This lesson is impressive, as an aspiring math teacher the creativity and craftiness of this lesson is motivating. To whom could I attribute this lesson?

Thank you for the kind words, Joshua! I stole the Google Slides idea from Dan Meyer. The 2nd page of the warm up is from Don Steward. Finally, some of the spiraling problems are from our released state exams.

Hope that helps. Good luck with the beginnings of your career!
