    Steve, thank you. Your resources encourage so much thinking and enthusiasm in my students. Thank you for all your hard work!

    • Steve Wyborney on April 11, 2021 at 9:07 am

      Hi, Sanja. I’m so happy I can make a contribution to your classroom that encourages rich thinking and enthusiasm.

  2. Nikki on February 3, 2021 at 12:50 pm

    Hi Steve!

    I am hoping to use the Estimation Clipboard with my students. However, when I click on the bundle nothing happes. Is this a problem on my end or are the links broken? This happens on all the bundles I try to access.

  3. Stacey Corrigan on November 22, 2020 at 9:05 am

    Hi there – I’ve seen some estimation clipboard in centimetres before now but can’t seem to find them now. Could you direct me to them please / post a link. My class love them – thank you!

  4. Cheryl Allen on September 27, 2020 at 11:29 am

    Thank you, Steve! I’m pumped about using the Estimation Clipboard! Thank you for creating and sharing this!

  5. R. Salvagna on January 3, 2020 at 10:22 am

    This is fantastic!! Would love to have the metric versions so we can use them more efficiently in Canada!

  6. Jillian on December 9, 2019 at 3:50 pm

    Hi Steve,
    I use your resources a lot and share them often in my role as numeracy coach. All students that I’ve worked with have loved Estimation Clipboard. I have converted Sets 5-8 to metric. Let me know if you would like a copy so that you can share it.

  7. Amy on September 11, 2019 at 7:10 am

    Hi Steve! I love your blog and all your free resources, thank you!!! I have used them in the past, however this year the estimation clipboard is not working properly on my end. All 4 images are showing up with one click and the reveals aren’t coming up. Any feedback or tips would be greatly appreciated.

    • Steve Wyborney on September 13, 2019 at 6:24 am

      Hi, Amy. The key is to make sure the slide show is playing. In PowerPoint, go to view show and play it from there – or in Google Slides make sure to click on Present.

  8. Kelly-Ann Cumming on May 24, 2019 at 4:11 am

    I just started using your 20 Days if Number Sense with my Year 2 class here in Metford, Australia! My kids love it sooo much! They don’t want me to stop! They have even asked if they can take their own mystery pictures at home and send them in for the class to estimate!! Thank you

    Hi Steve,
    I am a huge believer and fan of your resources and my middle school students are fans as well. I can not thank you enough for providing all of these powerful tools for me to share with my students in an intervention setting as well as for me to share through modeling with the teachers in my building who I co-teach math with. The rich math conversation opportunities are so valuable and provide such insight into the student thinking. Recently, while introducing the estimation clip board lesson with my 6th grade intervention group and discussing the 4th slide before the reveal a student shared his thinking and how he connected it to the splat lessons. He shared how it was like covering (splat!) what was missing in the cup with gems to figure out how many remained. Great thinking, connecting and sharing for this student. Thank you for making it so easy for me to use the google slides to engage my students in rich math discussion while I am teaching middle school math, a craft I so love.

    Hi! I’ve been гeading your site for some timе now аnd ffinally gott the couraɡe to go ahead
    and ɡive yyou a shout out from Kingwood Ƭexas!
    Justt wanted to mention keep up thee good work!

  12. Joanne Indovina-Duncan on October 12, 2018 at 10:59 pm

    Thank you so much for these resources.

    Would love to see the cm conversion for your measurement estimation clipboard activities 😉

  13. Kelly on May 16, 2018 at 8:23 pm

    Hi Steve,

    I cannot thank you enough for all of your WONDERFUL resources!! I am a teacher in Ontario, Canada and we have been trying really hard to develop our staff’s use of visuals in mathematics. I have recommended your resources many, many times this year, and use them regularly in my own grade 4 classroom.

    It is hard to even describe my students’ excitement and involvement when we do an Estimation Clipboard activity…you would swear they were watching a nail-biting hockey game or something. I always make sure to close my door as I know the cheers and hooplah will be ear-splitting. It is my goal during the last few weeks of school to have students take some photographs of their own estimation items to make our own estimation clipboard slides.

    Thank you so very much for your hard work and expertise! I hope you know how widespread your influence is!!

    With gratitude,


  14. Tyler Flock on April 26, 2018 at 9:35 am

    This is a great resource! I was hoping that Steve would be at the Oregon RTI conference this week to have more discussion about how the estimation clipboard is used in the classroom!

    • on May 2, 2018 at 8:56 pm

      Hi Tyler,

      I’m hoping to make it to the 2019 conference. I have posted the first 20 estimation clipboard sets and am hoping to post the other 20 soon

  15. Maria Rose on April 23, 2018 at 10:01 am

    This is SOOOO amazing. I teach a class called Math Lab, where I work with kids who have a mindset block about their ability in math, along with real issues of holes in their understanding. I’ve tried to use Estimation 180, which is a good site, but my kids just struggle to use it because they lack the confidence in their reasoning ability. These slides COMPLETELY support them in learning how to depend on their own reasoning AND being able to argue based on the displayed data. I am SOOOOOO excited by these! Thank you!

