Reflection: Rigor Unit Assessment on Quadratic Functions - Section 1: Assessment

This year, I prepared a select group of 8th graders to take the first-ever Common Core-aligned Algebra I exam.  One of the new tasks was to not only use the quadratic formula, but to DERIVE it.  It was quite fun, and we used a story I found on the Internet that my kids actually LOVED to memorize it (in addition to deriving it).

A negative boy couldn't decide whether or not to go to a radical party.  Being square, he decided NOT to go... and missed out on 4 awesome chicks.  And the party wasn't "over" until 2am.

Get it? :)

See the attached student samples in the resource section for more.
