Time - Start and end times - Presentation

In the series of lessons focused on time, students in Year 6 are introduced to calculating start and end times for various events, given the duration. The lesson begins with a review of basic time units, asking students to recall how many minutes are in an hour. This foundational knowledge is essential as they move on to more complex tasks involving the manipulation of time. Students are encouraged to discuss and engage with the concept of time by practicing the placement of hands on a clock face to determine the start and end times of activities such as playtime and lessons. For instance, they are challenged with scenarios like determining the end time of playtime that starts at five past ten and lasts 20 minutes or finding the start time of a fifty-minute maths lesson that finishes at 10:15.

Further activities involve using a number line to calculate time, which provides a visual method for students to understand the addition and subtraction of minutes and hours. They are tasked with figuring out the end time of a 25-minute lesson beginning at 2:15 p.m. or the start time of a journey that lasts 1 hour and 10 minutes and ends at 4 o'clock. Students also compare different activities to determine which ends later, such as gymnastics that starts at 15:30 and lasts for 1 hour and 15 minutes versus football beginning at 16:05 and lasting 45 minutes. The lesson includes reasoning exercises where students must decide who is correct in a scenario where one student suggests school ends at 3:15 p.m. while another says 2:75, prompting a discussion about the correct way to add time. The lessons culminate in independent work where students complete tables with missing start or end times and solve problems using number lines, fostering their ability to work autonomously and reinforcing their understanding of time management.
