I’ll be posting 110 New Esti-Mysteries this school year. If you are subscribed to the blog, I’ll let you know each time a new one is posted.
Leaping Numbers Season 3 Begins on February 2, 2026! To learn more watch this video.
How to Use Esti-Mysteries
- Use the blue links below to download the Esti-Mystery. Each one is a PowerPoint file. If you use Google Slides, just save the PowerPoint file into your google drive. Then open it with Google Slides.
- When you open the PowerPoint (or Google Slides) file you will see several slides. That’s because there are 3 choices with each Esti-Mystery.
- No Chart Version – Start on Slide 2
- A Version with a Chart to Write On – Start on Slide 8
- An Animated Chart – Start on Slide 14. (This is the version I use.)
- Then be sure to play the slide show.
- In PowerPoint: After you click on the slide you want to start on, click: Slide Show, then click: From Current Slide.
- In Google Slides: After you click on the slide you want to start on, click: PRESENT
