Grade 4 - Measurement - Elapsed Time Timeline and Overall Addition

In this video, we explore an elapsed time problem, focusing on how to determine the end time of an activity using a timeline or number line. We walk through the steps of breaking down the problem into manageable parts, adding time in increments, and ensuring that time calculations are accurate.

The video highlights the importance of visualizing time with a number line to make the concept more concrete and understandable for students. Additionally, we demonstrate how to check the work using a different strategy, reinforcing the idea that time can be tricky but manageable with the right tools.
