The Estimation Clipboard is a set of 40 lessons that each include 4 highly similar images.  Each image provides an invitation to estimate.  Then as new images are introduced, the students’ context and intrigue will grow – and so will their excitement.

Jennifer Barker recently wrote about her experience with The Estimation Clipboard in her post Why you should consider using Estimation Clipboard!

Watch the video, download the lessons, and try The Estimation Clipboard in your class.  You may be very surprised by what is about to happen…

  1. 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.

  2. Thank you so much for these resources.

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

  3. 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!

    1. 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

  4. 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!

    1. 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…

  5. Hello,

    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!

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

  6. 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?

  7. 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!

    1. 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.

  8. 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.

  9. 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.

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

  10. 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!

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

  12. 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.
