Elapsed time worksheets

Elapsed time asks how long an event lasts rather than what time appears on a clock. Students must connect a start time and an end time, cross an hour when necessary, and express the duration accurately. These worksheets generate daytime intervals of up to two hours and calculate every answer with integer minutes.

Choose thirty-, fifteen-, five- or one-minute precision to match the learner's current level. Each question presents the start and end in a consistent digital format, leaving room to show a number line, make an open-clock sketch or count forward in friendly chunks. The matching answer key uses hours and minutes when appropriate.

Strategies students can use

• Count forward from the start time to the next hour, then continue to the end time.
• Draw an open number line and record each jump in hours or minutes.
• Convert both times to minutes, subtract, and convert the difference back to hours and minutes.
• Check that the duration is reasonable by comparing it with the two-hour maximum on the sheet.
• Use five-minute intervals before moving to times that require counting individual minutes.

Teaching across an hour boundary

Many errors occur when an interval crosses the next hour. Model a question such as 9:45 to 10:20 by making a 15-minute jump to 10:00 and a 20-minute jump to 10:20, then adding the jumps. Encourage students to write the intermediate hour so they do not subtract clock digits as though times were ordinary base-ten numbers.
