Frequently asked questions

Google Slides is what I use - How does that work?

I use these materials with Google Slides all the time.

Since they are PowerPoint materials (which I've designed to work in either PowerPoint or Google Slides) you can simply download them, then drag them from your downloads folder into your google drive... and then click to play them.

If you want you can also save them as Google Slides which is pretty nice if you want to include them in other slide decks.

Are these the same Esti-Mysteries that are on your blog?

Yes! These are exactly the same Esti-Mysteries that I have posted over the past 5 years (during the 2021-2026 school years).

Here's what is new: I have gone back through the past 5 years (file by file - it took a LONG TIME) ... and I pulled together all of the Esti-Mysteries from each level into a single file.

That way, you can have exactly the level you want all in a single download.

Will the Esti-Mysteries still be on your blog?

Yes, they will remain there. I am very proud of that work, and plan to leave them there permanently.

That is a really good option for getting Esti-Mysteries.

This sale is an opportunity to get all of the Esti-Mysteries from a certain level - all organized into that one level - in a single download.

The benefit of the sale is that you will have all of the Esti-Mysteries from your grade level all at once.

So you can save a lot of time all throughout the school year.

I purchased all the prior sets. Should I buy this one, too?

If you purchased all 5 of the prior years on my Podia store, I would NOT purchase these, since they are the same ones.

They are organized differently (by level) but they are the same ones.

Estimation Clipboard Questions

How is an Estimation Clipboard different than an Esti-Mystery?

Great Question!

While an Esti-Mystery may take 5-10 minutes, an Estimation Clipboard is much quicker.

Here is one part of an Esti-Mystery:
(Plan for about 10 minutes)

...and here is the end of an Estimation Clipboard

(Plan just a few minutes.)

What grade levels are Estimation Clipboards for?

Estimation Clipboards can be used at any grade level. The use of numbers is quick, simple, and universal.


I have used them with all ages.

They also are an excellent resource for staff meetings and family math nights!

How will I use 150 Estimation Clipboards?

You'll use them much more quickly than you expect.
I rarely use just 1 estimation clipboard. They are so quick and inviting that I almost always plan to use 2 of them back-to-back.

After I finish one like this...


Students may immediately ask for another, and I always have a 2nd one ready.

150 Estimation Clipboards

Chart options are embedded in the Esti-Mysteries!

Every Esti-Mystery (grades 1-12) has 3 versions!



1.  The Original Version of the Esti-Mystery



2.  The Embedded Chart Version



3.  The Animated Chart Version



You receive ALL the versions
so you can use the one that works best for you!



The Original, The Embedded Chart, The Animated Chart

The Original Version

This version displays the clues while students write on their own and discuss the clues with each other!

The Embedded Chart Version

The student experience is exactly the same but there is an embedded chart for the teacher to write on.

If you want a chart to display - and write on - this is a great option!

The Animated Chart Version

The chart is animated in this version.  After each clue appears, students read the clue, discuss the ideas, possibly adapt their estimate...

...and then you click and any number eliminated by that clue will be greyed out on the chart.

This version is a really powerful way to show which numbers are eliminated by which clue. 

Choose the Version that Works Best for You!
