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 the upcoming Estimation 180 Toolkits. Join the Waitlist below.
4. I'm preparing a workshop and Estimation 180 Toolkits for grades 3-6. Watch the video until the end to learn more about my special offer and join the waitlist!

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 do 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. I hope you join one of the waitlists above and share this blog post with anyone you think might be interested in these same resources.
