Modeling: A Mathematical Practice and a Content Standard?

Have you ever thought about the fact that “modeling” in the Common Core is not only in the Standards for Mathematical Practice, but also is a content standard? I have to admit that I hadn’t really thought much about it until a colleague asked me how the two things differed. I immediately started researching to … Continue Reading ››

Common Core Aligned! Nice new cover.

I’m just back from the NCSM and NCTM national conferences in Indianapolis.  I have nothing but kind words for the city and venues for the conferences.  It is a wonderful location for a conference; additionally, I highly recommend the haggis at MacNiven’s Restaurant and Bar on Massachusetts Ave.Continue Reading ››

Dr. Thornburg bases his reasoning on last month’s discovery by NASA that a microorganism living in Mono Lake uses arsenic rather than phosphorous to construct its DNA. He is entirely right … Continue Reading ››

I don’t remember learning it in high school (apart from mean-median-mode), and in college I took calculus-based statistics before finishing calculus. When I did come across statistics in school, it was … Continue Reading ››

Don’t Just Do Something, Stand There: Words of Advice from a Common Core Author

“Don’t just do something, stand there.” That’s a line Dr. Bill McCallum, one of the writers of the Common Core State Standards, used in his presentation at the California Algebra Forum in San Jose, CA, which I attended last week.

Dr. Bill McCallum, one of the writers of the standards, used the line, “Don’t just do something, stand there,” when introducing the Standards for Mathematical Practice. He described a how he uses this line frequently in his teaching and it immediately struck a chord with me.