    • on May 2, 2018 at 8:59 pm

      Hi Maria,

      I can hear the enthusiasm in your words. Thank you for sharing! I’ll keep posting more of them. It’s fun to share some of my favorite activities that lead to rich thinking. It’s even more fun to hear this level of enthusiasm. Here come some more…

  16. Julie on April 22, 2018 at 11:51 pm


    Once again, an amazing piece of work and it is fabulous! I was wondering if you might be planning any using metric measurement? I am a teacher overseas in and international school and use your site regularly for your other items, but just wondered if this might be a possibility at some pont?
    Again, thanks so much!

    • on May 2, 2018 at 9:00 pm

      Thank you, Julie. Yes, metric measurement is in the works. I’m excited to post it soon!

  17. Michelle Rea on April 22, 2018 at 11:11 am

    This is fantastic, Steve! I’m a big fan of using your resources in my classroom which is located here in Australia.
    My question: Could you please adapt your ‘length of string ‘ estimation series with metric measurements?

    • on May 2, 2018 at 9:01 pm

      Yes, I’ll be adding metric measurement soon. Thank you for the kind words!

  18. Jane Paulin on April 22, 2018 at 9:56 am

    Thank you so much! Would you mind if I make a copy and change the measurements to centimeters? This looks like a wonderful way to work on metric measurement benchmarks! Makes me think about doing this with capacity as well (perhaps you have that already planned….) Can’t wait for the rest of these! Thank you so much for sharing. I have learned much from your blog and have purchased your book for my summer reading!

    • on May 2, 2018 at 9:02 pm

      Hi Jane,

      Please feel free. I’ll be adding some new ones that are specific to metric measurement soon. I hope you enjoy reading The Writing on the Classroom Wall.

  19. Kali Kopka on April 22, 2018 at 7:24 am

    Thank you for another engaging and well-designed resource! Estimation is something my students often struggle with so I am really looking forward to doing this with them.

    • on May 2, 2018 at 9:03 pm

      I’d love to hear how it goes, Kali!

  20. Leonie on April 21, 2018 at 6:33 pm

    You are so great to share these. They are so creative and well done. You have always focused on the things that students need more practice with. When working through the ‘cube conversations’ I tried a few times to stop after a few and the kids were saying please can we do one more and I love maths. Thanks for all you do.

    • on May 2, 2018 at 9:04 pm

      Hi Leonie,
      Thank you for sharing this. I hope you have had some insightful classroom conversations with The Estimation Clipboard.

  21. Roslyn Wikoff on April 21, 2018 at 10:41 am

    Wow! Love these! Looking for to trying these out with my second graders!

    • on May 2, 2018 at 9:05 pm

      I would love to hear how it goes, Roslyn!

  22. Tara Flint on April 21, 2018 at 5:37 am

    Can’t wait to try this!!!
    Thank you!!!

  23. Heidi McPartland on April 18, 2018 at 9:09 pm

    These are awesome and timely for my classroom! Thank you!

    • on May 2, 2018 at 9:09 pm

      My pleasure!

  24. Donna Ship on April 18, 2018 at 1:32 pm

    Hi Steve,
    This is so great.
    Do you have a metric version for Canadians?
    Thank you!

    • on May 2, 2018 at 9:10 pm

      Yes, there are metric sets coming soon! I’m excited about them!

  25. Sheila Saeger on April 18, 2018 at 6:14 am

    Wow! This is WONDERFUL!!!! I have so few resources for measurement estimation so far (after teaching for several years!!!) and this is perfect! It couldn’t have appeared at a better time, either, as we are in the middle of a measurement unit. 😀 Thank you so much!

    • on May 2, 2018 at 9:10 pm

      Sheila, I’m glad the timing worked out so well. I’ll keep posting more.

  26. Sarah Roach on April 18, 2018 at 6:09 am

    Thank you so much! Looking forward to the rest of the lessons. Will be sharing this with teachers today.

    • on May 2, 2018 at 9:11 pm

      Sarah, thanks for sharing these lessons with others. I hope it went well!

  27. Sandy Mueller on April 18, 2018 at 3:29 am

    You’ve done it again! My teachers and students will love these! Thanks for another great resource to build that number sense!

  28. Julie Small on April 17, 2018 at 9:45 pm

    This is an amazing resource! Thanks so much.

    • on April 17, 2018 at 10:06 pm

      Thank you, Julie! I really appreciate it and would love to hear about your experiences with it!

  29. Nic Petty on April 17, 2018 at 9:31 pm

    Hi Steve
    Great work as always.
    One problem – the rest of the world doesn’t use inches. Any chance you could provide alternatives with centimetres or millimetres. I’d be happy to do the conversions for you and you could post them here.

    • on May 2, 2018 at 9:12 pm

      Hi, Nic. Yes a version with cm is coming soon.

    • Kelly on May 16, 2018 at 8:17 pm

      I was hoping for metric units as well and would very much appreciate that for use in classrooms in Canada! 🙂
