## Calculating Elapsed Time

#### Aligned To Common Core Standard:

**Grade 3 Measurement** - 3.MD.A.1

What is Elapsed Time? When you are tutoring your children about time, you need to tell them the difference between the recorded time and the time of interval. 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. The elapsed time, by definition, is the time taken to complete a race or the time to reach a destination. Learning to find the elapsed time is important since it's used extensively in our daily lives. This series of worksheets and lessons help students learn to determine the gap of elapsed time between two events.
