Time - Elapsed Time, Negative - Intro

In this math unit, students start by developing skills in calculating negative elapsed time between two clock times and advance to manipulating negative time durations with increasing complexity. Initially, they learn to identify the difference in hours and minutes between two times and gradually learn to calculate new times after subtracting full hours or minute intervals from a given starting time. As the unit progresses, exercises involve more detail such as half-hour and quarter-hour increments, enhancing students' ability to compute and comprehend time differences visually and numerically. Towards the end, the challenges present scenarios requiring precise subtraction of time, demanding more exact and speedier calculations. This progression builds a strong foundation in understanding and managing reversed time durations, underscored by practical problem-solving of real-life relevance.
