Elapsed Time Calculation Methods

The video tutorial on Teacher Pro TV covers the concept of finding elapsed time in minutes and seconds. It explains what elapsed time is and provides three methods to calculate it: using a number line, counting minutes or seconds, and subtraction. The tutorial includes an example problem involving Kevin's math activity and offers practice exercises using number lines and tables. The lesson concludes with a recap of the key points.
