Time - Comparing the duration - Presentation

The lesson on 'Comparing the Duration' is designed to teach students how to assess and compare the lengths of different events. The key concept introduced is 'duration', which refers to the amount of time an event takes from start to finish. Students will learn to use inequality symbols such as less than (<), greater than (>), and equals (=) to compare the durations of various activities. For instance, they will examine a class daily timetable, identifying the longest and shortest lessons by comparing start and finish times. Maths, starting at 7:30 a.m. and ending at 9:00 a.m., is identified as the longest lesson, while P.E., from 1:00 p.m. to 1:30 p.m., is the shortest. Students will also determine how much longer one lesson is compared to another, deepening their understanding of time measurement.

Further activities challenge students to apply their knowledge using the inequality symbols to compare different time periods, such as school hours or the duration of train journeys. They will complete sentences to articulate the duration differences, for example, stating that the journey to London is longer than the journey to Manchester by a specific amount of time. The lesson also includes reasoning exercises where students evaluate statements related to time, such as determining the winner of a race based on completion time or identifying errors in calculating the length of a school day. Such exercises enhance critical thinking and ensure students grasp the practical applications of comparing durations in everyday contexts.
