This school year, I’ll be creating and posting 170 brand new Esti-Mysteries.  I’ll be posting a new one nearly every day for the rest of the school year – just like last year.  The purpose is the same as last year:  Sharing math joy with you all year long!

Prepare for math joy and rich math talk in your classroom as your students work with many concepts, estimation, and a sense of mystery!

May your classroom be filled with math joy and rich math talk all year long.  As always, I’ll let everyone who is subscribed to my email list know when new resources are posted.

New Estimation Clipboards can be found here.  (All Grade Levels)

Frequently Asked Questions

How to Download the Esti-Mysteries

Q:  How do I get the Esti-Mysteries?

A:  Simply click on the BLUE download link that is the name of the Esti-Mystery.

The Google Slides Question

Q:  These are PowerPoint files, but I use Google Slides.  Can I use them?

A:  Yes!  I use them in both PowerPoint and Google Slides.  After you download the PowerPoint file, make a new folder in google drive and save it into that folder.  Then click on the file (I usually right-click it) and the choose “open with” and then Google Slides.  Then just click Present.

To Receive Notifications

Q:  How can I find out when new Esti-Mysteries are posted?

A:  Simply sign-up for the mailing list on the blog, and I’ll let you know when new ones are posted.

The Clues / The Reveal

Q:  How to I get the clues to appear one by one?

Q:  How do I get the reveal to appear?

A:  Make sure the slide show is playing.  In PowerPoint, click on View Show.  In Google Slides, click on Present.  When it’s playing the clues will appear one at a time, and when you reach the reveal it will appear when you click.

The Embedded Charts

Q:  I see that some of these have charts.  Which one do I use?

A:  Each Esti-Mystery comes with 3 versions (3 options) so you can choose the one you want to use.  The first one has no chart.  The second one has a chart that is show so that you can write on it.  The third one has an animated chart that will shade in numbers that have been eliminated by the clues.  Use the one that works best for you.
