# 170 New Esti-Mysteries

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)

### NEW THIS WEEK!

Wednesday, May 31, 2023

Kindergarten:  Esti-Mystery 89  –  “Noodles”

Grades 1-2:  Esti-Mystery 199.G  –  “Oodles of Noodles”

Grades 3-8:  Esti-Mystery 399.F  –  “Neon Noodles”

Grades 1-3:  Esti-Mystery 299.A  –  “Stretching”

Grades 4-12:  Esti-Mystery 469  –  “Finale”

Q:  How do I get the Esti-Mysteries?

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.

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.

1. Megan

My first graders LOVE the Esti-Mysteries! Thank you for sending them each week. Can you remind me why some Esti-Mysteries show a die and what does it represent? I think you posted about this before, but I can’t seem to find the answer. Thank you!

1. Steve Wyborney

Hi, Megan. That’s a great question! Sometimes the die has a clue, and sometimes it doesn’t. It’s always a bit of a surprise whether it holds a clue or not, and if the clue will point out or eliminate numbers. Another important way I use the die is as a size reference because sometimes it helps students to better picture the size of the objects or the container.

2. Sami b

I have to say I have done one of these every day with my class and they love it! I even started having a student a day be the teacher and walk the rest of the class through it as they are really starting to understand it. It is such a good warm up to get their minds ready for math.

1. Steve Wyborney

What a great idea!

3. Isabelle

Hi Steve!
I have been following you for years now. My students and I just love everything you create especially the esti-mysteries. Thank you so much for sharing your great work!

1. Steve Wyborney

I really appreciate this note, Isabelle!

4. Have already incorporated this into my class this year. Used the 3 Container one today and they love it as much as EstiMystery and Estimation Clipboard. It really makes them think mathematically!

1. Steve Wyborney

I’m so happy to hear this, Lisa! Thank you for sharing – and I’ll keep the materials coming!
Wishing you a great day,
Steve

5. Nelia

Thank you for your wonderful work and for sharing.

1. Steve Wyborney

It’s my pleasure!

6. Karen Gartland

Steve,
When I click on the link for the 3-container estimation routines click in the email above, it takes me to the website link with estimation clipboards. Am I doing something wrong?
Karen Gartland

1. Steve Wyborney

Hi, Karen. I may have sent the wrong link. Here is the link to the 3-container Estimation Routine. I hope you like it! https://stevewyborney.com/2022/10/the-3-container-estimation-routine/

1. Karen Gartland

Thank you so much Steve!!! We love everything you create and are so appreciative of your generosity. Although I have purchased your “class” to make my own esti–mysteries I still like using yours as well. I am looking forward to doing the three-container estimation routines with the kiddos.

1. Steve Wyborney

Thank you so much for all of this, Karen. I’ll keep the resources coming!

7. Jennifer Ablack

Hi Steve! I love your stuff! My class loves it too. Here’s my problem….only one has worked for me. I can’t to get past all the ads and I want to show it without all the extras. Any suggestions?

1. Steve Wyborney

Hi, Jennifer. I posted some new ones yesterday. If you scroll down to the “New This Week” section, you’ll find the dates and see the new one I posted today. The download links are blue.
I hope that helps. 🙂

8. Lis

Thanks so much for these. The class of 7-8 year olds I was looking after last week loved them and asked to make their own. They had heaps of fun although we have a little work to do on clues, although cute, I’m not sure Clue #2: ‘It is a lot’ would help the estimator!

1. Steve Wyborney

That’s really fun! I’m also learning to improve my clues as I go and I love to hear how they are creating their own!
