# Elapsed Time Worksheets

Having a good understanding of how much effort or time is required to do something is a fundamental lead toward delineating a sense of value. If something requires a humongous amount of time, it often carries a great deal of value with it. In order to determine the length of time that occurs between two events, usually the start and end of something, we use a basic equation that finds the difference between the starting and ending time of the event. This series of worksheets and lessons help students learn to determine the gap of elapsed time between two events.

### Aligned Standard: 3.MD.A.1

- Paul's Music Class Step-by-Step Lesson- How long does Paul go to music for?
- Guided Lesson - The scenarios include math class, sleeping, and the length of an annual school function.
- Guided Lesson Explanation - I like to break into hours and minutes. Students just need to remember that both carry to each other.
- Practice Worksheet - Very practical questions that relate to a typical young person's day.
- Matching Worksheet - I use the Hour.Minute notation for time here because it is used in different tests beside the standard colon.

- Answer Keys - These are for all the unlocked materials above.

### Homework Sheets

You should find a series of problems that rings with kids here.

- Homework 1 - Colin goes to his sports class at 5:00 P.M. and he returns at 7:30 P.M. How long was his sports class?
- Homework 2 - Martin went to his friend's house for dinner. He returned to his home at 7:30 P.M. If he spent 2 hours and 30 minutes at dinner, what time did he get to his friend's home?
- Homework 3 - Joe goes to play football at 1.00 P.M. He stops his game at 4 P.M. How long did he play football?

### Practice Worksheets

A great skill to throw in here is to have students estimate the time it would take to complete the activity.

- Practice 1 - Victoria goes to buy a refrigerator at 3:30 P.M. She comes home at 5:30 P.M. How long did she take to buy refrigerator?
- Practice 2 - William was busy reading comic books since 9:00 A.M. He completes reading comic books at 10:15 A.M. How long did he read for?
- Practice 3 - Scott was busy doing office work since 3:00 P.M. He completes his office work at 7:00 P.M. How long did he take to complete his work?

### Math Skill Quizzes

When writing these, I followed the basic premise that you need to have a start and finish activity.

- Quiz 1 - Lena goes to office at 11:00 P.M. She comes home at 6:15 A.M. How long did she works for?
- Quiz 2 - Gloria goes to the bus stop at 8:00 A.M. She comes home at 10:00 A.M. How long does she stay at the bus stop for?
- Quiz 3 - Angelica goes to the college at 8:00 A.M. She comes home at 11:40 A.M. How long did she stay at college for?

### What is Elapsed Time?

When you are tutoring your children about time, you will often need to tell them the difference between the recorded time and the concept of a time of interval. They can often be vastly confused, and the core difference can have a huge impact on the decisions that you make based upon those values. The tricky part is that time is not represented in the form of decimals, with the highest limit on the minute chart is 60. For instance, if we want to calculate the difference between time, such as 2:10 - 1:20, then the result is 0:50.

Elapsed time, by definition, is the time between the start and finish of some event. In less complex language it is the amount of time something takes. Learning to find the elapsed time is important since it's used extensively in our daily lives. It all comes down to understanding when something starts and when it ends. This can be measure in seconds, minutes, hours, days, and even years. Time is really one of those things in life that you can never get back. You will want to learn how to calculate elapsed time to understand if a certain event is worth your attention.

To determine elapsed time all you need to do is determine the exact time of the start and the end of the event of interest. The basic equation to calculate this is: elapsed time = ending times – starting time. Because we use standard time and not military time, often, that can confuse things if the differences rolls either over noon or midnight. Just remember that the roll over occurs at the 12 place and you should be all good to go.
