Max Maths, Year 5, Learn together, The 24-hour clock (3)

In Max Maths for Year 5, students explore the concept of time, focusing on understanding the 24-hour clock. Han, a character in the lesson, observes that times in the morning (a.m.) appear identical on both the 12-hour and 24-hour clocks. For example, 9:00 a.m. in the 12-hour format is written as 09:00 in the 24-hour format. This is because the morning hours do not require any conversion or alteration when transitioning from the 12-hour clock to the 24-hour clock.

The lesson then delves into converting afternoon times (p.m.) from the 12-hour clock to the 24-hour clock. Han notes that to find the 24-hour clock time for p.m. hours, one simply adds 12 to the hour number from the 12-hour clock. For instance, 2:00 p.m. becomes 14:00 in the 24-hour format, as adding 12 to 2 gives us 14. The lesson provides a clear sequence of conversions from 12:00 p.m. through to 11:00 p.m., showing how each hour in the afternoon and evening corresponds to the 24-hour clock, with hours ranging from 13:00 to 23:00. For further practice and reinforcement of these concepts, students are directed to workbook pages 125 to 130.
