Max Maths, Year 5, Learn together, The 24-hour clock (2)

In the 'Max Maths, Year 5' curriculum, students are introduced to the concept of the 24-hour clock, which is an essential skill for telling time accurately and understanding daily schedules. The lesson focuses on comparing the conventional 12-hour clock format, which uses 'a.m.' and 'p.m.' to distinguish between morning and afternoon times, to the 24-hour clock format that is commonly used in timetables and digital devices. For example, 4.00 a.m., commonly spoken as "4 o'clock," is written as 04:00 or spoken as "4 hundred hours" in the 24-hour format. Similarly, an afternoon time like 6.00 p.m., or "6 o'clock" in the 12-hour system, is represented as 18:00 and referred to as "18 hundred hours" in the 24-hour system.

The lesson provides a clear table that helps students to visualize and practice the conversion between the two time formats. It includes various examples such as 9.30 a.m. being shown as 09:30 in the 24-hour clock, spoken as "zero nine thirty," and 9.00 p.m. translating to 21:00, or "21 hundred hours." The table also clarifies that 'a.m.' indicates times before noon, while 'p.m.' is used for times after noon. To further aid understanding, the lesson includes a sequence that shows the progression of times throughout the day, starting from 00:00, which is midnight, up to 11:00 a.m., just before noon. This provides a comprehensive guide for students to learn and confidently use the 24-hour clock in everyday situations.
