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 added 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 can read the clue, discuss the ideas, possibly adapt their estimate...

...and then you can 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.

Every beginning level (Kindergarten) Esti-Mystery has an animated chart.


The chart is built in - and it automatically eliminates numbers after every clue.

You can show the clue and have your students discuss the ideas...

...then click to show which numbers were eliminated by that clue.

Do you recognize this moment?

You may have seen this...

...right before you heard the cheering.





You'll also receive 36 Estimation Clipboards!



Estimation Clipboards can be used at any grade level.

Estimation + Number Sense + Math Joy!

Estimation Clipboards are a very simple - and very powerful - way for students to experience invitations to estimate.
