Time - Finding the duration - Presentation

In a comprehensive set of teaching slides, students are introduced to the concept of finding the duration of various events, with a particular focus on understanding and calculating time intervals. The lesson begins by prompting students to consider the minutes in a full turn of the minute hand around the clock, setting the stage for the subsequent activities. The primary objective is for students to use their knowledge of hours and minutes to calculate the duration of different TV programmes, with start and finish times provided. For instance, they would determine that "Jim’s Kingdom" runs for 1 hour, starting at 6:30 and finishing at 7:30, while "Imagination Creation" lasts for 3 hours, from 15:15 to 18:15.

Further activities require students to apply their skills in different contexts, such as calculating the time spent running. They are given start and stop times and must work out the duration in minutes, for example, Esin ran from 7:20 a.m. to 8:45 a.m., which is 85 minutes. The lesson also challenges students to think critically about whether it is necessary to count each minute individually or if there are more efficient methods to determine the duration. In one scenario, Zach and Rosie use different methods to calculate their lunchtime duration, both arriving at the correct duration of 1 hour and 10 minutes, albeit through different calculations. The lesson encourages discussion and reasoning, prompting students to consider alternative strategies for calculating time durations and to explain their reasoning for their chosen methods.
