Elapsed Time Problem Solving

This video tutorial covers the concept of elapsed time, explaining how to calculate it using timelines and examples. It includes scenarios like Emma's homework, a magic show, baking a cake, and more. The video emphasizes the importance of understanding AM and PM distinctions and provides strategies for solving elapsed time problems using addition and subtraction. The tutorial concludes with a preview of the next lesson on mixed measures.

What is the importance of understanding elapsed time in problem-solving?

• It is necessary for understanding fractions.
