When we want to keep track of time accurately, we have some awesome tools to help us! Here’s a simple list of the most common ones:

1. Clocks: You see clocks everywhere!

   • There are two main types:
     • Analog clocks, which have hands that move to show the hours and minutes.
     • Digital clocks, which show time with numbers.

2. Stopwatches: These are perfect for timing events, like races or experiments!

   • Stopwatches can count time very precisely, down to the second or even the millisecond.

3. Timers: Timers are super useful for countdowns.

   • You can set a timer for a specific time, like 10 minutes to study.
   • The timer will beep when the time is up!

Now, to figure out how long something lasts, we usually subtract the start time from the end time. Here’s an example with a movie:

• Start time: 3:15 PM
• End time: 5:00 PM
• To find out how long it is:
  • 5:00 PM minus 3:15 PM equals 1 hour and 45 minutes.

By using these tools and methods, we can get better at managing our time!
