After 12:00 comes 1:00. From 11:45 to 2:05 is 15 minutes to 12:00, then 2 hours to 2:00, then 5 minutes: 2 hours 20 minutes in all.
