- 1. Lesson 1
- 5. The 12-hour time format divides a 24- hour day into two equal cycles or periods. The first cycle is AM, which means ante meridiem (before midday) in Latin, while the second cycle is PM, which means post meridiem (after midday).
- 6. Ante Meridiem (a.m.) and Post Meridiem (p.m.) is used in a 12-hour clock at the end to denote whether the time is in the morning or afternoon. Ante meridiem (a.m.) – is used after 12 midnight and before 12 noon. - (12:01 a.m. – 11:59 a.m.) Post meridiem (p.m.) – is used after 12 noon and before 12 midnight. - (12:01 p.m. – 11:59 p.m.)
- 7. Activity AM or PM? Eating breakfast Taking a bath before going to school Praying before sleeping at night Playing toys with siblings/friends after school Doing your homework after school Eating dinner Is it AM or PM? As a Grade 5 pupil, when do you usually do the following activities? The students will use the paper clock with a.m. or p.m. labels to use the class what time in the 12-hour clock they perform the following activities.
- 8. When using AM and PM, the 12-hour time format is employed. There are two equal cycles or periods of 12 hours in a day. The 1st 12-hour period/cycle refers to AM, which is from 12:00 AM to 11:59 AM, while the 2nd 12-hour period/cycle refers to PM, which is from 12:00 PM to 11:59 PM.
- 9. Understanding the 12-hour time format including the appropriate use of AM and PM is essential. This can prevent misunderstandings and confusion in communication and improve our ability to manage our schedules. For instance, if you invite your classmates to your birthday party at 8:00, they need to know if it is AM or PM; otherwise, they might get confused. Another was meeting a friend I had not seen for a long time at 7:00, but she came at 7:00 AM when I meant 7:00 PM.
