This one will be a two-fer as these standards are generally covered in Geometry (rather than Algebra).
Lots of triangle material here. Pythagorean Theorem is listed in two of the score ranges, and after the session the Global Math Department had on it a few months ago, even I learned something. I've got to come up with a way to share some of those insights with my students.
For my students, tackle this Activity. There are 5 parts, try each one and don't give up until you understand the theorem and can apply it to solve problems.
