    My kindergarteners just love the activities from your site and I am seeing their math skills surpassing students from previous years since I started using them. We do Splat, Estimysteries, Estimation Clip Board, and today we did the mazes. They actually got so excited after an estimystery final answer was revealed that the Principal came in and told them to be quieter. lol!

      I love reading about this enthusiasm and how well the students are doing! Thanks for sharing, Lisa!

    I love using esti-mysteries in my Gifted class. Will you be creating new ones for this school year?

    • Steve Wyborney on September 25, 2023 at 5:54 pm

      Yes, I’ll begin posting new ones about the 2nd week of October.

    Hello! I am brand new to using esti-mysteries. I am hoping to understand the “scope and sequence”. I was able to find Kindergarten up to number 8 but then when i click on part 2 it starts on Esti-mystery number 16 – am I missing something? Also, is there a link for google slides or only powerpoint?

      Hi, Pamela. All Esti-Mysteries should work in Google Slides. The file is a PowerPoint file, but if you save it into your google drive and then open it from there (it will essentially open with Google Slides) then it will work. I’ve chosen animations that work in either Slides or PPT. The reason there are so many levels at once is that I wrote daily materials that reached every level starting back in 2020 and the months that followed when we all faced the challenges of distance learning. I posted something for each grade span throughout the week. Now it looks like a combination of so many things. The Part 1… Part 4 is a combination of materials. Since that time I wrote 150 Esti-Mysteries and am currently writing 170 Esti-Mysteries. The easiest way to navigate those is to find the level you are looking for and to just download those PPTs. As far as a scope and sequence, as I progress through the year, they become more challenging. So the early kindergarten ones (in 150 EM and 170 EM) are much simpler (and have lower numbers) than the ones that appear later in the year. I hope that all helps. Here is the link to 150 Esti-Mysteries from last year: Here is the link to 170 Esti-Mysteries which I’m currently writing (during the 2022-2023 year)

    I love using your resources and my students do too! Thank you for all your efforts and for being so willing to share! I just discovered the book you wrote – The Writing on the Classroom Wall. It looks like a book I NEED. 🙂 I am excited to be able to read it and all the “slow bolts of lightning” you have experienced thus far.

    Thank you for providing Esti-mysteries. I love hearing students and adults cheer as they continue to refine their estimation!

      Hi, Kristine. Certainly, it’s my pleasure to create and share them, especially when I hear about students and adults cheering! I’m so grateful for this comment.
