    Hi Steve. My class LOVES these 3-container estimation activities! I love how it takes the estimation clipboard to the next level! I’m just wondering if you will be posting more? Thanks so much!

    There is definitely a problem because there is no link to download the 5/10 3 containers estimation problem. Ana

      Hi, Ana. Can you try again now? Even though I could see it here, I think it took a must have taken a bit for the cache to clear this time.

      Hi, Loraine. Thank you for the kind words, and greetings from Oregon in the U.S. where we are just entering into the fall and anticipating winter. I’m so glad to hear how much your student love them.

    Hi Steve,
    I also can’t access the 3 container estimation for Oct 5.
    Thanks for your work, I live using your resources

  6. Jennifer Gillig on October 3, 2022 at 7:15 am

    Where is the link to use this?

    • Steve Wyborney on October 5, 2022 at 4:31 pm

      Hi, Jennifer. The download link is the blue link just below where it says Monday, October 3.

  7. Melinda Watkins on October 3, 2022 at 4:30 am

    I’m having trouble opening my download as well. I do not wish to use the 3rd party search engine and am hoping there is another way

  8. Cee on October 2, 2022 at 9:19 pm

    So excited. You are amazing and I am greatly appreciative of your dedication and sharing.

      Thanks, Cee!

    I would really like to get this resource. Maybe I am having a slow Sunday, but I don’t understand how to download it. I have watched the youtube video and I have looked at the “Downloadables” page. Where is the link to download? Thank you for putting this together!

    • Steve Wyborney on October 2, 2022 at 10:18 am

      Hi, Jaime. I cleared the cache so it should be showing up now. Thank you so much for taking a look at it!
