We just wrapped up our elapsed time unit and let me just say….WHEW! It was fun but it was a challenge. Partly because so many of my third graders came to me struggling to even tell time. #yikes
Tips to introduce teaching elapsed time:
I began by giving my kids a pre-assessment to determine if they even knew how to tell time. I was blown away by how many students couldn’t not correctly write the correct hour. They understood how to find the minute hand, but when the minute had was past 30 minutes and the hour hand gets close to the next hour—so many of my kids were adding an hour because it was “closer”.
Here is the template that I used:
Telling Time Teaching Tip:
Teaching Elapsed Time:
Now that we have FINALLY (hopefully) mastered how to tell time, we can now start on elapsed time.
In my little opinion, teaching elapsed time on a number line makes the most sense. Sometimes, the kids get confused on the charts. We started with a number line first and the charts second. After they learned both options, they can choose which one is easier for them.
Elapsed time trick: A trick that helps my kids with elapsed time was to break apart the elapsed time into manageable benchmark times. Ask your kids to look at the elapsed time and break it apart by hours, 10 minutes, 5 minutes, and 1 minute. Sure they can break it apart by 30 minutes, BUT, when the time is 12:45 and they are trying to add 30 minutes to that, there’s a higher chance they end up messing up the calculations.
Take a look:
Ask the kids to decompose the elapsed time using the benchmark times mentioned above.
As the kids added the times, they circled them to remind themselves that they have already added the numbers. Do you see how I added the 5 minutes before the 10 minutes?
This is because this made more sense when using ‘friendly numbers’
Practice elapsed time to strengthen understanding
I love it when my kids can practice in a fun way! Have you heard of dry erase pockets? I use them for everything! Check out how I use them in a blog post here.

I have a set of these write on wipe off math centers. Click the image above or here to see them.
I love integrating {QR Codes} in the classroom! It’s such an excellent way for the kids to check their work and at the same time I am able pull {small groups} without the hassle of kids constantly coming up to me!
Well—they still come up at times lol, but not at a crazy rate 😅
