Time FAQ

On a clock there are two hands. The $\text{hour hand}$‍ is the shorter hand. The $\text{minute hand}$‍ is the longer hand.

First, we need to look at the hour hand. The hour hand is between $1$‍ and $2$‍, so it is after $1$‍ o'clock but not yet $2$‍ o'clock.

So, the hour is $1$‍. Next, we look at the minute hand.

The minute hand starts pointing straight up for $0$‍ minutes.

When counting minutes, the distance between each tick mark represents $1$‍ minute.

Each number on the clock represents $5$‍ minutes, with a total of $60$‍ minutes in each hour.

If we unroll a clock, it becomes a number line! We can set up a number line to represent minutes in an hour. Then, we can mark the start time and end time of an event, and count the number of minutes between the two marks.

To find out how many minutes are between $9:18$‍ to $9:57$‍, we can find the distance from $9:18$‍ to $9:57$‍.

Knowing how to calculate elapsed time helps us understand how long it takes to do certain things, like driving to a new place or completing a task.

Time is an important part of our lives, so this unit has many real-world applications. We can use what we learned to keep appointments, plan our day, and understand how long things take.
