Some of you may know Cliff Mass as the Atmospheric Sciences Professor at UW who does the forecasts on KUOW. He has also taken a deep interest in the math taught at K-12 (as he is an end user of the students and he had kids in SPS). He has a weather blog but he took time to write a long thread about math. He says a lot of interesting things and has a great quiz which I confess I failed. His point on the quiz, though, is that it shouldn't be difficult for students who just graduated from high school and got into UW.
There's a link to the quiz at his blog.
