What is the Meaning of AM and PM in Time? Aren't clocks useful? They help you tell time! Whether you need to understand how much time is needed for you to complete your homework, or how much time is needed for you to finish lunch, being able to tell time is very important. When we are talking about what time of the day it is, we usually say its 3 pm or 8 am. But do you ever wonder what this am and pm means? Let's find out! Today, the clocks that we use divide the day into 12 hour time increments. Why is that? Because the number of hours in a day is 24 and thus, can be divided further into 12 hours. Isn't that odd? Because our clocks show time enough only for one of the 12-hour period. Hence, to solve this problem, two portions of 12 hours are shown on the analog by using the AM and PM suffixes. The word AM. is Latin for Ante Meridiem, which means before noon. The term PM is Latin for Post Meridieum, which means after noon. This is how both the 12-hour increments are displayed in the same analog. This selection of lessons and worksheets helps students learn how to breakdown and make sense of story based math problems that include an aspect of time within them.
