Elapsed Time: Find the Start Time: what children learn

Finding a start time means working backward from the end time. Students count back in jumps, often to the nearest hour first, and then take away the minutes that are left.

Elapsed Time: Find the Start Time: worked example

The show ends at 3:50 and lasts 35 minutes. What time does it start? 3:15

Count back 20 minutes from 3:50 to get to 3:30. Count back 15 more minutes to get to 3:15. So the show starts at 3:15.

Elapsed Time: Find the Start Time: a common mistake to watch for

Kids often add the minutes instead of counting back, so they write a start time that is after the end time.

Elapsed Time: Find the Start Time: how to help at home or in class

Make a leaving-the-house plan together: the bus comes at 8:10 and getting ready takes 25 minutes, so when must you begin? Your child moves backward on a clock or a number line, stopping at the hour first. Then check by counting forward again, and the two answers should meet. Let them plan weekend trips the same way. When they switch easily between going forward and going back, they are ready for longer spans.
