The Numbering System Enters the Thousands!

Long-Time Esti-Mystery Fans will notice that the numbering system looks a little different now.  The files are now numbered in the thousands!  So, what happened?

 

When I started creating daily Esti-Mysteries, you might remember that it was a very difficult time for all of us around the world, and I made a promise to create a new resource for my blog readers (nearly) every day of the school year.  I emailed every day with a new resources and let you know “I’m sticking with you every day!” From that time on, I created a lot of Esti-Mysteries, at every level – and I kept creating the next year… and the year after that.  And the numbers grew…

When I started, the numbering system didn’t seem like it would ever run out of room.

 

The 100 Level Esti-Mysteries were for grades 1-2, and they had file names like this:  100, 101, 102,  …  145, 146, 147 …

 

The 200 Level Esti-Mysteries (for grades 1-3) had file names like this:  200, 201, 202,  …

 

That all worked fine until…

That all worked fine until the Esti-Mysteries reached numbers like this…   196, 197, 198, 199 …   ???

 

At that point, I realized the Esti-Mystery after 199 couldn’t be numbered 200, because that was already used at a different level.  So, this year I continued the numbering system with 4-digits.

They simply begin with the level number in the thousands place.

    These are wonderful resources and I have used them frequently. Thank you for all your hard work! I’m searching for holiday themed esti-mysteries. I know they must exist, but I can’t find them. Can you point me in the right direction? Thanks!!

      Hi, Lindsay. Probably the closest match, as I haven’t written holiday specific ones would be if you scroll down to February 7 on this page where there are winter stocking hats.
      https://stevewyborney.com/2022/10/170-new-esti-mysteries/

      I hope that helps.

      All my best,
      Steve
