    Dear Mr. Avery’s class,

    Thanks for that great video about how to solve elapsed time problems. This will be a big help to my third graders when we get into elapsed time next month. I have never tried this approach, but it is very similar to our number-line subtraction strategy so it will make a lot of sense to my class.

    Thanks for teaching a teacher!

    Dear Mr. Avery,

    It is our summer holidays and I thought I would pop in. How I enjoyed the video. It is a great way to solve such problems, so I did a bit of learning. We use such empty number lines for adding and subtracting so I was familiar with it, but I particulary enjoyed this video. Well done Amanda and Marshall.

  9. Mr. Avery says:

    Dear Class,

    I’m really glad that this video helped you with elapsed time. Marshall and Amanda did such a wonderful job of explaining it. I’m looking forward to all of you creating new math videos to help us understand other math concepts.

    Keep up the great work!

    Your Teacher,
    Mr. Avery

  10. Jenna K. says:

    Dear Mr. Avery,
    Amanda and Marshall did a wonderful job on the elapsed time problem. This elapsed time problem will help me in the future. I might need this elapsed time problem to figure out how to find how many hours passed in the amount of time in 7 days. The multiplication problem would be twenty-four times seven and that equals 168. I hope these elapsed time problems will help me. Keep up the good work.

  12. Marshall Smith says:

    Dear Mr. Avery,
    Do you think Amanda and I did a good job? Well, I hope you did because it was very hard to keep looking at the camera. I also think that introduction and ending thing was cool.

    Sincerely,
    Marshall

  13. mrsdelgado says:

    Hello Marshall and Amanda! I am so impressed with your elapsed time video. Thank you for sharing it! I am going to show it to my third graders so they can learn your method as we study elapsed time ourselves. Keep up the great work Mr. Avery’s class! Way to go!

    Sincerely,
    Mrs. Delgado

  15. Ethan P. (Amanda's other favorite cousin) says:

    Amanda,

    I wish that I had a video like this to watch when I was learning math. Nice job explaing how you figure out the amount of time that elapsed. I think it will help me. Ben and I are practicing doing it the way you guys showed us. It’s a lot easier your way. I liked your video! Have a good day.

  21. Susan says:

    Amanda, Marshall and Mr. Avery,

    Thank you so much for posting The Elapsed Time Video!
    It has helped me so much!!
    I had problems learning math in 3rd and 4th grade-it has held me back from doing a lot of things throughout my life. I am now 55 and just beginning to understand elapsed time…Thanks to your
    FANTASTIC explanation! I have one request that would help me and possibly others too. Would you please post a sample page of some problems with the answers worked out in a PDF format? I would appreciate that greatly. Amanda and Marshall…you are both so gifted in teaching that I am sure you will excel in whatever path you choose to pursue in life. Enjoy your studies…it really is the key to open the door to anywhere!

    Thank you again,
    Susan

  22. Sue Downing says:

    Very creative and impressive video. It gave me an idea for a laminated fill-in-the-blanks timeline to help students visualize how to create their own. May I link to your webpage in a blog post about elapsed time?

  23. Mrs. H in NC says:

    Dear Amanda and Marshall,
    This is my third year teaching elapsed time to a group of third graders. Every year I “research” ways to teach elapsed time in a way that students will understand. I FOUND IT! Thank you so much for making this video. I can’t wait to share it with my students tomorrow morning!

    Thanks so much for providing and explaining a strategy that I can use for years to come.

    Mrs. H.

  24. Billie Jean says:

    Thank you so much for posting this on-line! We have a fourth grader and two third graders in our family this year. The third greaders picked up elapsed time in a snap but the fourth grader was so confused and getting very frustrated, in part because it didn’t make sense to him while his two sisters thought it was sooooo easy! After finding this method he has relaxed and feels comfortable doing elapsed time problems. In fact, when I came down this morning he was sitting at the kitchen table doing more of them just for fun because now it makes sense and he is enjoying the math. This is a really great approach and we appreciate that you have made it availble to others like this!

  25. Teri Rushford says:

    Thank you so much! We are always looking for another way to help our students!

  26. Mr Jackson says:

    Hi Guys! Thank you so much for this! I am a new teacher in the UK and so I am still learning about how to teach children these things. I can honestly say this video is perfect!!! It taught me perfectly and I think it will be great to show it to my class when we do this.

    Thanks guys and girls.

    Mr Jackson

  27. Felicity Ross says:

    I love this video! I have been looking for a way to teach elapsed time to my last few students who still aren’t getting it. I hope this will work for them. Thank you!!!

  28. HelloMissWright says:

    This is great! I’m going to post this to my classroom website to help my kiddos learn elapsed time. This is also a great examples of what I’ve been trying to get my kiddos to do-make their own learning videos explaining their math skills! Great job!

    • Mr. Avery says:

      Hi Miss Wright,

      We’re so glad that you’re going to add it to your website! We’re thrilled that it will help.

      If you make any math videos, we’d love to see them. We’d also love for you to add them to the Student Made Math Movies.

      Sincerely,
      Mr. Avery’s Class

  29. Marni Singer says:

    Hi Mr. Avery!

    Thank you so much to you and your students for that great video! I’m going to teach my students this strategy next week. What do you do if the minutes add up to more than 60?

    Thanks!

    • Mr. Avery says:

      Hi Marni,

      If the minutes add up to more than 60 we talk about how to convert it into hours. We add our hour to the total hours in the center and then use our leftover minutes as our minute total. I hope this strategy helps your students!

      Sincerely,
      Mr. Avery

      • Marni Singer says:

        Thanks Mr. Avery!

        Did you also use this strategy to figure out beginning time when end time and duration were given, or to figure out end time when beginning time and duration were given?

        Marni

        • Mr. Avery says:

          Hi Marni,

          We didn’t but you could definitely use this for that as well. You might have to make a few slight adjustments with it but I think it could work well. If you try it, I’d love to hear how it goes!

          Sincerely,
          Mr. Avery

  30. Ms. O'Regan's Class says:

    Thanks we found this video really helpful! From a class in Canada.

  31. Mrs. Conner says:

    I love this! I’m trying it with my students today!

  32. Ms. Cherry says:

    Thank you for sharing this. I’ve been searching for a concept that was logical and easy to understand. My children are schooled at home and we’ve used the K12 and PA Cyber curriculums and this is the clearest way I’ve seen elapsed time explained. It can be a rather tricky concept for young learners to grasp, but you’ve made it simple. Thank you again.

  33. Mr. Ostrowski says:

    Thanks, Mr. Avery’s class! Our 3rd grade class watched this video to help them understand how to use an empty number line. They loved it! Now, they want to try more and more elapsed time problems.
