170 New Esti-Mysteries

This school year, I’ll be creating and posting 170 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. The purpose is the same as last year: Sharing math joy with you all year long!

New Estimation Clipboards

To date, I’ve created 101 estimation clipboards. They are very fun and easy to use – and your student will love them! They are also a very exciting and powerful way to build number sense. As I create more, I will post them here.


Welcome to Splat!  You are only moments away from a VERY POWERFUL, highly interactive number sense strategy that can be used at any grade level!

This post includes 50 (fifty!) free, downloadable PowerPoint math lessons!
