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!
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!

If you blog, this might sound familiar: Partway through a post, but not yet finished. That’s me, right now. I’m slugging it out, slogging through the middle. The “quicksand middle” is how I’ve come to think of it. The more I struggle, the more difficult it seems to be. Oddly, I have everything I…Read More
