New Estimation Clipboards

To date, I’ve created 101 estimation clipboards – and I’m going to create more to share this month.  They are very fun and easy to use – and your student will love them!  They are also a very exciting and powerful way to build number sense.  As I create more, I will post them here.

Download the new sets of estimation clipboards and use them in your classroom to promote number sense, rich math talk, and math joy in your classroom.

Find the schedule below to see how new ones will be posted daily.

Estimation Clipboard 101


Question:  I see this is a PowerPoint file, but I use Google Slides.  Is there any way to make it work?

Answer:  Yes, it’s actually very easy to do.  In your google drive, create a new folder and name it.  Then after you download the PPT file, drag it into the google drive folder.  Then “open with” google slides.  Then just click present.

    Hello Steve, Thank you for making these. I use them all the time and I hope to finally create some of my own this year. I am having trouble finding The Esti Clipboard for Wednesday, Oct 13, and Thursday, Oct 14. They are not linked on the page. Am I missing something?

    Good morning. I love the esti-mysteries. Will you be following the same routine you did last year with different grade levels and clues?

      Yes, on November 1 I’ll be posting daily resources like last year.
