This school year, I’ll be creating and posting 125 new ESti-Mysteries.
Throughout the school year, I’ll add new ones to this blog post – so you can find them all here.
Each time I add a new one, I’ll let blog subscribers know. If you are not subscribed to the blog, you can sign up here.
Blog subscribers will also learn about many other resources that I post throughout the school year.
Thank you for sharing these Esti-Mysteries with colleagues in your school.
Let’s spread the math joy!
