Elapsed Time Word Problems Challenge

Mrs. Bridges explains how to solve elapsed time word problems using a number line. She covers three types of problems: those with known start and end times, those with a known start time and duration, and those with a known end time and duration. The lesson uses the concept of 'mountains' and 'hills' to represent hours and minutes, respectively, on a number line. By the end, students should be able to confidently solve elapsed time problems.
