This school year, I’m creating 150 brand new Esti-Mysteries. I’ll be posting a new one nearly every day for the rest of the school year – just like last year. This is my way of sharing math joy with you all year long! Prepare for math joy and rich math talk in your classroom as your students work with many concepts, estimation, and a sense of mystery!
For more information, see the FAQs at the bottom of this post.
