About these elapsed time worksheets

Elapsed time is how much time passes from the start of something to the end. In 3rd grade children tell time to the minute and solve problems about time intervals in minutes, such as how long soccer practice lasts or what time a movie ends.

A time number line makes these problems easier to see. Children mark the start and end, then jump to the next hour or quarter hour and add the jumps. These worksheets use clocks and number lines marked every 5 minutes, then move on to finding end times, start times and word problems within the hour and across the hour.

Clocks are drawn precisely, with the hour hand moving between the numbers as the minutes pass. Every practice page has an answer key on page 2.

Standards

  • CCSS.MATH.CONTENT.3.MD.A.1Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram.

How to use them

  1. Teach with the Elapsed Time Chart: jump to the next hour, then on.
  2. Sheet A pages stay inside one hour; Sheet B pages cross the hour.
  3. Use the number line pages for children who lose track counting on a clock.
  4. Find the End Time and Find the Start Time practice counting forward and back.
  5. The Day Camp Schedule brings it together with a real-life table.

Teaching tips

  • Crossing the hour is the hard part. Jump to the :00 first, then add the rest.
  • Count back for start times: 30 minutes before 8:10 is back 10 to 8:00, then back 20 more.
  • There are 60 minutes in an hour, not 100. 9:45 to 10:15 is 30 minutes, not 70.
  • Use a real clock or a geared practice clock alongside the sheets.

Questions teachers and parents ask

What is elapsed time?

The amount of time that passes between a start time and an end time. From 9:40 to 10:25 the elapsed time is 45 minutes.

What is the easiest way to find elapsed time?

Use an open number line: put the start time on the left, jump to the next hour, then jump to the end time, and add the jumps.

Do 3rd graders work with hours and minutes?

Third graders mostly find intervals in minutes. These sheets keep answers in minutes, including intervals that cross the hour.
