4 MAJOR UPDATES from Summer 2025. Here's a recap, but more details are in the video below.

1. Estimation 180 is back up and running. It was down (boo to 503s). NOW it has many teacher resources I think you're going to love! I explain in the video below.
2. I started the YouTube channel to house helpful videos and accompany blog posts. Please watch the video to learn more.
3. I launched andrewstadel.com to house additional resources like my blog, workshops, and other services. 
4. I'm building Estimation 180 Toolkits for grades 3-6. Learn more about the Toolkits at estimation180.com/toolkit

When I held my first free webinar this summer with math teachers to give them a preview of a Free mini course (which contains 5 essential tips form the full workshop), I received feedback from them on how to make it better. One frequent request I get is aligning Estimation 180 tasks with grade level standards. With the Estimation 180 Toolkits, I plan to honor that request. The toolkits will contain exclusive Estimation 180 tasks, downloadable files, video introductions, and video reveals related to specific math standards.

Thanks for being here. Learn more about the Estimation 180 Toolkits at estimation180.com/toolkit and share this blog post with anyone you think might be interested in these same resources.
