This resource focuses on helping students master the concept of calculating elapsed time using number line strategies. The learning goal is to enable students to determine elapsed time for various scenarios, including those that span across the same day or cross midday/midnight. The document outlines clear success criteria, which include identifying start and end times, depicting jumps on a number line, labeling those jumps, and summing the total duration. Several worked examples illustrate how to effectively calculate elapsed time, as seen with a scenario involving Sarah who read from 2:15 PM to 4:45 PM. Students are also provided with numerous independent practice problems to reinforce their skills as well as strategies for cases involving crossing the midday and midnight transitions. Lastly, a metacognitive checklist and challenge extensions are included to heighten students' understanding and application of the concepts.
