Elapsed Time: Find the End Time: what children learn

Students add minutes to a start time by jumping to the next hour and then adding what is left, or by counting on a number line. Since 60 minutes make an hour, minutes over 59 turn into a new hour.

Elapsed Time: Find the End Time: worked example

The show starts at 2:30 and lasts 45 minutes. What time does it end? 3:15

From 2:30 to 3:00 is 30 minutes. 45 - 30 = 15 minutes are left, so the show ends at 3:15.

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

Kids often add the minutes straight onto the minutes and write 2:75, forgetting that 60 minutes make a new hour.

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

Use a real kitchen task: say it is 5:40 and the pasta needs 35 minutes, then ask when dinner will be ready. Your child walks the minute hand forward on a toy clock, pausing at the next whole hour to see how many minutes are left to add. Try different starting times each day. Once they are right on times that pass the hour, they can tackle finding a start time.
