In this lesson, children learn why times such as "half past 5" can also be stated as 5:30 -- using hours AND minutes.
In the previous lesson on telling time, we only used the hour hand. Now we introduce the minute hand. I show how the minute hand travels one full round (60 minutes) while the hour hand goes from one hour to the next, such as from 4 to 5 on the clock face. This full round is 60 minutes, and so half an hour is 30 minutes. That is why, for example, half past 4 is also 4 hours 30 minutes.
We practice telling time (whole hours and half hours) in these two ways: either using the "o'clock" / "half past", or stating the hours and minutes. We also figure out what time it will be half an hour later.
This lesson is meant for 1st grade math.
