Introducing Esti-Mysteries! Each image invites students to wonder what number is represented by the image. As you click through the each Esti-Mystery, clues will appear that will allow the students to use math concepts to narrow the set of possibilities to a small set of numbers. In the end, the students will need to call upon their estimation skills to solve the mystery and find the missing number.

NOTE: In addition, to these original Esti-Mysteries, you may also want to visit the brand new post 51 Esti-Mysteries.

Here is an example:

Download the Esti-Mysteries, try them in your class, and let me know about your experience.

Update: Here are 4 Printable Esti-Mystery Charts you may enjoy using with Esti-Mysteries.

Update: Here is the Full Set of Esti-Mystery Clues (without images) to allow you to browse through the Esti-Mystery Concepts.

A Mathemagician's Game for Making Ten - Math Coach's Corner

# data[].attributes.attachment_link.description
When I was a campus-based math instructional coach, my office was across from the 2nd Grade pod. One year, one of the teachers had a student who benefitted from leaving the classroom for brief periods of time, so it was not unusual for him to "run errands" that required him coming to my office.
